Origen Scientific is a US-based supplier of research peptides — started by researchers who were tired of taking a label's word for it.
This industry runs on trust that's rarely backed by documents. We built Origen to work the other way around: every batch is tested by an independent U.S. laboratory — identity, purity, net content, endotoxin, and microbial screening — before a single vial ships.
You don't have to take our word for anything. The paperwork exists, and it's yours on request.
Every compound we sell carries a >99% purity specification, verified per batch by HPLC. If a batch ever tests below that, we replace it or refund you in full. We'd rather lose an order than ship a number we can't stand behind.
We document material — never outcomes. If we can't prove a claim, we don't make it. If it isn't proven, it doesn't ship.
Orders confirmed before 2 PM ET ship the same day from US-based fulfillment. Free shipping on orders over $250.
Encrypted checkout with a simple reserve-then-pay flow. Pay whichever way suits you:
Questions on a product, a batch, or your documentation — email us and a person answers. Every order is covered by the 30-day purity guarantee.
