Hello all,
Recently I switched to Nude Nicotine for the first time and ordered 1L which was delivered in two 500ml bottles. According to the spec sheets they sent, they come from lots A080 and lot C012. I opened one bottle and made a 2L 6mg batch with it, and it came out really, really harsh and much darker than I would expect (using my steeping process.)
I just tested it using my Wizard Labs nic test kit (following these instructions) and it came out near 158mg/ml. The only difference is I'm using a 18g 1ml syringe to titrate using the HCl instead of a 20g syringe as instructed. It took 9.8ml of HCl to titrate 1ml of nicotine solution in ~20ml of distilled water (poland spring).
I could see it if I were off by maybe .5ml, but it should only take ~6ml of HCl to titrate. I'm not incorrectly measuring by ~4ml.
I followed the instructions precisely. Last night, i ran the same test using a 6mg/ml 40ml test batch I made. I used 37.6ml pure VG and 2.4ml 100mg/ml nicotine solution, using the same 14g 5ml syringe, so even if mixing by volume is a problem it should matter since it's the ratio that matters, and I'm using the same piece of equipment to measure both the VG and nic. I had to make my own distilled water, but the results were the same. Coupled with the fact that vaping it was nigh impossible since it hurt so bad, and made me feel dizzy after 3 hits (Doge rda wide open at .45Ω and 6v on my 120w raptor), I can't see how it can't be nic heavy unless there is something about this process i'm doing wrong or don't understand.
I reached out to /u/NudeNicotine about this, and they informed me it's literally impossible for the 100mg/ml to be higher than 100mg/ml based on the manufacturing process.
any wisdom or advice is appreciated. Thanks in advance.
tl;dr: my nude nic seems to be around 160mg/ml, anyone else have this experience or knowledge on the subject?
###Update: Results http://www.reddit.com/r/DIY_eJuice/comments/2xz1ol/nude_nicotine_is_ridiculously_strong_follow_up/
Send us a sample! This is a definite first for us.
Just a little background - Bottles are filled to a MAXIMUM capacity with a 100mg/mL base formulation. The 6mg/mL formulation in a 500mL bottle would require 470mL of blank VG and 30mL of 100mg/mL nicotine. Our process entails adding of 470mL of VG, followed by the 30mL of nicotine base. 160mg/mL would overflow the container!!!!
Nonetheless, let's get a sample of this back in the laboratory and replace right away!!!!
Best, Jake
Sure thing, just ship it to the address on the website?
Please Please!!!
I'm also sending you a 500mL bottle of lot A082 out of good grace.
I am wholely thinking this a settling issue on your end. Mixing of 100% VG solution is damn difficult and really needs to be shaken well for a good 5min before use :)
I thank you for the bottle. Unfortunately, shaking doesn't explain both bottles (from different lots) having this problem, nor does it explain how I repeated the test after shaking it for 5 mins, which ended in a ~157mg/ml result. http://www.reddit.com/r/DIY_eJuice/comments/2xkh2i/nude_nicotine_ridiculously_strong/cp0xoyz
should I send in one of the 4oz bottles I broke my nic down into as well? I had this same problem and I would assume the more testing you did on different people's batches, the better it would be, to find out what exactly went wrong. I don't mind sending it in, as I can not do anything with it myself, as it is way too strong/harsh to put into customer's juice.
Absolutely! Let me kow how much shipping charges are and I'll be sure to cover ya :)
don't worry about covering the shipping, as I am curious as to what was up with this batch and ~$5 won't kill my wallet. I would, however, like to take you up on the 500ml for half off with free shipping offer that you offered when I was on the phone with you a little over a week ago. I already have 1L otw to me from you guys, but I want to stock up on nic. If you could PM me with details on how I would go about getting that 500ml that would be great! I've had a 500ml in my cart just waiting for the coupon code or whatever is needed to fulfill it.
I have the exact same lot and batch number. Would you like me to send a sample as well?
I have experienced this as well. Me and a few friends that I make juice for can no longer vape 6mg as it is too harsh. We have dropped to 3mg and it tastes more like 6mg used too.
The apparent increase in strength has everything to do with the freshness of your product :-) as this customer had not mixed and shaken their aliquot correctly, that was by what they were experiencing. Please to be advised your formulation is gc/ms verified at the concentration as indicated :-)
Thanks for the info.
Would you have any idea why my mixes have been unusually rough with the lastest liter I ordered then? I believe I ordered it less than two months ago and have kept in in the freezer since after asking a question on storage here and you guys actually responded. The 500ml bottles get transfered to 250ml glass bottles and stored in the freezer. I then only transfer the nicotine into 60ml glass dropper bottles that I use for mixing. It was stronger than normal from the get go.
Ive been very happy with my purchases from you guys, but like I said, with my latest batch I have to half (or more) the nicotine content in my mixes to even make it vapeable. I normally vape 6mg, but on this latest batch ive had to drop to around sometimes even 1.5mg to 3mg. Even then its still a little rough. All the people I mix for have even said the same thing.
By no means am I unhappy. In fact I just ordered another liter over the weekend, but someone was definitely off with this one.
Only reason I ask is because I was experiencing the same thing as OP and I got 100% VG as well, not to mention the lot and batch numbers are the exact same which would mean the same source correct?
Thank you.
Edit: It could be because I didnt shake this one very long now that I think of it. Definitely could be on my end. Would make sense as it seems hit or miss with the harsh throat hit.
Ill be sure to shake the ones I have coming extremely well haha.
From your background, are you not making batches of different concentrations of what you sell such as 3 to 100 mg/ml and quantitatively assuring the concentrations through your gas chromatograph-mass spectrum? This will rid the question that your technician failed to add the correct amount of dilute to your concentrated nicotine. If you are only confirming the concentration of your base concentration, you can not confirm that the diluting was incorrect before you send it out to the customer.
We are confirming that we test by gas chromatography for the individual deluded strength as well. This allows us to confirm a 1% threshold much more accurately than by a sulfuric acid titration :)
Well then if you have the laboratory analysis of the batch of each concentration you sell, this leads to only two reasons for such: 1) the qualitative titration test was incorrectly done and there is a 1/2 dilution factor within the reagent or by the operator, or 2) the phase seperation of a product sitting for a long time or lower temperature not allowing mixing. The difference of the specific gravity of nicotine and glycerin will let the nicotine sit on the top. This reddit tread should be deleted.
Commercial Juicemaker here...this is the main reason why I do not use 100% VG nicotine for production. Yes, it should come fully & evenly mixed, totally homogeneous, but in real world conditions, I've noted how difficult it is to work with. Hot spots and uneven distribution of nicotine happens, and even measuring it out is problematic, due to how much clings to the sides of cylinders and beakers. I personally use a 50/50, 60/40, or 70/30 PG/VG ratios for my nicotine. Easier to work with, especially in the quantities I use [55 gallon drums & 15 gallon barrels]. tl;dr - get a bit of PG in your nicotine, makes life easier.
Thanks for this. OP's experience with NN is interesting. Considering your thoughts regarding real-world conditions and your experience, one might expect the same result from any chemist firm...like Wizard Labs. I'm also very much assuming to your credit you're familiar with making juice if you're dealing with such large quantities. I go through nic so slowly (120ml of 100mg/ml has lasted me around five months at 2mg per 30ml batch. I vape ~10ml a day but i have made mixes for friends with higher nic percentages). Do you have a ratio you like best? I may try it...even though I just made a nic order yesterday.
MAX VG THO. I need dem smooth clouds. Also, i mix into my final destination so that I can avoid just these issues (everything goes in the beaker to stir for several hours, the mix that comes out is homogenized like crazy.)
I can dig it...but the issue is the nicotine distribution in the original container. NN measures out the pure to make whatever strength mg/ml, dumps it in the VG, and then throws it onto a drum roller or whatever for however long. They are a reputable lab, I know Jake, and I know they test it when they take it off of the roller and pour it off to be packaged and shipped. Then it has time to sit. And settle. This is just my thoughts on it, however. I would say to spin the straight VG nic again, BEFORE you take any to test, or to use in mixing. Secondly, 30mL of 6mg final strength juice is 1.8mL of 100mg/mL nic. So with 50/50 nic, it's an extra .9 mL of PG. I dig max VG, but I aim for 20/80 or 30/70...thick enough to drip, thin enough to tank. And I'm usually making 5 gallon batches of each nicotine level, so I understand that my experience is different from your DIY...but DIY is where I started, and this is what I have found works for me along the way.
I absolutely understand. Currently my production flavors are ~20% flavoring already, so I'm striving to keep the highest amount of VG possible. I can experiment with some PG/VG mixes for nic, see if I can deal with it.
I'm sure their QC is great, people swear by them and I know loads of companies use their nic in production, which is why I feel so blindsided here.
Also, for what it's worth, I redid the test after shaking the crap out of that 500ml bottle, probably shook it aggressively for ~5 minutes, it was full of bubbles, and I ran the test again. ~157mg/ml.
Holy shit I thought I was crazy. Usually vape 6mg, bought 50mg/ml from nude nicotine a couple weeks ago. Whipped up a batch that I've done many times before and thought I was Vaping 12-18 mg. So I figured they just accidentally labeled 100mg/ml as 50 and halved the nic in my recipes. Still strong but not as bad. What the hell.
Someone one ECF just recently asked a question along these lines. Why was his DIY 6 mg/ml mix utilizing Nude Nic so strong compared to the same strength commercial juices. Hmmm.
i just want someone else to be able to test this to make sure i'm not crazy. "6mg" is unvapable in a high wattage dripper, "3mg" is fine.
i just received a order of Nude Nicotine 100mg/ml and in my opinion its great quality. my idea is just that they are just really amazing at making true 100mg/ml if you notice too they send you test papers of the nicotine too.
im vaping 6mg,4mg, and 3mg (i still think 6mg isnt harsh) at 4.2v at .3ohms on a mutation 2 on sigeli 150w
I'm sure plenty of people have had great experiences with them, that's the reason I switched. But, like, is all other nicotine on the market sub par compared to theirs? because i've never had a commercially mixed 6mg taste this harsh, nor any of my own mixes using other nicotine.
I never bought a test kit, also never bought from nude, but you may be onto something here.
I've been using nude nicotine for a while now and when I make a 6mg with any other nic company and a 6mg with nude nic, the nude nic feels like a 3 compared to a 6mg and I've been through several liters of nude nic now and they've all been insanely consistent. The only possible things that could come to mind is either the nic is separating from the VG or you got a bad batch. Considering nude nics quality control, I'd have to say it's simply separating. Throw that nicotine in a beaker/flask, put it on a stirring hotplate, put it on the lowest heat setting you can, set it to spin as fast as it can, and let it mix for a few hours.
Did you shake the bottle properly before use? Gotta shake it a lot as vg is thick
I mean... I shouldn't have to shake nicotine, that's crazy. It should be homogenized... that's what I'm expecting from a high quality nic supplier. It shouldn't be that they mixed just this bottle and maybe it needs shaking.
Even so, a 2L batch requires 120ml of 100mg/ml to mix to 6mg, there is no way I went down 120ml and didn't get an averaged amount of nicotine.
Just shake it. Doesn't hurt to try, now does it? This is a very common problem
> I mean... I shouldn't have to shake nicotine, that's crazy. It should be homogenized...
That is simply not true! It may not be the issue in your case, but it is standard practice to shake any nicotine solution before use. Nicotine just doesn't dissolve very well in glycerine, and it will over time separate to some degree due to the difference in weights.
One should even shake low mg/ml nicotine solutions if they have been sitting awhile, as separation in those cases can mean not enough of it gets into the final juice, rather than too much when starting with a high dose solution.
Okay, but I get a 500ml bottle with a tiny little bit of air in it, how much will shaking really do? There isn't enough room in there for the liquid to really move around. I think that the nic should be homogenized before it's sent. This is dangerous stuff!
We have had the same experience. Definitely a lot more potent/harsher than what we have been accustomed to using other nic. Frankly we are unsure of the cause of it now, but we just recommend people to take a step down to compensate.
The weird thing is that some people say that it's not any harsher/stronger. I've recommended 1.5mg to people who normally use 3mg and they are thankful for it and they say it is exactly like the 3MG they are used to. While others have said that the 1.5MG was not enough and they wished they got 3MG.
It's kind of funny, but the majority lean toward it being like you have mentioned here.
Interested to see what comes of this and I'll gladly help out and chime in if anything is needed!
Been through the several liters of 100mg/ml 100% pg from nude nic and I've had the opposite experience. The nude nic feels like half the strength of any other company because of how smooth it is but you know you're getting that nicotine when your buzz feels the exact same as other companies at the same level. We usually recommend people bumping up their nic level because some of them want that throat hit.
Have you had a chance to test any of your nic? If you have a chance to do so that would be awesome, the more data we can get here the more sure we can be of what is going on.
Wow I just had the same effect! I mixed a 12 mg batch (from 100 mg from nude nicotine) and it ended being so strong! I just though that maybe it was due to the high qualitu of the nicotine as compared to other brand.
Edit: lot number B013 for me. Sorry but I don't have any kit to test it!
I'm not a new vaper, or a new DIYer. I've used Wizardlabs nic and nic from vaping extreme. I've vaped an awful lot, from dozens of different companies, and I've never felt 6mg as harsh as I vaped when i mixed that 40ml tester batch. Nor gotten nic sick as quickly. I know what nic sickness is like, and I know how it happens. I've vaped 12mg on a dripper for a review because that's what was sent to me after I moved down to 6mg for personal use, and I know how it feels and how quickly it can make you nic sick. I can't see how "cleaner, fresher" nic can be "harsher" when we're talking about a basic concentration. Coupling this with the tests I ran (assuming I did nothing wrong, I am not a scientist or doctor, nor do I play one on TV) and it leads me to believe it has to be over strong.
This doesn't feel like oxidized nic, it's not peppery, doesn't smell weird or taste weird, it feels like vaping 10-11mg when I want to be vaping 6mg.
Yeah I get what you're saying. Since I'm unable to test for the exact concentration right now I just ended diluting more the base I did. But that's strange since my lot is different than yours. As soon as I'm able to test the exact concentration I'll tell you!
Here's the strange part, which has me second guessing myself. This is from two different batches. All the tests I've run have been on the 2nd 500ml, which so far has been used only for this testing. The first 500ml I used for the 2L batch has the same issue, 6mg is insanely harsh and the color of the juice is way, way darker than any other batch at 6mg I've made.
Didn't /u/BleuXShadoW just go through something like this with his retail juice? Lots of people complaining about harshness, I think he assumed it had oxidized but maybe this was the issue.
yup, I just read through all the comments here and it seems this might be what it is. The nicotine tastes different than being oxidized. It is like ultra strong or something. I wish I had a test kit for times like these. This batch was from when they were having usps problems and it spent basically 2 weeks in shipment, so I thought it might have been through oxidation by being heated up and shaken around and such. It definitely is like it's double strength. The weirdest part is that even mixing a 3mg batch of juice, it would make the liquid change color pretty quickly as if it was at least 6-9mg/ml of nic in the juice. It tastes basically unvapeable. I can't vape higher than 3mg anymore without getting nicsick, but I made test batches for myself and tested it higher than that and it was just ridiculous how strong it was. I talked with them on the phone and they said I can get a 500ml half off with free shipping, which I guess is better than nothing, but I tried a few times this week to contact them to see how I could get that because I was ready to buy more. No answer or call back from my voicemail, so I went ahead and got a full liter, because I am about to run out of nic. The most recent 500ml I got from them is fine and did not have the superstrength like the one from early january, so I really hope it was just a 1-time mistake. I really hope it was the shipping process also and not a problem with their equipment or something. I hate this happened to us and I hope it was just a single event, as that really set me back a good bit. I am making 1 to 6mg batches now to personally test, every new bottle I get, just to make sure I don't send out that crazy shit again. Other than that one batch, I have been very pleased with NN and their product, so I would like to continue doing business with them, but if this happens again, seems like it will be time to swap to another vendor. I still have 350ml or so of that bad batch and I am tempted to send at least one of the 4oz bottles I have it broken down in to them to test out and see what the problem is. I'm surprised they didn't even ask if I could send any in for them to test, because nicotine is a kinda scary thing to have mislabeled.
I have been trying to pay more attention to nic quality. I know you said the NN was not oxidized. How would you describe nic that is oxidized?
I remember reading about that. I don't know if he tested the concentration, maybe he can chime in.
I did not test it and I am tempted to get a kit to test it. I am also tempted to send in one of the 4oz bottles I rebottled it into back to them so they can test it themselves. I made a comment below about my experience
I have a bottle with the same lot numbers as you, but it's 100mg/ml at 50/50. I'll test it in a bit and report back.
Edit: I diluted mine down to 50mg/mL using PG simply because I didn't have enough sulfuric acid to titrate 100mg/mL. I used 1mL of this solution in 20mL of distilled water. It took 15.4mL of .01M sulfuric acid to titrate. Using Nude Nicotine's calculation I got 49.97mg/mL. Double that due to my initial dilution and I get 99.95 mg/mL.
The first question I would ask is what is the nic suspended in? VG nic can develop hot spots as it sits or if it isn't blended well enough. When mixed in large batches, this can result in (for instance) 5 single gallons from a 55 gal batch that all titrate differently. I've seen it plenty of times from many different manufacturers, the difference being every single time anything like that happens, the vendor that I purchased from replaces it immediately. Nude telling you it's impossible without asking for a sample or something to check out scares me a bit, I would stop vaping it IMMEDIATELY or start mixing it as if it is exactly what you titrated it to.
I would also re-titrate it several times (we titrate every gallon that comes in five times and average the results) to ensure that you are accurate.
EDIT: If you would like, PM me and you can send me a dozen ml and I'll titrate it for you.
Thank you for the offer, I'll send you a few samples to titrate. It's a 100% VG suspension.
I've titrated the undiluted nic solution 3 times, twice with my homemade distilled water, once this morning with the poland spring distilled water. Each time, the results are between ~158-162 mg/ml - i've blown through a lot of HCl testing. I've titrated my 6mg/ml solution 5 times, 4 in my home made distilled water, once in the poland spring water. Same result. I was worried at first I couldn't trust my water (did a pot of water with a glass bowl floating in it, inverted lid filled with ice), but the results are the same across both.
Shooting you a PM now.
I may have missed this in the comments, but have you tested the nic solution straight out of the bottle, before diluting?
If you said you have, my apologies for missing that.
I normally only buy the 12mg and dilute it to 6 as well, and sometimes it is a bit harsh and peppery. So I'd be interested to see what your tests say on the undiluted sample.
Edit: I'm pretty sure I misunderstood your initial comment, and the 100mg showed 158mg, undiluted... Correct?
I've tested it both before diluting and after diluting. Results are approximately the same.
Wait, it shows 160mg even when diluted..?
If there is one lesson to be learned from this thread - -PLEASE PLEASE shake before use everyone!
We are updating our labels to reflect this disclaimer
I just want to make clear that I have said several times in this thread that I took that suggestion, shook the bottle vigorously for five minutes and readministered the test. I got a result of 157mg/ml.
Just wanted to chime in after having run a nicotine test on my 100 mg/ml 100% VG batch from NN -
Nicotine Lot # - A080 VG Lot # - C012 Order placed on January 22nd, 2015
Test clocked in at 101.244 mg/ml after 3 mins of pre-shaking the nic to ensure it was fully mixed.
Took 10.4 ml of Sulfuric Acid .12N to titrate 2ml of the nicotine.
FWIW, my current bottle of Nude is from the same batch numbers (A080/C012), although it's a 72mg/ml concentration (still 100% VG base though.) Mine seems to be the proper concentration and I haven't had any issues with getting nic sick, even chain-vaping (I make 6mg juice.) I shake the crap out of everything before I sit down to mix juice, just as a matter of habit, but I haven't run into any nic hotspots, harsh tasting juice or anything like that.
Since my nic and VG are from the same lots as the OP's, I'm inclined to think it was a mixing/bottling error for OP's bottles, not necessarily a problem with the actual nic batch from the manufacturer.
I'm interested to see what you find. I have an unopened 250ml bottle with those exact batch numbers sitting in my fridge. I'd pull it out and give it a whirl, but I do not have a test kit so it'd be somewhat useless.
just mix up a 40ml with straight VG at 6mg/ml, 37.6ml vg 2.4ml solution. I ran it on my stirrer for ~1 hour at temp and it's fully mixed, so i'm not getting more nic in my dripper or something. i've tested nearly 15ml of that 40ml batch I made because I wanted to make sure I wasn't running the test incorrectly. I ran it with my home made distilled water several times last night, and I ran it again this morning using the poland spring distilled water. The blue looks the right color for pH neutral when I add it to the water.
I have seen people discuss this before. The answer I have seen (although I'm too busy to find it right now) is that since it is higher quality, less has been oxidized and it is thus more pure. I don't know if that is the actual reason, but it makes sense
It makes sense i guess, but it's just VG and nic. More pure should mean it's cleaner if anything, I've had impure nic and it's tasted chalky, or fishy. Not harsh, like too much nic feels.
I'm getting the same thing, although I haven't tested mine. Mixed by weight at 3mg, and it feels more like 6mg, possibly 12.
I'd get over the all VG fade, chance are you aren't sensitive to PG, its very rare allergy. Nic in 100% PG is much easier to work with, and i seem to get more consistent results
My Juice had major problems when i tried to max my vg, now my base is always 70vg/30pg, plus my nic is PG, and my flavors are mostly PG too. Clouds are just as massive as before. and everything feeds better as well.
I like to vape in a dripper at high wattage, keeping pg to a minimum just means it's as smooth as possible. I don't want to add any PG I don't have to.
What is the molarity of your hcl? Maybe it is weaker than it should be for testing this. Only thing I can think of.
.10N - the instructions I linked in the OP give you directions for using a .12N HCl solution as well, so unless wizardlabs mislabeled this or I got a bad batch of solution, I can't see that being the issue. I dunno if you saw but I tested a 100mg/ml in PG solution i had in the fridge that's about a year old which tested out to 107mg/ml using the same stuff.
I've use to order 500mL bottles of 100% VG from Nude, but I've stopped and switched to other vendors. Exact same experience. The nicotine doesn't taste like bad nicotine, just really harsh. I vape 3mg, and had the same issue. Harsh. I had a friend who I've always made juice for at 12mg, and NN was just too harsh for them as well.
I don't know where you're at but I've had some frosty deliveries lately including one that spent the weekend parked on a truck between 0-8°F. I wonder if there was some freeze and thaw involved to separate the the content from the carrier, or if that would be a possibility.
Looks like I might have to hold off on my next order or Cholar.. Lol JJ, u still have some?
This thread is pretty disturbing. I just ordered a 500ml bottle of 60mg in pure VG, and now I'm nervous about using it. Based on all of the negative feedback in this thread alone, I instantly regret my purchase. This was my first DIY order.
I ordered my current nicotine from them a few weeks ago and haven't had any issues. I vape 3mg and so does everyone else I mix for. But I haven't noticed any difference at all. 6mg is too strong for me so I'm pretty sensitive to it.
I wouldn't worry. Although I'm no expert. I think there are too many variables to 100% believe the testing. Just make sure you shake it up for a bit. If it's a problem they will make it right. They stand behind their product and service.
I have a new 500ml bottle of 100mg in PG that I haven't used (except to pour some into a smaller container,) and while I'm very curious to see what comes of this, I'm not worried at all because I'm certain it will be made right if there's a problem.
If you are worried about too much nicotine, just start mixing with a lower percentage, and gradually go up to your desired level. Your first DIY order is not ruined :)
For now we have one persons test pointing to too strong nicotine, with anecdotes to back it up. We also have people saying the opposite. I'd wait for some more results before I start worrying, even if there is a problem with their production, discovering it is the best way to start fixing it. No use in starting a witch hunt yet.

The error is honestly much less concerning than their response to it. Claiming that it is impossible, stating several times in the thread that this is the customer's fault, and then finally "generously" replacing half of his order.
Add me to the list as well, I ordered 1L of 50mg @ 50/50 Lot #A080 PG#B013 VG#C012. When I got it I shook both bottles for 3mins at room temp and using a timer, then I broke them down into 4oz glass bottles and placed them in the chest freezer. I just got into the first 4oz bottle last week to mix a batch for a friend at 12mg and 6mg for his wife. He told me that both were way too strong and harsh. He thought the 6mg was a 12mg and that I was trying to kill him with the "12mg". With me being at 3mg I did not even try the 12mg. So I tried the 6mg I made for his wife and it was way harsh for a 6mg. This was just an observation but I started to think I screwed something up. After seeing this thread I mixed one at 3mg this morning, the first time "I" have used nic from this batch and it definitely seems to be quite a bit harsher than my 6 month old batch from VT after going through half a tank.
What should I do? I think "I" can stand it at 3mg but anything above that just seems way to harsh.
I've chalked up just about everything I've made so far to a loss. What batch number is your nic from?
RESULTS confirmed - this customers sample as shipped from our laboratory tests @ 100mg/mL within a 1% threshold - 99.87mg/mL after area calcs. GC/MS-verified @ this concentration - our end-of-all standards (while the info generated here was on sulf. acid titration)

I am at a loss for words on your testing procedures sir. Bottle was definitely compromised upon receipt but not @ our laboratory :( New solution should be at your doorstep to move forward.
