The evidence-based
reference for research peptides
Mechanisms, protocols, PubChem data, and clinical evidence — written in plain language with the full technical reference underneath. Built for informed consumers who want the truth, not the hype.

How we read the science
What makes this reference different
01 · Layered
Plain language first, full reference underneath
Every peptide page opens with a 60-second “In Brief” summary, then expands into the full technical record — sequence, mechanism, evidence, protocols.
02 · Primary
Citations link to PubMed and PubChem
Every specific claim ties back to a primary source — peer-reviewed literature, NCBI, PubChem. No screenshots of summaries, no recycled marketing copy.
03 · Honest
Uncertainty is named, not hidden
Preclinical animal data is not the same as a human clinical trial. We say so. When the evidence is thin, the page says so — in plain English.

Common questions
Frequently asked
What is a peptide?
A peptide is a short chain of amino acids — the same building blocks that make up proteins, but joined in much shorter sequences. Naturally occurring peptides include insulin (51 amino acids) and glucagon (29). Most research peptides on this site are 3–30 amino acids long. The distinction from a protein is fuzzy, but peptides are typically under 50 amino acids and don’t fold into the complex three-dimensional structures that proteins do.
Are research peptides legal?
It depends entirely on the peptide and jurisdiction. Some peptides have approved human pharmaceutical versions (semaglutide, liraglutide, tesamorelin) and are legal by prescription. Most peptides discussed here — BPC-157, TB-500, melanotan, GHK-Cu, and others — are not approved for human use in the United States, the European Union, or most other jurisdictions, and may be classified differently across borders. Many are banned in competitive sport by WADA. This site is reference material only; it does not advise on legality or use.
Why no human dosing protocols?
Because the published clinical-trial data for most research peptides is thin or absent. We list the dose ranges used in preclinical (animal) studies because that’s what the literature shows, but human equivalent doses cannot be safely extrapolated from rodent doses. Publishing “recommended human protocols” for unapproved compounds would misrepresent what the evidence actually says. Anyone serious about peptide research should work with a qualified physician and an IRB, not a website.
How do you decide what evidence to include?
Primary literature first — peer-reviewed studies indexed in PubMed, with preference for the original research papers over reviews of reviews. Each peptide page’s Evidence Summary describes representative findings and links to PubMed. We note the source institution where a single group has produced most of the work (so you can judge replication risk), and we flag where human trials are missing versus where they exist but are small.
Is this medical advice?
No. Nothing on this site is medical advice or a recommendation to use any peptide. If you’re considering anything described here for your own health, talk to a qualified healthcare professional.
