Proba Research
Research peptides with the paperwork to match
Proba Research supplies laboratory-grade peptides and research compounds to the UK research community. Every product is HPLC-tested and supplied with a downloadable certificate of analysis, so you can check what is in the vial before you order it.
- Lab report with every batch
- 3rd-party tested
- ≥99% HPLC purity spec
Built for researchers who read the certificate first
A peptide is only as useful as the documentation behind it. That is why every compound in our catalogue carries its own certificate of analysis as a downloadable PDF, covering identity and purity testing. No certificate, no listing.
Our range spans five research categories: cellular, neural, metabolic, endocrine and tissue research. Each product page states the formats and vial sizes available for that compound, with larger formats sold as variants of the same product, so laboratories can order the quantity a protocol actually needs.
What you can check before you buy
Certificates on every product
Each product page links to its certificate of analysis. Download it, read it, and compare it against the vial that arrives.
Traceable sourcing
Every compound is sourced through our manufacturing partner and arrives as lyophilised powder in sealed vials, matched to the certificate of analysis on its product page.
HPLC purity testing
Purity is verified by high-performance liquid chromatography. The figure on the certificate is the figure that matters.
Research use only
Every product is sold strictly for in-vitro and laboratory research. Nothing we sell is for human or veterinary use, and our packaging, labelling and copy say so plainly.

Guaranteed, in writing.
Every vendor says pure, tested, safe. We publish the paperwork that proves it and put our name on the batch.
The report before the sale
Every production batch is tested by an independent laboratory and the certificate is published before the batch is offered.
The floor is ≥99% HPLC
A standing specification on every compound we list, not an aspiration or an average across runs.
Sealed and tracked
Room-temperature-stable packaging, sealed at the facility, tracked from the moment it leaves.
Made here
Synthesised and lyophilized in US-based cGMP facilities under documented process controls.
