EVERY BATCH.
EVERY RESULT.
PUBLISHED.
We don't just claim pharmaceutical-grade purity — we prove it. Every single batch is independently tested by accredited third-party laboratories using HPLC analysis and mass spectrometry verification before we ship a single vial.
Your Certificate of Analysis is available on every product page. Download it, cross-reference it against our batch number, verify it yourself. That's what transparency looks like.
// FROM SYNTHESIS TO YOUR DOOR
THE PROCESS
SYNTHESIS
Compounds synthesised in GMP-aligned facilities using pharmaceutical-grade reagents and solid-phase peptide synthesis (SPPS).
HPLC ANALYSIS
High-performance liquid chromatography conducted by independent accredited labs to verify purity percentage and identity.
MASS SPECTROMETRY
Mass spectrometric confirmation validates molecular weight and structural integrity against reference standards.
CERTIFIED & SHIPPED
COA issued, batch number assigned, lyophilised and shipped in discreet packaging with same-day dispatch on orders before 2PM.

WHAT RESEARCHERS
ARE SAYING
from 2,800+ reviews
"Purity verified against our in-house HPLC — came in at 99.81%, matching the COA exactly. Reconstitution was smooth, zero precipitation. This is the standard I expect from a supplier at this level."
Dr. M. Harrison
Verified Purchase
"Ordered on behalf of our lab. The documentation package — COA, mass spec confirmation, HPLC chromatograph — is exactly what our ethics board requires. Delivery was discreet and faster than expected."
T. Owens PhD
Verified Purchase
"Switched from a competitor after their quality slipped. Night and day difference. The batch consistency here is remarkable — same results protocol to protocol, which is critical for reproducible research."
