Our Company

Factor Peptides is a USA-based manufacturer dedicated to producing the highest-purity research peptides available on the market. Founded by a team of biochemists and research scientists, our mission is simple: give researchers reliable, consistent compounds they can trust. Every product we ship has been synthesized, tested, and verified in our state-of-the-art facility before it ever leaves our doors.

Our manufacturing process adheres to strict quality-control protocols at every stage — from raw amino acid sourcing through final lyophilization and packaging. Each batch is independently analyzed by HPLC and mass spectrometry to confirm sequence identity and purity levels exceeding 99%. We believe that in research, the integrity of your starting materials determines the integrity of your results.

We are committed to fast, discreet fulfillment. Orders typically ship within 24 hours via 2-day express, with free shipping on qualifying orders over $200. Our customer support team is available to assist with product questions, documentation requests, and order inquiries. We look forward to supporting your research.
