About us

A research-only supplier built on transparency

We supply high-purity research compounds and peptides to qualified researchers — built around three things competitors treat as optional: speed, transparency, and independent third-party verification. We are not a pharmacy, not a compounding facility, and we do not sell health products.

US GMP-compliant

Every compound is synthesized in a GMP-compliant facility based in Texas under documented protocols.

Independently verified

We third-party test every product in an ISO/IEC-accredited laboratory for purity, content, endotoxins and heavy metals.

US-based & US-shipped

Headquartered in the US with US-based support by chat, phone, and email. Orders before 3PM EST ship same day.

Most-reviewed for a reason

Thousands of verified reviews from researchers who cross-check our published Certificates of Analysis.

Our standard

We believe a research supplier should be judged on what it can prove, not what it claims. That's why every batch ships with a Certificate of Analysis you can match to your vial's batch number — and why we publish our testing methodology openly. If a batch doesn't meet ≥99% purity, it doesn't ship.
