Frequently asked questions

Reconstitution refers to the laboratory process of preparing a lyophilized (freeze-dried) peptide by adding a liquid solvent in order to create a solution for research use. Lyophilization helps preserve peptide stability during storage and transport.

A Certificate of Analysis (COA) is a laboratory-issued document that verifies the identity, purity, and quality of a compound. COAs are generated using analytical testing methods such as High-Performance Liquid Chromatography (HPLC) or mass spectrometry.

We provide COAs to ensure transparency and to allow researchers to confirm that each product meets its labeled specifications before use in laboratory research.

Purity refers to the percentage of the vial that contains the intended peptide compound versus residual solvents, synthesis byproducts, or impurities.

At Pure Source Peptide, we only sell peptides with a purity of 99% or greater. This standard:
• Supports reliable and reproducible research outcomes
• Minimizes unwanted variables in experimental models
• Reflects rigorous manufacturing and quality control standards

Maintaining high purity is a core part of our commitment to supplying research-grade compounds.

All products sold by Pure Source Peptide are designated Research Use Only (RUO) and are therefore labeled “Not for Human Consumption.” This designation means the compounds:
• Are not approved by the U.S. Food and Drug Administration (FDA) for human or veterinary use
• Have not undergone clinical safety or efficacy evaluation
• Are not intended to diagnose, treat, cure, or prevent any disease

Due to the nature of research chemicals, all sales are final once an order has been shipped. We encourage customers to review product details, storage requirements, and regulatory considerations prior to purchase.

No. Our products are not approved by the U.S. Food and Drug Administration (FDA). They are sold strictly as research compounds and are not intended for human or veterinary use.
