The pack just landed. Here is your five-minute checklist.
Insulated packaging did its job in transit. The five checks below confirm everything arrived right and get each vial into correct storage within minutes.
Check one to three: package, label, batch
First, the packaging itself: the insulated wrap should still be intact and the inside noticeably cooler than room air. Second, match the vials against your WhatsApp order, compound and count. Third, find the batch number printed on each label. That number ties your vial to its production lot, so note it before the label ever smudges. If anything looks off, message the ordering chat right away with a photo, while the courier timestamp is fresh.
Check four: the powder
Lyophilized peptides should look like a small compact white puck or fine powder at the bottom of the vial. A loose powder that moved around in transit is normal. What matters is that it is dry: any sign the material has gone glassy, gummy or discolored is worth a photo to the chat before you do anything else. GHK-Cu is the exception on color: the copper complex is naturally blue-tinted even as a powder.
Check five: into the fridge, correctly
Unreconstituted vials go into the refrigerator at 2 to 8 degrees C, away from light and away from the door shelf where temperature swings live. Bacteriostatic water can stay at room temperature until first use. Reconstitute only what your protocol needs now: the 28-day refrigerated clock starts at reconstitution, not at delivery. The full handling walkthrough lives in the reconstitution guide.

Arrival questions
What should peptide powder look like on arrival?
A compact white puck or fine dry powder at the bottom of the vial. Powder that shifted loose in transit is normal. Discolored, gummy or glassy material is not, and is worth a photo to the ordering chat immediately. GHK-Cu is naturally blue-tinted from its copper complex.
Do vials need to go straight into the fridge?
Yes. Unreconstituted vials store at 2 to 8 degrees C away from light. Avoid the fridge door shelf, where temperature swings with every opening. Bacteriostatic water can stay at room temperature until first use.
What if something is wrong with my order?
Message the same WhatsApp chat you ordered in, with photos, as soon as you notice. The batch number on the vial label plus the courier timestamp makes any issue fast to trace and resolve.
When does the 28-day clock start?
At reconstitution, not at delivery. Sealed lyophilized vials keep far longer under refrigeration, so only reconstitute what your research protocol needs now.
