About ThePeptide
thepeptide.ca is a Canadian research-peptide supplier shipping domestically from Canada.
Every batch we sell is tested twice: we require a certificate of analysis from the manufacturer, then send the same lot for independent third-party testing before it goes on sale. Both COAs are published on the product page, matched to the lot number printed on your vial — so you can verify what you received, not just what the catalogue claims.
We also publish our testing record rather than just describing it. Our most recent fill-accuracy study covers 18 consecutive lots, showing measured content against label claim for each one.
Orders ship from Canada with tracking. Questions about a specific lot or COA go straight to us, and we answer them.
