Our research catalog

The peptides researchers reorder most — every lot is identity- and purity-confirmed twice, the second pass by an independent, US-based ISO/IEC 17025 lab, then traced from synthesis to the vial in your hand.

Yes. We document research-use sales, so you’ll create a free account and confirm you’re a qualified researcher (21+) before checkout. It takes about a minute.

Every product is a research-grade reference compound for in-vitro and laboratory research only — not for human or veterinary use. Handle with standard lab PPE. They are not drugs, supplements, or cosmetics.

No. These are research-grade reference compounds, not approved by the FDA for therapeutic, diagnostic, or veterinary use. We’re upfront about the regulatory category we sit in — and the ones we don’t.

Every lot is third-party tested by an independent, U.S.-based ISO 17025–accredited lab for identity (LC-MS) and purity (HPLC ≥99%). The full COA travels with every order. Deeper method detail is on our Quality page.

These are lyophilized research powders in sealed, lot-coded vials — not sterile-filled injectables, so we don’t make a sterility claim. What every lot is screened for is endotoxin (LAL) and microbial contamination (PCR-based) before release. Your batch’s results are reported on the COA in your account.

Orders ship from our U.S. warehouse with tracked FedEx 2-day delivery. Orders placed before 5pm ET dispatch the same business day. We ship within the U.S. only.

Standard tracked shipping is a $14.99 flat rate, and it’s free on orders over $150. You’ll get a tracking link by email the moment your order leaves our facility.

You’ll receive an email with a tracking link as soon as your package ships. Most U.S. orders arrive in 1–2 business days.

A recurring order ships on a schedule you set, with a standing-order discount and free shipping; pause or cancel anytime from your dashboard. One-time orders ship once, with no schedule.

Send a photo of the damaged packaging and the lot number within 7 days of delivery and we’ll re-ship the affected vials free of charge — no return required. Shipping damage is replaced 1:1 from the same batch.
