Weight loss and metabolic
The FDA-approved peptides for weight loss are semaglutide, tirzepatide and liraglutide, as shots and a pill. What else is sold, and what the trials show.

Peptides, without the bro-science.
Every peptide we cover, organized by what it actually does. Clinical evidence, regulatory status, and what to ask a licensed clinician — written for adults who want the honest version.

Seven working categories.

Sexual wellness and desire
Melanocortin agonists, oxytocin, kisspeptin; libido and reproductive signaling pathways.

Recovery and healing
BPC-157, TB-500, KPV, GHK-Cu and the growth-hormone peptides sold for injury, muscle and sports recovery: the human trials behind each, and FDA status.

Performance and muscle
No peptide is FDA-approved for muscle growth. Ipamorelin, CJC-1295, MK-677 and the other growth-hormone boosters sold for it: the trials and WADA rules.

Cognitive and mood
Peptides for anxiety, focus and memory: Selank, Semax, Cerebrolysin and Dihexa. None is FDA-approved; what the Russian and Western evidence shows.

Longevity and anti-aging
Telomere, mitochondrial, and immune-related compounds; mostly research-stage outside Tesamorelin and Sermorelin.

Skin & hair topical and growth
Peptides for skin and hair growth: GHK-Cu, Argireline, Matrixyl and PTD-DBM. Which are cosmetic ingredients, which are drugs, and what the trials show.
GLP-1 Wegovy pill vs injection The Wegovy tablet, approved in December 2025, is 25 mg taken every morning on an empty stomach. The injection is 2.4 mg once a week. The tablet needs ten times the milligrams because almost none of it is absorbed, and in its trial it produced 13.6% weight loss against the injection's 14.9% in a separate trial. Updated Nov 11, 2026 GLP-1 Wegovy vs Ozempic Both are semaglutide from Novo Nordisk. Ozempic is the diabetes product and stops at 2 mg a week; Wegovy is the weight product and goes to 2.4 mg, with a 7.2 mg strength above that and, since December 2025, a daily tablet. The approved uses, the doses, the trials and what each costs. Updated Nov 11, 2026 GLP-1 Zepbound vs Mounjaro Zepbound and Mounjaro are the same molecule, tirzepatide, from the same company, in the same strengths and the same devices. What differs is the approved use, and everything that follows from it: which trials sit behind each label, who prescribes which, and what insurance will pay for. Updated Nov 11, 2026 Recovery BPC-157 vs TB-500 Two recovery peptides compared — mechanism, what the human evidence does (and does not) show, safety, and whether stacking is worth it. Updated Nov 9, 2026
