Research Peptides
Research peptides from NeoPep are synthesized in the USA and verified to ≥99% purity by independent laboratories before any lot is released to researchers around the country. Laboratories running tissue-repair and metabolic studies choose us for BPC-157, TB-500, CJC-1295, Ipamorelin, Sermorelin, and Retatrutide.
Every compound ships with a batch-specific Certificate of Analysis documenting identity, purity, potency, and endotoxin results for the specific material in your vial, from your first order onward, so your peptide research starts from verified material.
BROWSE RESEARCH PEPTIDESThe quality standard every research peptide is held to.
≥99% minimum purity
Lots that fail the purity threshold are rejected outright. There is no release-on-appeal.
Identity confirmed by LC-MS
Mass spectrometry confirms the molecular sequence of every released lot.
Endotoxin testing
Every lot is screened for endotoxins before it is cleared for dispatch.
Lyophilized, cold-packed
Compounds ship lyophilized in insulated, light-protected packaging for stability.

Frequently asked questions
What are research peptides?
Research peptides are short-chain amino acid compounds supplied for in-vitro laboratory study, from peptide hormone signaling to tissue repair. They are not intended for human or veterinary use.
How do I verify the quality of research peptides?
Request the batch-specific Certificate of Analysis, confirm testing was performed by an independent lab, check that the company lists a physical address, and verify that identity (LC-MS) and purity (HPLC) are each reported as separate results.
Do you sell blends or only single compounds?
Both. Our catalog includes single compounds such as BPC-157 and Retatrutide, and research blends such as Wolverine (BPC-157 / TB-500) and CJC-1295 / Ipamorelin. First-time customers can ask our support team for help choosing the right compound.
FOR RESEARCH USE ONLY
All research peptides are supplied strictly for in-vitro laboratory research by qualified professionals. Not for human or veterinary use. Not intended to diagnose, treat, cure, or prevent any disease.
