About

How we source, test, and verify.

Testing
Every lot is tested by named independent labs (Janoshik Analytical, Colmaric Analyticals). We do not self-certify.
Standard
HPLC for purity, mass spectrometry for identity, and endotoxin (LAL) testing where applicable, reported per lot.
Fulfillment
USA-based fulfillment with same-day dispatch before the daily cutoff and cold-pack shipping.
Provenance
Sourcing and process specifics are published only when accurate and current, placeholder until verified, never false precision.
