Peptides for Weight Loss: GLP-1 Medicines and the Lookalikes
Semaglutide and tirzepatide (the GLP-1 medicines) have strong human-trial evidence for weight, but they are approved prescription medicines, not research compounds. They need a licensed clinician, not a supplier.
Most discussed here: Semaglutide · Tirzepatide
The compounds
Each one leads with how strong its human evidence is, and what that rating is based on.

Tesamorelin
Approved for reducing excess visceral abdominal fat in people with HIV-associated lipodystrophy.
- Research peptidesMitochondrial-derived peptide (16 amino acids)
MOTS-c
Sold for metabolic health, fat loss and longevity. Studied in humans as a biomarker of exercise response.

MOTS-c: The Human Studies Are About Exercise, Not Injections
Every MOTS-c protocol online gives you milligrams. The human research measures your own MOTS-c rising after exercise. That gap is the whole story of this compound.
