Description +
Tirzepatide is a dual agonist at GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) receptors, studied for its roles in glucose metabolism, appetite regulation, and body composition. Each 40mg vial is lyophilized, independently tested for identity, purity, and quantity by a third-party laboratory, and shipped with its batch COA number printed on the label. For research purposes only.
Storage & handling +
Store lyophilized vials refrigerated at 2–8°C, protected from light and moisture. After reconstitution with bacteriostatic water, keep refrigerated and use within the recommended window. Do not freeze reconstituted peptide.
Shipping & returns +
Orders placed before the daily cutoff ship the next business day via Canada Post Express (1–3 business days anywhere in Canada). Discreet packaging with no product labeling. Shipped from within Canada — no customs, no border delays.
