Semaglutide storage after reconstitution — 28-day stability data

Adding a me-too, because a thread of one person's experience is not much use. Posting only so the count is not one.

Storage question about storage and cold: my pen was left out of the fridge for 8 hours.

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: temperature monitoring strip inside package. If your peptide arrives warm, contact the vendor immediately. Don't assume it's still good.

Adding the numbers, since they settle part of this. Worth knowing that the injection site changes very little. Abdomen, thigh and upper arm are bioequivalent for semaglutide, so a site change is not a plausible explanation for a bad week.

Worth separating that from semaglutide, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

One thing that is still open after LabKate’s answer:

How much of the between-person variation is pharmacokinetic and how much is just adherence measured badly?
