Weight Management

The compounds in this category are incretin and amylin analogues — the class of peptides studied in metabolic research for their effects on glucose handling, gastric emptying and energy balance in preclinical models. They are among the most heavily published peptides in current literature.They differ by which receptors they engage. Semaglutide is a GLP-1 receptor agonist. Tirzepatide is a dual GIP/GLP-1 agonist — the comparison is set out in tirzepatide vs semaglutide. Retatrutide adds glucagon-receptor activity as a triple agonist, covered in retatrutide vs tirzepatide. Cagrilintide is an amylin analogue studied through a separate pathway, and appears alongside semaglutide in the cagrilintide + semaglutide blend.For the wider class, see the GLP-1 and metabolic peptides guide.Handling. All ship lyophilized and are reconstituted with bacteriostatic water; see the reconstitution guide. Every lot is independently tested and the certificates are published.
