Following a compound creates a clean baseline from the updates currently known. When BACToBasics later records a new research source or material development change, the My Tools update badge can surface it as new for you.
BACToBasics provides educational research organization only. A development milestone does not predict future approval, and a research record does not establish that a compound is safe, effective, approved, or appropriate for use.
