Liraglutide
GLP-1 agonist
An earlier daily-injection GLP-1 agonist—still used for diabetes and weight loss.
Liraglutide was the first GLP-1 drug widely used for obesity (Saxenda). It works similarly to semaglutide but requires daily dosing and tends to produce somewhat less weight loss. Well-studied safety profile over many pa…
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…

Common questions
What is the difference between Liraglutide and Retatrutide?
Both are categorized under GLP-1 agonist in our directory—here is how they differ in name, use, and label context. Liraglutide is categorized as GLP-1 agonist; Retatrutide as GLP-1 agonist. Liraglutide: An earlier daily-injection GLP-1 agonist—still used for diabetes and weight loss. Retatrutide: A once-weekly GLP-1/GIP/glucagon receptor triple agonist in late-stage trials for obesity—next-gen metabolic peptide drug.
Are Liraglutide and Retatrutide 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 Liraglutide or Retatrutide 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.
