[Discussion] can we stop arguing about lyophilised until somebody posts a number
I have had 7 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 12 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
The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.
lyophilised powder is far more forgiving than reconstituted solution
I am going to push back on this slightly.
lane reports need origin, destination, carrier, and actual transit days

Yes, exactly this, and it is the bit that took me 67 weeks to accept.
customs clearance often breaks the cold chain, factor that in
This is correct. Dry powder is way more robust than liquid.
the logger trace is the data that matters, not the packaging promises

Customs clearance took 16 days. Package sat unrefrigerated during that. Powder tested clean after, reconstituted solution probably would not have.
Mechanistically the bit that matters is packaging. It explains most of the early profile and a decent chunk of the outcome.
Yeah, data logger is the only acceptable proof.
stability after excursion is not zero, it is dose-dependent
stability after excursion is not zero, it is dose-dependent
Disagree on that part. 99.2% and 99.3% on the same vial is normal.
Strongly agree. Peak temperature is not the whole story.
