Frequently Asked Questions
What is the difference between retatrutide, tirzepatide and cagrilintide?
Retatrutide activates three receptors (GLP-1, GIP, and glucagon), while tirzepatide activates two (GLP-1 and GIP). Cagrilintide acts on a different pathway: it is an amylin analog. The PeptiLine comparison details their mechanisms of action and published trials.
Do the GLP-1 vials have a certificate of analysis?
Yes, for retatrutide (10 and 20 mg) and cagrilintide: each published Janoshik report provides the lot number, the quantity measured, the HPLC purity, and a verification key. These are all available on the certificates of analysis page.
Why choose a pack of retatrutide rather than a bottle?
The R10 and R20 packs add bacteriostatic water, syringes and disinfectant swabs; the 30 and 60 mg packs bring together three vials at the lowest price per mg in the catalogue.
