Featured Products
Every product independently tested. COA included with every order.
Every Batch.
Every Time.
No Exceptions.
Most peptide suppliers skip third-party testing or bury results where no one looks. Petratide Science publishes a batch-specific Certificate of Analysis with every single product — before it ever ships to you.

In an industry full of shortcuts, Petratide was built to set a higher standard. We prioritize authenticity, affordability, and transparency so researchers can trust the materials they work with.
Beyond our products, we’re building a community of researchers who value honesty, accountability, and open communication. Petratide exists not just to supply peptides, but to support a transparent research environment where quality and trust come first.

FREQUENTLY ASKED QUESTIONS
What are peptides?
Peptides are short chains of amino acids that act as signaling molecules in many biological systems. They are commonly studied in laboratory research to better understand cellular processes and biological communication.
What does Research Use Only mean?
Research Use Only (RUO) means the materials are intended strictly for laboratory research and analytical purposes. They are not approved for human or veterinary use and are not intended for diagnosis or treatment.
Do you provide Certificates of Analysis (COAs)?
Yes. Certificates of Analysis are provided when available and include information such as purity, testing methods, and batch identification to help verify analytical results.
How should research materials be stored?
Most lyophilized peptides should be stored in a cool, dry environment and protected from light. Many researchers choose refrigerated or freezer storage to help preserve stability.
How quickly are orders processed and shipped?
Orders are typically processed promptly and shipped from within the United States. Delivery times may vary depending on location and shipping method selected at checkout.
