Retatrutide
GLP-1 agonist
A once-weekly GLP-1/GIP/glucagon receptor triple agonist in late-stage trials for obesity—next-gen metabolic peptide drug.
Retatrutide activates three incretin-related pathways, producing large weight loss in phase 2 trials (SURMOUNT-1 and related studies). It is not yet widely approved like semaglutide or tirzepatide. Prescription-only when…
Semaglutide
GLP-1 agonist
A GLP-1 receptor agonist peptide drug approved for type 2 diabetes and chronic weight management.
Semaglutide mimics glucagon-like peptide-1, slowing gastric emptying and increasing satiety. Weekly injection versions (Ozempic, Wegovy) produce significant weight loss in trials. It is a prescription drug—not a supple…

Common questions
What is the difference between Retatrutide and Semaglutide?
Both are categorized under GLP-1 agonist in our directory—here is how they differ in name, use, and label context. Retatrutide is categorized as GLP-1 agonist; Semaglutide as GLP-1 agonist. Retatrutide: A once-weekly GLP-1/GIP/glucagon receptor triple agonist in late-stage trials for obesity—next-gen metabolic peptide drug. Semaglutide: A GLP-1 receptor agonist peptide drug approved for type 2 diabetes and chronic weight management.
Are Retatrutide and Semaglutide the same peptide?
No. They are different molecules with distinct names on labels and in research databases. Always match the full INCI or drug name—not a nickname on the front of the package.
Can I buy Retatrutide or Semaglutide over the counter?
Prescription peptide drugs require a clinician and regulated pharmacy supply—they are not cosmetic INCI ingredients or bulk research powders sold like supplements.
