The Peptide Compound Guide: Every Compound in Plain English
New to peptides? What each compound in the catalog is, the pathway researchers study it in, and where it fits — grouped by research area, jargon translated.
Batch Traceability: Which Lot Is This?
Lot → third-party COA → lab-portal verify. How to fail a seller who skips a link in the chain.
BPC-157 Research Reference
Identity and COA verification for BPC-157 research material — not a shop clone, not a protocol.
TB-500 Research Reference
How to read a TB-500 listing: price snapshot, assay trail, research-use framing.
GHK-Cu Research Reference
Catalog identity and verification only — deliberately free of cosmetic or outcome language.
Ipamorelin Research Reference
Single vial or research bundle; 10-vial kits are wholesale. COA literacy and RUO identity without secretagogue outcomes.
MOTS-c Research Reference
Dual stock lanes, COA path, and RUO identity — distinct from the What Is MOTS-C explainer.
Tesamorelin Research Reference
Kit strengths, lot-matched COAs, research-use framing — no Rx/outcome language.
NAD+ Research Reference
Multi-strength listing identity and verification literacy. The public shop sells a single vial or a research bundle; 10-vial kits are wholesale. Deliberately free of anti-aging claims.
Peptide Sciences Shut Down (2026): What Happened
The largest US research-peptide vendor closed in March 2026. What's confirmed, what isn't, and how to vet a supplier now — verify the batch, not the brand.
