Cold chain shipping for storage and cold: my last order arrived with the cold pack completely melted and the vial at room temperature. I contacted the vendor and they reshipped with better insulation.

What to look for in shipping: overnight or 2-day shipping only. If your peptide arrives warm, contact the vendor immediately. Don't assume it's still good.

The figures, for anyone assembling their own picture. One practical note: write down what you did and when, before you need it. Reconstructing a timeline from memory three months later is how people end up unable to answer the one question that would have resolved it.

Coming at COA_Karl’s question from a different direction. Whatever the answer turns out to be, the method for getting there is the same: state the assumption, do the arithmetic in public, and invite the correction. That is slower than asserting, and it is the only version that survives being wrong.

A narrower follow-up, since the general answer is now clear:

How long did you give it before you decided it was working?

Reporting back.

Follow-up — I binned the frozen one. Aggregation does not undo itself and I was not going to inject a maybe.
