Why us
We don’t guess. We document.
Most wholesale peptide vendors hand you a SKU and a price. We hand you a qualified vendor chain, an independent batch test, and a per-lot certificate of analysis on request — so you know exactly what’s in the vial.
01 · Source
Sourced in the USA.
Compounds are sourced through a controlled US supply chain with documented vendor qualification. Domestic distribution means no customs holds, no opaque chain of custody, and no surprises at the door.
02 · Verify
Third-party HPLC/MS on every lot.
Each production run is independently tested by a contract analytical lab. Identity, purity, and quantitation are documented per lot — not per product line.
03 · Document
Lot-tracked COAs, on request.
Every batch is third-party tested. The per-lot certificate of analysis is available as a paid add-on with your order — searchable on /coa once released so your customers can verify the same lot independently.

Our process
From column to crate, in three documented steps.
The journey you followed above, as the checklist we run on every single lot — no exceptions, no untested releases.
Source
Sourced through a controlled US supply chain
Compounds are sourced through qualified vendors and routed through a domestic US distribution operation. Every inbound lot is logged, segregated, and held until release — no opaque overseas chain of custody.
Verification
Independent HPLC/MS analysis on every lot
Each production run is shipped to a contract analytical laboratory for HPLC coupled with mass spectrometry. Identity, purity, and quantitation are documented per lot.
Release
Lot-tracked, with the COA available on request
When the COA returns the lot is released and the lot number is searchable on our COA page. The per-lot PDF is available as a paid add-on with your order, so your customers can verify the same lot independently when they need to.
