[Question] Australia — has anyone got a straight answer on purity
I have had 18 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 40 days on nominally the same lane, which matters more in summer than in February.
The independent number came back 96.8% against a claimed 97.2%, which I read as agreement rather than a discrepancy — inter-lab variance on this assay is a point or two either way and treating one lab as ground truth is how people end up in pointless arguments with vendors.
Batch number is in the comments. Ask if you want the method.
best — the order this archive was captured in
What were the related substances listed individually?
the method line is doing real work, not just window dressing
no "is this good?" without saying what the compound and claimed purity are
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.
Not convinced. The evidence does not support that reading.
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.

Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.
The confident tone is doing a lot of work that the evidence is not.
post the whole document, not the headline number
the batch number or it did not happen
redact your own name, not the vendor's batch details
