The people behind Regena Peptides

Regena was started by a group of self-experimenters who had spent years buying research peptides from suppliers with no documentation, no cold chain and no accountability. We built the opposite of that: a small Spanish-based lab where every vial has a batch code, every batch has a third-party COA, and every question gets answered by a human who can actually read the chromatogram.

What started as an internal spreadsheet of "suppliers we trust" became a business the day we realised the spreadsheet only had one row on it — and the vendor on that row eventually disappeared. Rather than chase the next fly-by-night, we set up shop in Marbella, partnered with an ISO-accredited analytical lab, and made an uncomfortably strict rule: nothing ships without a batch-matched COA. Five years and tens of thousands of vials later, that rule has never bent.
