Where Science Meets the Skyline

For Research Use Only

Research peptides you can actually verify.

A hard 99%+ purity floor, third-party batch tested, with a lot-matched Certificate of Analysis on request. Built in Miami, shipped nationwide.

The difference

Most suppliers ask you to take purity on faith. We hand you the paperwork.

We’ll be straight with you: we’re not the cheapest peptides you’ll find online. We’re the most documented. Every batch is analyzed by an accredited third-party lab, and the report is tied to the exact lot in your hands.

  • HPLC purity, MS-confirmed identity — a 99%+ floor on every compound.
  • Endotoxin tested — < 0.25 EU/mg by accredited LAL assay.
  • Lot-matched COA — the certificate matches your batch, not a sample vial.

Why researchers choose Biscayne Science

Three promises, each one you can verify.

Purity you can check

A hard 99%+ purity floor, with a third-party Certificate of Analysis available on request — batch and lot documented.

Independently lab-tested

Every batch is analyzed by an accredited third-party lab for identity, purity, and endotoxin — not self-reported.

Shipped on a real timeline

Orders ship within 7 business days of confirmed payment, tracked end to end.

Our guarantee

The Biscayne Purity Promise

Research compounds are sold as final sale — but you’re never stuck with a vial that isn’t right. Here’s what we stand behind on every order.

Fails QC? We replace it

Any vial that fails QC verification against its Certificate of Analysis is replaced from a passing batch — material that matches the paperwork.

Arrives damaged? We replace it

Every vial ships as a stable lyophilized powder, cushioned in Type I borosilicate glass — and if one still arrives damaged, send a photo and we replace it.

Tracked to your bench

A tracking number is sent the moment your order ships — so you always know where it is.

Don’t see the peptide you’re looking for?

Our catalog is always expanding. If there’s a research compound you need that isn’t listed here, send us a message and we’ll see what we can source for you.
