GLP-1 receptor agonist research peptides
Incretin receptor agonist peptides are among the most studied compounds in metabolic laboratory research. This shelf groups them by receptor profile, so researchers can see the family at a glance: semaglutide (a GLP-1 receptor agonist), tirzepatide (a dual GIP/GLP-1 receptor agonist) and retatrutide (a triple GIP/GLP-1/glucagon receptor agonist). Not sure which nickname belongs to which compound? Our Sema vs Tirz vs Reta name guide sorts out the brand names, codes and GLP-1/2/3 slang. Every vial ships as a lyophilized powder, sealed, with free US shipping on every order. Lab research only, 21+, and absolutely no human use.

Quick questions
What is a lyophilized peptide?
Lyophilization is freeze-drying: the peptide solution is frozen and the water is removed under vacuum, leaving a dry powder "cake" at the bottom of the vial. That dry form is how labs usually receive and store peptides. Every peptide we sell arrives this way.
Can people or pets use these products?
No. Everything is sold for laboratory research only, not for human or veterinary use, not FDA-approved, and not for diagnosing, treating, curing or preventing anything. Full details are on the research-use page.
Can labs outside the US order from you?
They can. Delivery outside the US is a flat $40 per order, and US orders always ship free. Orders usually ship within 24 hours, and every package comes with tracking. Your country’s import and customs rules, and any duties, are your responsibility. More: Worldwide delivery.
