Semaglutide / Tirzepatide (GLP-1)

Metabolic
Human RCT Strong Animal Supportive
Risk: High

GLP-1 receptor agonist; slows gastric emptying, amplifies insulin release in response to glucose. Only peptide class with strong human RCT evidence for weight loss and glycemic control in non-diabetic adults.

BPC-157

Recovery / Healing
Human RCT None Animal Extensive
Risk: Speculative

"Body Protection Compound"; rodent GI and tendon-healing data dominates the literature. Zero completed RCTs as of 2026; long-term human safety profile unknown.

BPC-157 — Research Summary

Recovery / Healing
Human RCT None Animal Extensive
Risk: Speculative

Standalone evidence-critique page for BPC-157: mechanism, animal-evidence landscape, zero human RCTs, Sikiric lab COI disclosure, and 2025–2026 media coverage. Deeper than the guide page.

GHK-Cu (topical)

Skin / Longevity
Human RCT Moderate Animal Supportive
Risk: Low (topical)

Copper-binding tripeptide; collagen synthesis and wound healing support. Topical evidence rests on a handful of small RCTs (Finkley 2007, Pickart) — moderate tier, not strong.

GHK-Cu — Research Summary

Skin / Longevity
Human RCT Moderate Animal Supportive
Risk: Split (topical / injectable)

Two-column evidence breakdown: topical moderate (real data behind cosmetic claims) vs injectable unproven (no human RCTs). Includes 2012 Lorentic RCT details and anti-aging claims analysis.

GHK-Cu — Peptide Page

Skin / Longevity
Human RCT Moderate Animal Supportive
Risk: Split (topical / injectable)

Standalone /peptide/ghk-cu reference page — same peptide framed for cross-comparison navigation with TB-500, BPC-157, and growth-hormone secretagogues.

TB-500 (Thymosin β-4)

Recovery / Healing
Human RCT None Animal Moderate
Risk: Speculative

Actin-binding peptide; cell migration and angiogenesis in animal models. Orphan-drug status for corneal repair; otherwise no FDA approval and WADA-prohibited.

Ipamorelin (CJC stack)

Hormonal / Performance
Human RCT Limited Animal Mechanistic
Risk: Off-label (unvalidated)

Ghrelin-receptor agonist that triggers a pulsed GH release; often stacked with CJC-1295 (a GHRH analogue). Limited human RCTs; dosing and long-term safety unvalidated. WADA-prohibited (S2).

Sermorelin (GHRH 1-29)

Hormonal / Performance
Human RCT Limited Animal Mechanistic
Risk: Off-label (unvalidated)

Synthetic GHRH 1–29 analog; amplifies endogenous GH pulse architecture via GHRH receptor. Pediatric diagnostic-stim-test only on label; no adult efficacy RCTs. WADA-prohibited (S2).

Retatrutide

Metabolic
Human RCT Phase II Animal N/A
Risk: Limited long-term

Triple agonist (GIP / GLP-1 / glucagon); Phase II results show ~24% weight loss. Hype consistently outpaces evidence: no PeptideDecoded standalone page yet — coverage lives in the microdosing article and comparison table.

Selank / Semax

Cognitive
Human RCT Limited Animal Moderate
Risk: Gray-market only

Synthetic nootropic / anxiolytic peptides; most human data comes from Russian-language literature with limited independent replication. No FDA approval; sold via gray-market channels.

WADA Prohibited Peptides (2026)

Compliance
Scope Policy
Risk: Banned in sport

Full WADA 2026 prohibited-peptide list, broken down by S-category (S0 = at all times, S2 = hormones, etc.) for athletes subject to testing. Compliance reference, not a peptide page itself.

Buying Safety (Checklist)

Buyer Guide
Scope Method
Risk: N/A (buyer guide)

Quality / vendor red-flag checklist for anyone considering buying research-use-only peptides. Walks through cGMP, COA verification, third-party testing, and the questions every vendor should answer.

How to Verify Peptide Claims

Research Method
Scope Method
Risk: N/A (research literacy)

Methodology page for evaluating peptide claims yourself: evidence hierarchy, PubMed search strategy, red flags, peer review, COI checks, and a 5-question pre-purchase checklist.

Peptide Safety & Regulation

Regulatory
Scope Framework
Risk: N/A (regulatory)

FDA-approved vs compounded (503A / 503B), July 2026 reclassification context, import regulations, quality tiers, side effects, and a vendor evaluation guide.

FAQ: BPC-157 Human Studies

FAQ
Human RCT None Animal Extensive
Risk: Speculative

Single-question research FAQ targeting "Is BPC-157 backed by human studies?" Evidence hierarchy table, GI / musculoskeletal data split, and honest verdict.

FAQ: "Research Use Only" Peptides

FAQ
Scope Regulatory
Risk: Regulatory context

Standalone FAQ: what does "research use only" mean legally? Covers FDA drug vs supplement vs compounding exclusion, cGMP / inspection / approval, LegitScript compliance patterns, and what buyers should verify.

Educational Only — Not Medical Advice

This is a research summary dashboard, not medical advice. PeptideDecoded does not sell peptides, recommend vendors, provide dosing protocols, or make claims about safety or efficacy for any specific individual.

Work with a qualified physician who can evaluate your full medical history, current medications, and individual risk factors before making any decision about peptides — whether FDA-approved, compounded, or sold as research chemicals.
