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.
Pre-Mixed vs Lyophilised Peptides: What the Difference Actually Means
Pre-mixed solution or freeze-dried powder — how the two formats differ on stability, shipping, shelf life and handling error, and which UK suppliers ship which. Reference material only.
GLP-1 Peptide Storage, Cold Chain and Handling
How GLP-1 receptor agonist peptides — semaglutide, tirzepatide, retatrutide — are handled in laboratory and supply settings: cold chain, excursion tolerance, and in-solution stability. Reference material only.
What Is NAD+? (And Is It a Peptide?)
NAD+ explained for researchers: what the coenzyme is, why it is not a peptide, the metabolic pathways it is studied in, and how the NR and NMN precursors relate to it. Research use only.
How to read this index
What each part of a peptide entry means — the fingerprint, the property table, statuses, and how search works.
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.
