Peptides
Shop research peptides for sale from Peptide Technologies — one of the deepest research peptide catalogs available, spanning single-compound reference materials such as BPC-157, TB-500, GHK-Cu, and the secretagogue and metabolic families. Each product is a research-grade reference standard characterized by HPLC and backed by a public, batch-specific Certificate of Analysis. Whether you are sourcing a well-characterized compound for a laboratory model or comparing purity across suppliers, every listing below documents identity, purity, and lot traceability so your procurement decisions rest on evidence, not marketing.
What you'll find in this category
The Peptides category collects our single-compound research materials — the individually characterized peptides used as reference standards in laboratory research. Popular research targets include BPC-157, TB-500 (thymosin beta-4 fragment), GHK-Cu, and members of the growth-hormone secretagogue and incretin families. Multi-compound stacks live under Peptide Blends, and oral-format reference materials under Capsules.
Each product page lists the compound's molecular identity (formula, molecular weight, sequence where applicable), the available strengths, and the current batch COA. Where a compound is offered in several strengths, an on-page selector links the sibling reference standards so you can compare specifications side by side.
How we verify purity and identity
Every batch is analyzed by an independent, accredited US laboratory and ships with a QR-linked Certificate of Analysis (COA) verifying identity and purity by HPLC. All items are supplied strictly as reference materials for laboratory research. Not for use in humans or animals.
Our purity documentation is the reason researchers choose us: no product is listed until its batch clears a full analytical panel — identity, purity, net content, and conformity — at an accredited laboratory, and the resulting certificate is published and QR-linked to the vial. This is what lets you audit any lot before and after purchase.
Frequently asked questions
- What are research peptides?
- Research peptides are short chains of amino acids supplied as reference materials for laboratory research. In this catalog each is characterized for identity and purity and documented with a third-party Certificate of Analysis. They are sold strictly for in-vitro and non-clinical laboratory research and are not for use in humans or animals.
- Do your peptides come with a Certificate of Analysis?
- Yes. Every batch ships with a QR-linked, batch-specific COA from an independent accredited US laboratory, verifying identity and HPLC purity. You can view the certificate on each product page and by scanning the vial's QR code, which links to our public COA library.
- What purity are your research peptides?
- Purity is reported per batch on each COA and is typically 98% or greater by HPLC. Because we publish the certificate for the specific lot you receive, you can confirm the exact figure rather than relying on a generic claim.
- Where are your peptides made and how are they shipped?
- Our research materials are filled, finished, and tested in the United States. Orders ship from the US with cold-chain handling appropriate to the material. Products are supplied for laboratory research use only.
- How should research peptides be stored?
- Lyophilized (freeze-dried) research peptides are generally stored cold and protected from light until reconstitution with a suitable laboratory diluent such as bacteriostatic water; storage guidance for each material is intended for laboratory handling only. See the individual product page for the material's storage note.
