Research-grade reference materials, documented lot by lot
Research Peptides LLC is a US supplier of peptide reference materials sold to academic, institutional and commercial laboratories for in-vitro laboratory research. We supply the compounds listed in our catalog, the documentation that accompanies each production lot, and direct support for laboratories that need a quote, a specification or a specific record.
This page explains what we supply, how each lot is documented and verified, the conditions under which orders are accepted, and how to reach our team. Every visitor sees this same information.
For Research Use Only — Not for Human Consumption.
What we supply
Everything we sell is a chemical reference material in the quantity stated on its catalog page. We describe compounds by their chemical class and the receptor or pathway they are used to study. We do not describe health outcomes, and none of these items is a drug, supplement or product for personal use.
Incretin receptor agonist peptides
GLP-1, GIP and glucagon receptor agonist sequences, including semaglutide, tirzepatide and the RT-3 series, supplied as lyophilized powder in 10 mg to 50 mg quantities.
Growth-hormone secretagogue and GHRH analogs
Sermorelin, tesamorelin, CJC-1295 and ipamorelin, supplied for receptor-binding and secretory-pathway studies in vitro.
Tissue-repair and matrix peptides
BPC-157, the TB-500 fragment, GHK-Cu, AHK-Cu and KPV, offered individually or as co-lyophilized blends (GLOW, KLOW).
Mitochondrial and coenzyme reference compounds
NAD+, MOTS-c, ARA-290 and glutathione, supplied as assayed powders for cellular and biochemical study.
Additional single-sequence peptides
Melanotan II, IGF1-LR3 and a small number of proprietary blends, each described on its own catalog page.
Laboratory reagents
Bacteriostatic water (0.9% benzyl alcohol, 30 mL) for reconstitution of lyophilized material in the laboratory.
Independently verified batch documentation
Every production lot is assigned a lot code printed on the vial label. That code ties the vial to a certificate of analysis issued by an independent analytical laboratory, which reports identity confirmation by LC-MS and purity by HPLC-UV, together with the method, column, wavelength, retention time and peak area recorded for that lot.
We publish the figures a laboratory reports for a specific lot. We do not publish estimated, averaged or illustrative values, and this page deliberately carries no purity figure of its own — the certificate for your lot is the record that applies. If a lot's certificate has not yet been issued, we say so and send it once the laboratory releases it.

How to read a certificate
What the identity and purity figures mean, and how to check a lot code against its report.
Lot records are retained against the order they shipped with. Handling and storage notes specific to a lot are printed on its certificate.
Who we supply, and what we do not do
Orders we accept
- Qualified researchers at academic, government, institutional and commercial laboratories.
- Laboratories and businesses requesting bulk quantities, a standing supply or technical documentation.
- Buyers who complete the researcher verification step at checkout, including institution, role and intended laboratory use.
We do not provide
- Human or veterinary consumption of any kind, including self-administration or dosing.
- Medical, therapeutic, diagnostic or compounding use, or advice on any of these.
- Personal use: our compounds are not supplements, cosmetics or consumer products.
- Any claim that a compound treats, prevents or improves a health condition — we make none.
Orders that cannot be verified as laboratory purchases may be declined and refunded. Payment instructions, shipping terms and the research-use conditions are set out in the terms of sale.
