    @pep_researcher nexaph when I questioned the coa purity, didn't keep the email as I was sort of turned off

    @BMAR Hmmm having receipts would be better.

    Why would Nexaph make such claims when you can just go on their website and check COAs of other non GLP peptides with 99+ purity? That's what I did.

    Hard to believe your claim.

      @bmar , the email response was correct. Only NXP 1P, NXP 2P, and NXP 3P carry a 99% purity guarantee. All other products carry a 97% purity guarantee. See FAQ section on home page. @pep_researcher, i think the distinction here is guaranteed purity vs actual purity.

          @icynemby I see. But is that FAQ recently added after the Tesa back to back batches test results or was it always there? Their recent KPV is sitting at sub 99 purity too.

            I noticed Aavant's latest Tesa batch also sits at 97% purity, Janoshik COA.

            97.98 average purity, I'd call that 98.

            I have heard that Tesa, at 44 amino acids, is much more difficult to manufacture than the other GHRH analogs which are 29, and therefor results extra broken proteins which will affect the purity and make hitting 99%+ more difficult.

            This leads to a potency issue. Now I certainly wouldn't want something in the 96% range or lower, a 97.98 average purity is probably on par with what everyone's been using this whole time, and those COAs claiming 99%+ were mostly doing less effective testing protocols.

              @pep_researcher, I honestly don't know. Maybe someone with a bit more Nexaph experience can answer that one.

                @pep_researcher @icynemby It used to be 99 for GLP products and 98 for the other stuff they reduced the 98 to 97 recently due to Janoshik's latest results. Jano has updated its testing methodology with more recent 100pct reference standards so the results are extremely accurate. My guess is they have been off in the past by a small margin like 1pct. The standards have always been there for the GLP products but testing is improving on all the other peptides. This is my understanding from their telegram and I have asked the question.

                Some of the labs have been heavily investing in reference standards I have posted this before. Vanguard has supposedly spent 150k over the last 6 months. Jano double that. The standards allow the lab to pinpoint the peptide and get accurate results without filtering

                  Bottom line the Tesa has probably always been 97pct but the testing showed 99. Vanguard and Jano for sure are going to show lower purity results on multiple non glp peptides than other labs

                  I also ordered the Tesa so I guess I will find out the hard research way

                    @Stevepep I see. I checked Peptidology Tesa as they are one of the very few remaining stateside resellers using Vanguard consistently. Their batches are showing 99% on Tesa.

                    Skye and Peptide Crafters used Janoshik consistently until a few months ago. But now they too have moved to new kids around the block.

                      @stevepep It's a good sign that testing labs are upping their game.

                      @bmar No hard feelings, this forum is particular about receipts, which I like, and so I pressed for that.
