A few notes on this compound.
Lyophilized means freeze-dried: the compound is supplied as a dry powder in a sealed sterile glass vial. Reconstitution protocols are a matter for the qualified researcher and the applicable laboratory procedure; Reviva does not supply reconstitution or dosing guidance.
Lyophilized vials are stored at 2–8°C, or −20°C for long-term storage. Storage conditions after reconstitution are a matter for the applicable laboratory procedure.
The certificate of analysis matched to the specific lot dispatched — never a generic — covering identity, purity, sterility, and endotoxin. It is emailed at dispatch and available to every member in full.
Because every vial is dispatched cold-chain and lot-matched to its certificate of analysis, we are not able to accept returns once a parcel has left the dispatch room. If anything arrives other than as described, write to care@livereviva.com.
