Claripep was founded in 2026 as a UK-based supplier of research-grade peptide compounds, built around a simple idea: researchers deserve genuine, independently verified proof of what they’re buying — not a generic certificate copied across every batch a supplier ships.
Why We Started
The research peptide market has grown quickly, but verification standards haven’t kept pace. Many suppliers provide a Certificate of Analysis, but it’s often a template recycled across multiple batches, or sourced from a lab with no independent standing — meaning the document exists, but doesn’t actually tell a buyer much.
We built Claripep around the opposite approach: every batch we sell is tested independently by a third-party laboratory before it’s ever listed, with the COA published openly alongside the product. If a result doesn’t meet our standard, the batch doesn’t go up for sale. That’s the whole model.
What We Do
Claripep sources research-grade peptide compounds from established manufacturers, verifies every batch independently, and supplies them to UK researchers, laboratories, and institutions — strictly for laboratory research use.
We are not a pharmacy, a clinic, or a healthcare provider. We do not make claims about human or animal outcomes, and we do not provide dosing or administration guidance, because our products are not approved or intended for that purpose. Our role is to be a reliable, transparent, properly verified supplier for the research community.
Our Standards
Every product listed on this site is accompanied by:
- A batch-specific Certificate of Analysis from an independent testing laboratory
- HPLC purity verification
- Mass spectrometry identity confirmation
- Heavy metal and endotoxin screening, where applicable
We publish this documentation openly because we believe it should be the baseline expectation in this industry, not a premium feature.
Compliance
All products supplied by Claripep are intended strictly for in vitro laboratory research purposes. They are not for human or veterinary consumption, and have not been evaluated by the MHRA, FDA, or any other regulatory body for safety or efficacy in humans or animals. We require all customers to confirm they are purchasing for genuine research purposes.
