About Peptiva
A research-materials brand built on documentation.
Peptiva Pharmaceuticals is a UK-based supplier of peptide research materials. The current range is a set of pre-filled research pens — Retatrutide, Tesamorelin, Recovery Plus, MOTS-C and Glow — with nasal and vial formats to follow. Our approach is simple: print the facts on the carton, repeat them on the website, make every batch checkable, and describe the science without exaggeration.
What we publish
Everything printed on the carton — composition, total strength, storage conditions, batch number and expiry — is reproduced on each product page. Where the carton does not state a per-ingredient split, we say so rather than estimate.
How we describe research
Each compound is described in plain English: what it is, and what published research investigates. We separate preclinical (cell and animal) findings from human evidence, and we do not claim health benefits, clinical results or regulatory approvals.
Verification
Every carton carries a batch number and a scannable verification code that resolves on this website. Certificates of Analysis for released batches are available on request by email.
Research use only
Peptiva materials are supplied strictly for laboratory and in-vitro research. They are not medicines, supplements or cosmetics, and are not for human or animal use.
