Verified Pure Peptides

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:

• Purity levels to confirm high-grade peptide composition
• Net peptide content per vial for accuracy
• Endotoxin (lipopolysaccharide) presence to ensure safety
• Sterility testing for bacterial and yeast contamination

Our commitment to precision and safety guarantees that every peptide meets stringent quality standards, delivering reliable and effective results.

We offer some of the most competitive pricing on the market with rates up to 30% lower than the industry average. Our tiered pricing ranges from an additional 5% to 25% off and more for wholesale.

Orders ship the same day if placed before 1PM EST or the next day if placed after. Orders over $200 qualify for free Fedex 2-Day shipping. We also offer an insulated shipping option with a styrofoam lining and a large ice pack.
Other couriers are available upon request (USPS or UPS).

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%.

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.

We offer a wide range of oligopeptides and polypeptides suitable for a variety of fields in peptide research. Our quality control and guarantee assures your research materials are consistent and reliable.

If you’re interested in a custom peptide not found in our catalog, send us an email with the details of your request including the name and CAS number of the peptide. Customization of peptide blends and weight per vial are available.
