A searchable index of research peptides.
Structured entries — sequences, chemistry, mechanism and citations — plus long-form guides and the latest news. Reference material only; nothing here is dosing or medical advice.
AOD-9604
AOD-9604 is a synthetic disulfide-bonded fragment of human growth hormone (residues 176-191 plus an N-terminal tyrosine) investigated as an anti-obesity agent that ultimately failed to demonstrate weight-loss efficacy in clinical trials and is not an approved medicine.
Argireline (Acetyl Hexapeptide-8)
Argireline (Acetyl Hexapeptide-8) is a synthetic topical cosmetic peptide modeled on the N-terminus of SNAP-25 that is studied for its proposed inhibition of SNARE-mediated acetylcholine release; it is a cosmetic ingredient, not a drug.
BPC-157
A synthetic pentadecapeptide derived from a sequence found in gastric juice, studied across biochemical, cellular and preclinical repair research.
Cerebrolysin
Cerebrolysin is a porcine-brain-derived mixture of low-molecular-weight peptides and free amino acids studied for purported neurotrophic and neuroprotective effects, approved as a medicine in some countries but not by the US FDA.
CJC-1295 (No DAC)
A modified GHRH(1-29) analogue without the drug-affinity complex, studied as a growth-hormone-releasing peptide in research settings.
Dihexa
Dihexa is a research-only, angiotensin IV-derived oligopeptide studied preclinically as a proposed potentiator of HGF/c-Met signaling and synaptogenesis, with no human data and a key mechanistic paper retracted in 2025.
What Are Research Peptides? A UK Guide
A plain-English guide to research peptides: what they are, how they are studied in the laboratory, and how purity is verified. Research use only.
Are Peptides Legal in the UK? (2026 Guide)
How research peptides are regulated in the UK — the MHRA, the Human Medicines Regulations 2012, what “research use only” means, and importing. General info, not legal advice.
Buying Research Peptides in the UK: What to Check
A buyer’s checklist for research peptides in the UK — Certificates of Analysis, HPLC purity, cold-chain dispatch and supplier transparency. Research use only.
What Is a Certificate of Analysis (COA)?
What a Certificate of Analysis tells you about a research peptide — HPLC purity, mass-spectrometry identity, and how to read one. Research use only.
What public figures actually said about peptides — from Joe Rogan’s BPC-157 story to Huberman’s and Attia’s cautions. Clips are real and sourced; reference only, not endorsement.
