Peptide Pump is an independent reference covering the published research literature on peptides studied in the contexts of skeletal muscle hypertrophy, soft-tissue repair, and recovery from athletic training. It is written for serious researchers, coaches, and athletes who want primary-source depth instead of supplement-shop marketing.
Skeletal Muscle Growth
The GH/IGF-1 axis, mTOR signaling, satellite-cell activation, and the published peptide literature relevant to skeletal muscle protein synthesis.
Read briefTissue Repair & Recovery
BPC-157, TB-500, GHK-Cu in the soft-tissue repair literature: animal-model dominance, the limited human data, and where the gaps are.
Read briefInjury Prevention
Tendon, ligament, and joint research. Where peptide research overlaps with the orthopedic and sports-medicine literature.
Read briefBody Composition & Fat Loss
The lipolytic peptide literature: AOD-9604, GHRP-pairings, tesamorelin trial data, and what does (and does not) survive replication.
Read briefCycling & Receptor Theory
Desensitization data for GHRH and ghrelin-mimetic compounds; how researchers structure on/off windows to preserve response curves.
Read briefWADA & Competition Status
Anti-doping classification of common research peptides, in-competition vs. out-of-competition rules, and washout considerations.
Read briefCompound Profiles
Each profile reviews the primary research literature for a single compound: mechanism, animal-model data, the (often more limited) human evidence, documented dosing ranges, half-life data, side-effect profile, and the gap between mechanistic promise and replicable clinical outcomes.
| Compound | Class | Best-documented Application | Evidence Base |
|---|---|---|---|
| BPC-157 | Pentadecapeptide | Soft-tissue repair | Animal-model dominant |
| TB-500 / TB-4 | Thymosin fragment | Wound healing · cardiac repair | Animal + limited human |
| CJC-1295 + Ipamorelin | GHRH-analog + GHS | GH/IGF-1 modulation | Human pharmacology |
| Sermorelin | GRF(1-29) | GH-deficiency therapy | FDA-approved (historic) |
| AOD-9604 | hGH 176-191 fragment | Lipolysis (limited) | Trial-stage |
| GHK-Cu | Copper tripeptide | Skin / wound healing | Extensive cosmetic; limited systemic |
| Epithalon | Tetrapeptide | Telomerase activation (claimed) | Russian dominant; limited Western |
How To Use This Reference
Every brief on Peptide Pump is structured the same way: a clear research question, a review of what the literature actually says, the methodological caveats, and reference dosing ranges drawn from primary sources. The aim is to make the boundary between well-studied, provisionally studied, and marketing claim as obvious as possible.
Where to start:
- New to the research literature? Begin with the Reference First Cycle — it walks through the most-studied entry-level protocol and the markers researchers track.
- Interested in a single compound? Jump directly to its profile page; profiles are self-contained and cite primary literature throughout.
- Looking for context across multiple compounds? Read the stack-literature brief or the cycling-theory brief.
- Subject to anti-doping testing? Start with WADA status before reading anything else.
Editorial Standards
Peptide Pump is independently produced and editorially independent. We do not sell products, accept paid placement, or hold any vendor affiliations. Citations are primary literature wherever possible (PubMed-indexed journals); when only conference abstracts, preprints, or self-reports are available, we say so.
The peptide research base evolves quickly and is unevenly funded across compounds. Some compounds covered here have robust human pharmacology; others rest on animal models and a small body of replication. We make those distinctions explicit on every page.
For a full description of how we work and what we don’t do, see the about page. For the regulatory framing of every compound we cover, see the terms of use — in particular, the research-chemicals disclaimer.
Every compound on this site is a research chemical. Nothing here is medical advice, a recommendation for personal use, or an endorsement of athletic-performance applications. Many of these compounds are prohibited in tested sport under WADA codes. Consult a licensed physician before considering any compound covered here.
