Research-grade peptides
Research peptides you can verify, batch by batch.
FRO Peptides (For Research Only) supplies lyophilized research peptides and coenzymes for laboratory and independent research. The catalog covers the compounds researchers ask for most, including BPC-157, TB-500, GHK-Cu, semaglutide, tirzepatide, retatrutide, ipamorelin and NAD+.
"Lab-verified" should mean something you can check. Each lot is tested by an independent lab, AccuMark Labs, for HPLC purity and compound identity, and the certificates are published in our COA Library with the lot number, test date and purity result, not just "available on request." Product pages link straight to the certificate for the batch you are buying.
Peptides are supplied strictly for laboratory and analytical research. They are not for human or veterinary use, and we do not provide dosing or usage advice.

Common Questions.
Everything you need to know about our synthesis process, laboratory verification protocols, and research utility.
Are your compounds intended for human use?
All products sold by FRO Peptides are strictly for laboratory and analytical research purposes. They are not intended for human or veterinary use, consumption, or clinical application of any kind.
How do I verify the purity of a compound I've ordered?
Every batch ships with a corresponding Certificate of Analysis (CoA) documenting purity, compound identity, and testing parameters. CoA documentation is available upon request for any order, and every published certificate is in our COA Library.
What is your sourcing and quality control process?
Each compound is sourced through a controlled supply chain and undergoes internal quality verification before fulfillment. We maintain batch-level traceability from sourcing through final packaging to ensure consistency across every order.
Do you offer bulk or volume pricing for research institutions?
Yes. Volume discount codes are available for qualifying orders. Researchers ordering at scale can reference our discount structure at checkout — no separate application required.
What are your shipping and handling standards for research compounds?
Orders ship from our California fulfillment center by FedEx 2-Day at a $9.95 flat rate, and usually arrive about 2 business days after they ship. Compounds are packaged to maintain integrity during transit. Orders over $200 qualify for free shipping.
