Nexus Laboratory,

Nexus Laboratory mission

Nexus Laboratory exists to supply research peptides and small- molecule research compounds whose analytical chemistry is transparent. Every batch of every product in the catalog is tested by an independent third-party laboratory, and the resulting certificate of analysis is publicly accessible from the product page — no login wall, no request form, no paywall. The company ships within the United States via USPS and processes payments through MoonPay. The catalog is curated — 96 compounds across 14 research areas — not exhaustive, because the bottleneck on growing the catalog is the time required to validate analytical chemistry, not the time required to source raw material.

Verification philosophy

Every Nexus batch passes three independent analytical checks: reverse-phase HPLC for area-percent purity (target ≥98%), mass spectrometry for compound identity (expected versus observed molecular mass), and bacterial endotoxin screening for contamination introduced during synthesis or handling. The testing is performed by external laboratories — not by Nexus. Independence matters because in-house verification carries a structural conflict of interest: the same entity that benefits from a high-purity claim is reporting the data behind it.

Some research-compound vendors publish purity claims without publishing the chromatogram, the mass spectrum, or the lab identity. Some publish certificates of analysis behind a login wall, or only on request. The Nexus model is the opposite — the certificate is the first thing a researcher should see on a product page, and it's signed, dated, and traceable to a specific batch. Read the methodology in full on the Lab Verified page.

Compound categories we supply

The 96-compound catalog is organized into 14 research areas: GLP-1 and metabolic peptides (semaglutide, tirzepatide, retatrutide, cagrilintide and blends); growth hormone secretagogues (GHRH analogs, GHRPs, IGF-family); healing and tissue-repair compounds (BPC-157, TB-500, KPV, LL-37, thymosin alpha-1); cosmetic peptides (GHK-Cu, AHK-Cu, matrixyl); Russian Khavinson bioregulators (15 short tetrapeptide bioregulators); cognitive and nootropic peptides (selank, semax, cerebrolysin, DSIP, P21); longevity and cellular-health peptides (epithalon, FOXO4-DRI, MOTS-c, humanin, SS-31, NAD+); melanocortin peptides, sexual-health research peptides, sleep peptides, mitochondrial-energy compounds, specialty research compounds, oral-format research compounds, and reconstitution solvents. The full reference data for every compound — CAS, molecular weight, sequence, classification — lives in the peptide research database.

Compliance and research-use commitment

All Nexus Laboratory products are sold strictly for in-vitro research and analytical use. They are not pharmaceuticals, are not intended for human consumption or veterinary use, and Nexus does not provide therapeutic, dosing, or medical guidance under any circumstances. Customers are responsible for ensuring their research complies with applicable institutional, local, state, and federal regulations. The full compliance framing is documented in the regulatory disclaimer.
