The Fitpeptides Guarantee

Every batch is independently verified and documented — so you know exactly what you are working with.

Every batch is tested by an ISO 17025-accredited laboratory before it ships. The report is signed, dated and attached to your order so you can verify identity and purity against your own protocols.

A batch-specific Certificate of Analysis accompanies every shipment — HPLC-UV/VIS purity, mass-spec identity and endotoxin values. Batch and lot numbers are published openly.

The whole chain, from production to your door, is kept cold for optimal peptide stability. Orders are tracked end to end and replaced if lost or damaged in transit.

All peptides ship as lyophilised powder for maximum shelf life and purity. Compounds that fail our purity standard never reach the catalogue.

TB-500 + BPC-157

Very happy with the BPC-157 and TB-500. Discreet packaging and good customer service. The only reason for four stars is that I would like more payment options.
