Reliability at institutional scale.
We're one of the only companies actually synthesizing peptides on US soil — not repackaging imported powder. Every compound is built from the ground up in a US cGMP lab, verified by HPLC and mass spectrometry, and screened for endotoxins through an ISO/IEC 17025:2017 accredited laboratory.
We probably already supply your favorite brand.
Many of the peptide brands you already know and trust source their material from the same US facility we do — they just put their own label on it. Skip the middleman markup and buy direct from the lab that actually makes it.
Two ways to stock your shelves
Choose your format
Every compound we make comes two ways. Stock classic lyophilized powder, our premium pre-reconstituted Black Label, or both — all from the same American lab.
Made in USALyophilized Powder
The research standard. Freeze-dried, tamper-evident vials synthesized from the ground up in our US cGMP facility — the same material trusted by labs, clinics and the brands you already buy.
- Synthesized in our US cGMP / ISO-compliant facility
- ≥99% purity verified by HPLC + mass spec
- Third-party COA + LAL endotoxin testing per batch

Black LabelPre-Reconstituted
Our premium tier. A proprietary inclusion complex delivers peptides already in solution — room-temperature stable, no cold chain, no mixing. No other supplier offers it. Open the vial and administer.

Identity and purity confirmed by HPLC and mass spectrometry. We hold a ≥99% purity standard, batch after batch, and publish the data to prove it.
Sterility & Endotoxin Testing
Every batch is screened for bacterial endotoxins by LAL testing and ships lyophilized in tamper-evident vials — the standard most suppliers skip.
