How It's Made
From synthesis to your bench
Every Renova lot follows the same path — synthesized in the USA, independently verified, and dispatched same-day with its COA.
Step 1Synthesized & sealed
Solid-phase synthesis in U.S. cGMP facilities, then lyophilized and sealed under controlled cleanroom conditions — built for ≥99% purity and shelf stability.
Step 2Independently verified
Every lot is HPLC- and mass-spec–tested by an accredited U.S. lab, and its Certificate of Analysis is published and searchable by batch number.
Step 3Same-day dispatch
Orders placed before the daily cutoff ship the same day — discreet, tracked, temperature-aware packaging, shipped across the USA.
