tried purity for 3 weeks. here is what happened.
I have had 10 orders now and I keep a table, so here is the honest summary rather than a vibe. Material has been consistent. Communication has not. Shipping has varied by about 30 days on nominally the same lane, which matters more in summer than in February. The independent number came back 97.9% against a claimed…
The COA I was holding said 96.8% area and I thought it was trash. Turns out the method was solid and the impurity profile was clean.
area% is not mass%, and here is exactly why it matters
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.
What were the related substances listed individually?

Water content was 3.8%, acetate was 6.2%, purity was 99%, but net peptide was only 90% of the label weight. Perfectly honest, just chemistry.
axis labels included, always
That is net peptide content, not purity. Different number, different meaning.

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.
the batch number or it did not happen
That is net peptide content, not purity. Different number, different meaning.
