Every batch is third-party tested by independent U.S. laboratories. We guarantee 99%+ purity on all research peptides with full COA documentation available for every product.
Yes! Unlike cheap Chinese peptide companies, peptide.co ships out of the United States.
Our peptides are manufactured in FDA-registered facilities that maintain strict quality control standards and follow current Good Manufacturing Practices (cGMP).
Every batch is produced to the highest level of purity, consistency, and compliance with U.S. regulations. Additionally, all products undergo third-party testing by independent U.S.-based laboratories to verify their quality and potency before shipping.
Orders ship the day after your order is placed. Our free shipping for orders over $200 use UPS Air, but speedier options like UPS Express are available. We also offer an insulated shipping option with a styrofoam lining and an ice pack.
Other couriers are available upon request (USPS or Fedex).
Our checkout process is as straightforward as any other. Add a peptide(s) to your cart, fill out your shipping and billing information, and complete your checkout with a standard credit card payment.
We maintain the highest standards for quality and purity by manufacturing our research peptides in a GMP facility, ensuring strict adherence to Good Manufacturing Practices (GMP).
Each batch undergoes rigorous Quality Control (QC) testing to verify purity, potency, and safety. We partner with trusted analytical testing laboratories to assess:
Our commitment to precision and safety guarantees that every peptide meets stringent quality standards, delivering reliable and effective results.
Peptides in lyophilized powder form (unreconstituted) should be stored at freezer temperatures of 17°F (-8°C) to -4°F (-20°C) for long term storage of 1-2+ years for minimal degradation.
Reconstituted peptides should be refrigerated at 36°- 42°F and should be stable for at least 1-2 months or more.
Our peptides are in lyophilized (freeze-dried) vials. Lyophilization is a process that significantly increases the stability and shelf life of compounds. Short term temperature variations during transit times will not affect the integrity of the peptide and should still keep purity at 99%.
