Overview
GET IT RIGHT. KNOW YOUR COLOUR.
Wondering what colour your peptide should be after mixing? This guide shows you the expected look of each peptide and combination stack after proper reconstitution. Most peptides come out colourless or clear — a few have a distinct colour built right into their chemical structure.
If yours looks noticeably different from what’s described below, contact Pep Hub support before using it. You can also check the batch in The Receipts and confirm your lot with Check Your Vial.
