@mitchmiller , I'm glad you got your money back. I've ordered from them a couple of times. They do post multiple active batches and do have a disclaimer that your order could come from any batch. I am very cautious with them for that reason, notwithstanding the ILS lab drama. If there is a chance that I could get a batch from March, 2026 when they have fresh new batches in inventory, I don't order.

No, I defintely was not expecting zero. I guess my initial alarm was twofold: 1) The conflicting answers from AI and 2) I am used to seeing endotoxin test results expressed as EU/ML vs EU/VIAL. In the light of a new day and after doing some more digging, I believe the 6.543 endotoxin level is safe and does NOT reflect poor manufacturing standards. I spent some time arguing with AI last night and it concluded that the output that suggested that the 6.543 level was high was based on a "water measurement" and not dry powder. AI sees anything over a certain number and flags it as high and toxic. I'm good now. Thanks for everyone's help. I'm still learning.

@shifted, thanks the calculator is cool. I questioned AI on the 60mg vial, but i think the difference in level between 60 and 66 is nominal. I did state earlier that AI commented that that level of endotoxins won't give me a systemic fever, however it reflects, in part, poor factory quality control. I believe I know the drill by now..... in accordance with my risk tolerance, a decision needs to be made about what to do with those 10 vials. I guess I will wait to see what endotoxin levels come out of the third party testing group's review.

Update: Perhaps this is false alarm? Google is saying Ai suffered from a common hallucination. But enough with AI, I would love human opinions on this matter. Thanks in advance!

So in consideration of the high praises expressed by certain members or this community for Nexaph, I bit the bullet and pre ordered the nxp 2 60mg kit. The test results just came back and the endotoxin level reads as 6.543 EU/Vial. I have researched with Gemini and ChatGpt and while both generally agree I not get a fever, one of them expressly stated "It indicates a contaminated batch, which carries an unnecessary risk of local inflammatory side effects and reflects substandard manufacturing controls." I know somebody said don't preorder if you can't afford to lose that money, but I am totally bummed after all the high praises for this vendor. Comments? Do you agree that the endotoxin level for this batch is high? I did join the 3rd party testing group, which is currently underway

Yes there are peptides under 99% purity at crush. Just look under testing results on their home page. They also had 2 that failed heavy metals that were listed a few days ago in red, but they have since removed those products .

@commander, thanks for the explanation. Live and learn.....

Well, that is a bummer, since 2 of my favorite vendors, use ILS. Question/Comment: Based on my read of the comments posted about ILS, it appears that most issues come from private testing. In the context of vendors using ILS for multiple vial testing, ILS provides notes about their methodology, including a statement about where that 100% purity could come from. Is it possible that ILS favors vendor testing rather than private testing and that they are more lax when it comes to the latter? I'm just asking, as a recent newbie. For instance, on a popular ILS's vendor's COA, one note explains that non-peptide related impurities are excluded from peptide purity.

@geno, while I am not speaking for Mary, as a recent newbie, my first couple of orders were from Genpeptide, before I became a little more experienced in reviewing COAs. They do one vial basic testing for purity and ID. That's it. When I wrote to them if they were planning to do any additional testing based on what other competitor are doing in the marketplace, their response was that heavy metal testing is a farce (my words, but expresses their sentiment) in a simialr fashion to fentanyl. They will consider adding endotoxin testing in the future. BTW, I have used their product and have had no adverse effects.

Sorry to hear about your situation. The link to glacier aminos works for me when I click from peptide critic. I received a similar message from another vendor's website due to my antivirus software. In my case it was a problem created by vpn. Maybe you can check that. Otherwise, sorry, no other suggestions. The order looks legit. That appears to be Glacier's labeling
