Lab Results
Every batch.
Proven on paper.
We don't ask you to take purity on faith. Every product we carry is backed by a Certificate of Analysis from an independent, third-party laboratory — tied to the specific batch in your vial.
How We Test
From production run to your research bench.
Synthesis & Weighing
Each production run is synthesized and precision-weighed in a cGMP-compliant facility before it ever reaches a lab bench.
Independent HPLC Analysis
A third-party laboratory — never in-house — runs high-performance liquid chromatography to quantify purity down to the compound.
Certificate Issued & Shipped
The lab issues a batch-specific Certificate of Analysis, which ships with the product — not on request, not after the fact.

Independently Verified
≥99% Purity · HPLC Verified · cGMP Facilities
Every production run passes through an independent third-party laboratory before release — HPLC purity analysis, sterility testing, and bacterial endotoxin screening on every batch, not a sample set. Manufacturing is carried out in cGMP-compliant facilities from lot to lot.
