Animal only BPC-157: Big Claims, Almost No Human Evidence A synthetic peptide marketed for healing, but human data is limited to a few tiny uncontrolled studies. It is unapproved and banned in sport.
Preliminary human CJC-1295 A long-acting GHRH analog that raises GH and IGF-1 in short human trials, but has no clinical-outcome data, is not FDA-approved, and is banned in sport.
Preliminary human DSIP (Delta Sleep-Inducing Peptide) DSIP is a naturally occurring brain peptide studied for sleep in small, dated trials with mixed results; modern human evidence is essentially absent.
Preliminary human Epitalon (Epithalon): What the Evidence Actually Shows Epitalon is a synthetic pineal tetrapeptide marketed for anti-aging; human data on the peptide itself is sparse, mostly Russian and from a single research lineage, with safety largely uncharacterized.
Preliminary human GHRP-6: well-mapped pharmacology, unproven benefits An old growth-hormone-releasing peptide that reliably raises GH and appetite in humans, but whose marketed muscle, fat-loss, and disease claims lack solid trials.
Preliminary human Gonadorelin: Strong in a Narrow Lane, Unproven for the Popular One Gonadorelin is synthetic GnRH with decades of human data in GnRH-deficiency, but no trial evidence for the TRT-adjunct use that drives its popularity.
Preliminary human Hexarelin: A Potent GH Trigger That Stalled at Early Human Trials A synthetic ghrelin-mimicking peptide that reliably spikes growth hormone in small studies, but was never approved and is banned in sport.
Animal only IGF-1 LR3 A long-acting synthetic IGF-1 analog with anabolic effects in animals and cell culture, but no human trials for its marketed uses; not FDA-approved and banned in sport.
Animal only IGF-1 DES A naturally occurring, shorter and more potent variant of IGF-1 with anabolic effects in rodents and cell culture, but no human trials for its marketed uses; not approved anywhere and banned in sport.
Preliminary human Ipamorelin A selective growth-hormone-releasing peptide with early human safety data but a failed efficacy trial; never approved and banned in sport.
Animal only KPV: A Promising Anti-Inflammatory Tripeptide With No Human Trials A three-amino-acid fragment of alpha-MSH with strong anti-inflammatory effects in animal and cell studies, but zero published human trials. Unapproved and gray-market.
Animal only MGF (Mechano Growth Factor) MGF is a muscle-derived splice variant of IGF-1 with a plausible repair-signaling mechanism, but no human drug trials exist — the evidence is animal and cell-culture only, and it is banned in sport.
Preliminary human Sermorelin Sermorelin is a synthetic GHRH fragment that nudges the pituitary to release growth hormone; human data is old and thin, with no modern anti-aging RCTs.
Animal only TB-500 (Thymosin Beta-4 Fragment): What the Evidence Actually Shows TB-500 is a synthetic thymosin beta-4 fragment marketed for healing, but human data on the fragment itself is essentially absent and the supporting research is animal-only.
Preliminary human Thymalin A Russian thymus-extract peptide preparation studied for immune modulation; the human data is real but thin, small, mostly non-blinded, from one research lineage, and unreplicated outside Russia.
Preliminary human Thymosin Alpha-1 A thymus-derived immune-modulating peptide with real but mixed human trial data: helpful in hepatitis B, but negative in the largest sepsis trial.
Preliminary human Thymosin Beta-4: Real Human Trials, But the Best Indication Has Missed Two Phase 3s Full-length thymosin beta-4 has genuine human trials for eye-surface and wound healing, but the evidence is small, sponsor-driven, and largely missed its primary endpoints.
