THE CERTIFICATE
IS THE PRODUCT.

A peptide is only as good as the paperwork that travels with it. Most paperwork in this market is one generic PDF shared across every batch ever sold. Ours is dated, per batch, per test — and it stays on file after the batch sells through.

RESEARCH USE ONLY.
NOT FOR HUMAN USE.

1What we make

Lyophilized research peptides, sterile reconstitution vehicles and laboratory supplies. Small batches, synthesized to order where we can, tested on intake, and labeled with the batch code that resolves to its own certificate. No drop-ship relabeling: we hold the stock, we run or commission the tests, we pack and ship.

48h median to ship
  • Every order line records the exact batch code shipped — the certificate in your inbox is the certificate for your vial.
  • Tamper-evident secondary packaging, plain outer shipper, tracking on every order.
  • One free reship per order for lost or failed shipments. No argument.
3What we will not do
No human-use claims

Nothing we publish is dosing guidance, a health claim, or medical advice. Our compounds are for laboratory and in-vitro work, and our copy says so everywhere.

No invented numbers

A purity figure on this site traces to a dated instrument run. If we have not measured it, we say we have not measured it.

No silent re-issues

Certificates are never overwritten. A new batch gets a new certificate; the old one stays in the library, dated, forever.
