what changed for me between month 12 and month 20
what changed for me between month 12 and month 20 — that is what I am asking, and I have already read the wiki twice.
Assumed regulatory status was static and it was not. Checked again this year and the answer had changed where I live.
Kept a reconstituted vial too long out of curiosity and learned something about solution stability I would rather have read.
Every claim I could trace in this board went back to about four papers. That was a sobering afternoon.
I will update this if the picture changes rather than quietly leaving it up.
best — the order this archive was captured in
Short peptides in solution are subject to hydrolysis and, depending on sequence, oxidation. Storage state and time in solution are practical variables that this board almost never discusses.

Agreed — and the preclinical to clinical gap is where nearly all the overclaiming happens.
ask for the mass spectrum, not just the purity number
Sent a vial to Janoshik: 98.9% against a claimed 98.5%, with the mass confirming the sequence. Both halves mattered to me.
short peptides are cheap, which cuts both ways
stability in solution is the practical question nobody asks
Paid for identity confirmation rather than just purity for the first time here. Worth it, and it is not the default on most certificates.
the human evidence is thin and the rodent evidence is not
Standing reminder in every thread here: research material is not approved for human use.
identity, quantity, stability — three separate questions
