BPC-157
Body Protection Compound-157
BPC-157 is a synthetic 15-amino-acid peptide based on a fragment of a protein found in human gastric juice. It is studied for tendon, ligament, muscle and gut healing. Nearly all of the evidence comes from animal and cell studies; no human trial has shown it works for injuries or established a dose.
TB-500
Thymosin Beta-4 (TB-500)
TB-500 is a research-peptide name for synthetic thymosin beta-4, a 43-amino-acid peptide the body makes that is involved in cell migration and tissue repair; some products sold as TB-500 may contain only a short fragment of it. It is used in practitioner protocols for soft-tissue injuries, often alongside BPC-157. Evidence for injected TB-500 comes from animal and cell studies, and there is no human dosing data.
GHK-Cu
Copper Tripeptide-1 (Glycyl-L-Histidyl-L-Lysine + Copper)
GHK-Cu is a copper-binding tripeptide (glycyl-histidyl-lysine) that occurs naturally in human plasma and is widely used in skin-care products. It is studied for skin repair, collagen production and wound healing. Evidence comes mainly from cell, animal and cosmetic skin studies; injected GHK-Cu has not been tested in a human trial.
CJC-1295 + Ipamorelin
GHRH analog + Ghrelin-receptor agonist (synergy stack)
CJC-1295 + Ipamorelin is a two-peptide combination used to raise the body's own growth hormone release: CJC-1295 is a growth-hormone-releasing hormone (GHRH) analog and ipamorelin is a selective ghrelin-receptor agonist. It is used in practitioner protocols for IGF-1, sleep and body composition. Neither peptide is FDA-approved; there are small human studies of each separately and none of the combination.
Semaglutide
GLP-1 receptor agonist (Ozempic, Wegovy)
Semaglutide is a once-weekly GLP-1 receptor agonist that lowers appetite and blood sugar. It is FDA-approved for type 2 diabetes (Ozempic) and chronic weight management (Wegovy), backed by large phase 3 trials. In the main Wegovy trial, adults on 2.4 mg weekly lost an average of 14.9% of body weight over 68 weeks.
Tirzepatide
GLP-1 + GIP dual receptor agonist (Mounjaro, Zepbound)
Tirzepatide is a once-weekly injectable that activates both the GLP-1 and GIP receptors, lowering appetite and blood sugar. It is FDA-approved for type 2 diabetes (Mounjaro, 2022) and chronic weight management (Zepbound, 2023). In the SURMOUNT-1 trial, adults on 15 mg weekly lost an average of 20.9% of body weight over 72 weeks.
Retatrutide
GLP-1 + GIP + Glucagon triple receptor agonist (Eli Lilly LY3437943)
Retatrutide is an investigational once-weekly injectable that activates three hormone receptors: GLP-1, GIP and glucagon. It is in phase 3 trials for obesity and related conditions and is not FDA-approved. In its phase 2 trial, adults on 12 mg weekly lost an average of 24.2% of body weight over 48 weeks.
MK-677
Ibutamoren — orally-active ghrelin receptor agonist
MK-677 (ibutamoren) is an oral, non-peptide drug that mimics ghrelin to raise growth hormone and IGF-1. It has been tested in human trials — including a 2-year trial in healthy older adults and a trial in Alzheimer's disease that found no effect on disease progression — but it is not approved for any use. Known downsides include increased appetite, fluid retention and higher blood sugar.
MOTS-c
Mitochondrial-Derived Peptide (16-amino acid)
MOTS-c is a 16-amino-acid peptide encoded in mitochondrial DNA that acts on AMPK, the cell's energy sensor. It is studied for insulin sensitivity, obesity and age-related decline in physical function. Evidence comes from mouse and cell studies; no human trial has tested MOTS-c doses.
Sermorelin
GHRH (1-29) — recombinant growth hormone releasing hormone analog
Sermorelin is a synthetic version of the first 29 amino acids of growth-hormone-releasing hormone (GHRH) that prompts the pituitary to release its own growth hormone. A sermorelin drug (Geref) was once FDA-approved for diagnosing and treating growth hormone deficiency in children; it was later taken off the market, and the FDA has said this was not for reasons of safety or effectiveness. Adult use for IGF-1, sleep or body composition is off-label and rests on small human studies.
Tesamorelin
GHRH (1-44) analog — Egrifta
Tesamorelin is a synthetic analog of growth-hormone-releasing hormone (GHRH) that prompts the pituitary to release growth hormone. It is FDA-approved (as Egrifta) only to reduce excess abdominal fat in adults with HIV and lipodystrophy. In a phase 3 trial, 2 mg daily for 26 weeks reduced visceral (deep belly) fat by 15.2%, versus a 5.0% increase on placebo.
Liraglutide
GLP-1 receptor agonist (Saxenda, Victoza)
Liraglutide is a once-daily GLP-1 receptor agonist that lowers appetite and blood sugar. It is FDA-approved for type 2 diabetes (Victoza, 2010) and chronic weight management (Saxenda, 2014). In the main Saxenda trial, adults on 3 mg daily lost an average of 8.0% of body weight over 56 weeks, versus 2.6% on placebo.
Thymosin Alpha-1
TA-1 — 28-amino-acid immunomodulator (Zadaxin)
Thymosin alpha-1 is a 28-amino-acid peptide, first isolated from the thymus, that helps regulate immune responses, especially T-cell function. A synthetic version, thymalfasin (Zadaxin), is approved in a number of countries outside the US, mainly for chronic hepatitis B; it is not FDA-approved. Off-label use for post-viral recovery or immune aging is not supported by strong trial evidence.
Epitalon
Epithalon — synthetic tetrapeptide (Ala-Glu-Asp-Gly)
Epitalon (epithalon) is a synthetic four-amino-acid peptide (Ala-Glu-Asp-Gly) modeled on epithalamin, an extract of the pineal gland. It is promoted for longevity, sleep and melatonin regulation. Evidence is mostly from cell and animal studies; a limited 2002 human study used synthetic Epitalon injections around the eye for retinitis pigmentosa. Longevity studies used epithalamin rather than Epitalon, and there is no established systemic or longevity dose.
Selank
TP-7 — synthetic heptapeptide (anxiolytic nootropic)
Selank is a synthetic seven-amino-acid peptide based on tuftsin, a natural immune peptide, developed in Russia as an anti-anxiety medicine. It is not approved in the US or EU. Evidence comes from small Russian clinical studies in anxiety and from animal studies; there are no Western trials.
Semax
ACTH (4-10) analog — synthetic heptapeptide (nootropic)
Semax is a synthetic seven-amino-acid peptide derived from a fragment of ACTH (4-10), developed in Russia for stroke and cognitive disorders. It is not approved in the US or EU. Evidence comes from Russian clinical studies, mainly in stroke, and from animal studies; Western trials are lacking.
DSIP
Delta Sleep-Inducing Peptide — 9-amino-acid neuropeptide
DSIP (delta sleep-inducing peptide) is a nine-amino-acid peptide first isolated in the 1970s from the blood of rabbits in which sleep had been induced. It is used in practitioner protocols to try to deepen sleep. Evidence comes from animal studies and small, older human studies with inconsistent results; it is not an approved drug, and how it works is still unclear.
