Body Protection Compound-157 / Gastric Pentadecapeptide

15-AA synthetic peptide from human gastric juice protein. Strongest preclinical evidence for tissue healing: muscle, tendon, ligament, bone, gut, neuro. No RCTs yet.

Thymosin Beta-500 / Synthetic Thymosin β4 fragment

Synthetic thymosin β4 fragment. Promotes angiogenesis, tissue repair, cell migration, reduces fibrosis. WADA banned. Popular in sports/bodybuilding.

Tβ4 / TB-4

43-AA endogenous peptide in most tissues. Promotes cell migration, angiogenesis, wound healing, anti-inflammatory. Not WADA banned. Engineered versions showing promise in diabetic wound healing.

Vyleesi / PT-141

FDA-approved for HSDD in premenopausal women. Works centrally (MC4R), not hormonally — unique mechanism vs PDE5 inhibitors or hormones.

Modified GRF(1-29) / Mod GRF

Synthetic GHRH(1-29) with MPA modification. Stimulates pulsatile GH release. Often paired with Ipamorelin for synergistic effect. WADA banned.

NNA / GHRP

Selective ghrelin mimetic. Stimulates GH release without affecting cortisol or appetite as much as other GHRPs. Often paired with CJC-1295. WADA banned.

Egrifta SV

FDA-approved GHRH analog for HIV-associated lipodystrophy. Stimulates endogenous GH, reduces visceral adipose tissue ~15%. Off-label aesthetic body contouring potential.

CBL / Neurotrophic peptide mixture

Mixture of neurotrophic peptides and amino acids. Approved in Europe/Asia for stroke, dementia, TBI. Crosses BBB. Not FDA-approved but available through specialty pharmacies.

Copper Peptide / GHK-Copper Complex

Human plasma tripeptide (Gly-His-Lys) bound to copper 2+. Declines with age. Stimulates collagen, tightens skin, reduces wrinkles/fine lines, promotes wound healing. Topical and injectable forms.

Wegovy / Ozempic

FDA-approved GLP-1 receptor agonist for type 2 diabetes (Ozempic) and chronic weight management (Wegovy 2.4mg weekly). Mean 14.9-16.8% body weight loss in STEP trials.

Mounjaro / Zepbound

First dual GIP/GLP-1 receptor agonist. Superior weight loss vs GLP-1 RAs alone. Up to 22.5% weight loss in SURMOUNT-1. Approved for T2DM (Mounjaro) and obesity (Zepbound).

Tα1 / Zadaxin

28-AA peptide from thymosin fraction 5. Immune modulator. Approved in 30+ countries (not FDA-approved). Used for hepatitis B/C, immune support, cancer adjunct. Restores immune balance in liver failure.
