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.
  • Sterility tested — each batch is tested for sterility.
  • Lot-matched COA — the certificate matches your batch, not a sample vial.

Research documentation covers each published compound note, lot-matched certificates, HPLC, and endotoxin.

Our guarantee

The Biscayne Purity Promise

Refunds are only for unopened, factory-sealed vials returned within 14 days of delivery. Here’s what we replace 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. If one arrives damaged in transit, email info@biscaynescience.com within 7 days of delivery with your order number and photos. We replace it. That replacement is not a refund.

Tracked to your bench

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