Human RCT Evidence

Human RCT Evidence is a recurring topic in our peptide coverage. This hub collects every article tagged Human RCT Evidence, newest first, each evidence-graded and tied to real, verifiable sources.

Weight Loss & Metabolic

Best Peptides for Stubborn & Visceral Fat: Evidence Ranked

A clinical-evidence ranking of the peptides that actually reduce visceral (belly) fat — one of the rare peptide topics with genuine Grade A human RCT proof — separating the FDA-approved and investigational incretin/GHRH drugs from the gray-market 'fat-loss' peptides that have none.

Weight Loss & Metabolic

Best Peptides for Insulin Sensitivity & Blood Sugar: Evidence Ranked

A clinical-evidence ranking of the peptides marketed for insulin sensitivity and blood-sugar control — the incretin drugs that actually work in human RCTs, and the 'mitochondrial' research peptides that do not yet.

Peptide Encyclopedia

VIP (Aviptadil): Evidence, Mechanism, Dosing & Legal Status

A clinical monograph on vasoactive intestinal peptide (VIP) and its synthetic form aviptadil (Zyesami/RLF-100) — a mechanistically compelling neuropeptide whose largest, best-controlled human trials in COVID-19/ARDS failed.

Peptide Encyclopedia

Tirzepatide: Evidence, Mechanism, Dosing & Legal Status

A clinical monograph on tirzepatide — the dual GIP/GLP-1 co-agonist sold as Mounjaro and Zepbound. Grade-A RCT evidence for diabetes, obesity and sleep apnea, with a boxed warning and a tightening 2026 compounding landscape.

Peptide Encyclopedia

Thymosin Alpha-1: Evidence, Mechanism, Dosing & Legal Status

A clinical monograph on thymosin alpha-1 (Zadaxin/thymalfasin) — an immune-calibrating thymic peptide with real human RCTs in hepatitis B, a negative phase 3 sepsis trial, and an unsettled 2026 US legal status.

Peptide Encyclopedia

Thymogen (Oglufanide): Evidence, Mechanism & Status

A clinical monograph on Thymogen / oglufanide / IM-862 (Glu-Trp) — the rare bioregulator peptide tested in real human RCTs. A Grade-A negative oncology result, a Grade-B human VEGF effect, and weakly-evidenced 'immune support' claims.

Peptide Encyclopedia

Tesofensine: Evidence, Mechanism, Dosing & Legal Status

A clinical monograph on tesofensine (NS2330) — the triple monoamine reuptake inhibitor sold through gray-market 'peptide' channels for weight loss. Real Phase 2 RCT data, no approval anywhere, and WADA-prohibited in 2026.

Peptide Encyclopedia

Tesamorelin: Evidence, Mechanism, Dosing & Legal Status

A clinical monograph on tesamorelin (Egrifta / EGRIFTA WR) — the FDA-approved GHRH analog with genuine Grade-A human RCT evidence for visceral fat in HIV lipodystrophy, and an unproven non-HIV anti-aging market.

Peptide Encyclopedia

Teriparatide: Evidence, Mechanism, Dosing & Legal Status

A clinical monograph on teriparatide — recombinant human PTH(1-34), the first bone-anabolic osteoporosis drug. Grade A RCT fracture data, a clear anabolic mechanism, and a 2026 status with no controlled-substance restrictions.

Peptide Encyclopedia

Survodutide: Evidence, Mechanism, Dosing & Legal Status

A clinical monograph on survodutide (BI 456906) — the investigational once-weekly GLP-1/glucagon dual agonist. Grade A randomized evidence in obesity and MASH, but not approved anywhere as of mid-2026.

Peptide Encyclopedia

SS-31 (Elamipretide): Evidence, Mechanism & FDA Status

A clinical monograph on SS-31 / elamipretide (Forzinity) — the cardiolipin-binding, mitochondria-targeted tetrapeptide. First FDA-approved for Barth syndrome in 2025, yet negative on every other large trial's primary endpoint.

Peptide Encyclopedia

Orforglipron (Foundayo): Evidence, Mechanism & Status

A clinical monograph on orforglipron — the first oral, non-peptide small-molecule GLP-1 receptor agonist, FDA-approved as Foundayo in 2026 for chronic weight management, with Grade A Phase 3 RCT evidence.

Peptide Encyclopedia

Semaglutide: Evidence, Mechanism, Dosing & Legal Status

A clinical monograph on semaglutide — the long-acting GLP-1 receptor agonist behind Ozempic, Wegovy and Rybelsus. Grade-A human RCT evidence across diabetes, obesity, cardiovascular, kidney and liver disease.

Peptide Encyclopedia

Retatrutide: Evidence, Mechanism, Dosing & Legal Status

A clinical monograph on retatrutide (LY3437943) — Eli Lilly's investigational triple GIP/GLP-1/glucagon agonist with the largest pharmacologic weight loss reported to date, graded A on human Phase 3 RCTs, but FDA-unapproved and WADA-prohibited as of mid-2026.

Peptide Encyclopedia

PT-141 (Bremelanotide): Evidence, Mechanism & Legal Status

A clinical monograph on PT-141 (bremelanotide) — the centrally acting melanocortin agonist FDA-approved as Vyleesi for premenopausal HSDD. Grade-A human RCT data, a narrow label, and a real pressor and pigmentation safety profile.

Peptide Encyclopedia

Pramlintide (SYMLIN): Evidence, Mechanism & Legal Status

A clinical monograph on pramlintide — the synthetic amylin analog and only non-insulin mealtime adjunct FDA-approved for type 1 and type 2 diabetes, with Grade-A human RCT evidence and a boxed warning for severe hypoglycemia.

Peptide Encyclopedia

Oxytocin: Evidence, Mechanism, Dosing & Legal Status

A clinical monograph on oxytocin — the posterior-pituitary nonapeptide that is an FDA-approved obstetric drug (Grade A) yet a largely failed intranasal 'bonding' peptide. Two drugs, two very different evidence bases.
