Research peptide vendor
A US-based research peptide vendor selling under F2 Nutrition, with an unusually large public certificate-of-analysis library and open pricing, positioned entirely as a research-use-only supplier rather than a consumer health brand.
quality claims we could confirm ourselves, rather than repeat from the vendor's marketing.

$55.97Every product here is sold under a Research Use Only policy, administered by F2 Nutrition, doing business as BioLongevity Labs. Read that as a real gate, not boilerplate. At checkout, the buyer attests the purchase is for laboratory or in vitro research. They consent to IP verification of that claim. They agree to submit at least one study or research result annually just to keep their account active. None of this is a legal consumer product, and nothing on the vendor's site, or on this page, suggests it should be used as one.
Graded by whether we could confirm it ourselves or are only repeating what the vendor states. A vendor's honesty about its own testing is a different question from what a published trial shows, so this is a separate scale from the evidence grades on our guides.
This is the vendor's own description of its process, repeated on its homepage and about page. We did not contact the three labs to confirm their certification or their independence from the manufacturer, and nothing on the site names which labs those are.
Where the vendor states thisThis number is printed on every product page we checked, including BPC-157 and GHK-Cu. We did not open the underlying Certificate of Analysis ourselves to check the raw chromatogram against the stated figure.
Where the vendor states thisStated on the vendor's about page. We did not cross-check this against the American Peptide Association's own membership list.
Where the vendor states thisWe opened this ourselves. Every catalog product, including single-vial peptides and blends, is listed and searchable without creating an account. That is meaningfully more transparent than most vendors in this category, where a COA is either not offered or is emailed only after purchase.
Where the vendor states thisDirectly observed across every product page we checked, including the bulk-quantity discount tiers.
Where the vendor states thisThe site credits a board-certified physician as scientific reviewer of its content, which is a genuine credibility signal. It does not name the three labs it says perform independent testing, so a reader cannot look those up directly.
Per the vendor's own policy, opened products cannot be returned at all, and unopened returns carry a 15% restocking fee plus return shipping. That is standard for the category given the regulatory framing, but it means there is effectively no way to recover the cost of an order once it ships.
The policy states the buyer consents to IP address verification and agrees to submit research results annually to keep their account active. Read that policy before ordering, not after.
As a company, yes. It's a registered US business, F2 Nutrition, doing business as BioLongevity Labs. It publishes a physical return address and phone contact, credits a named board-certified physician as scientific reviewer, and maintains a public COA library. That's a more transparent setup than most vendors in this category. But it's still an unregulated research-chemical seller. Not a licensed pharmacy. Nothing it sells is an approved consumer product.
Every fact above traces to one of these pages, published by the vendor itself and checked on September 11, 2026. Vendor policy pages change without notice, so if something here looks out of date, it probably is.
