Ok... All my medicine of Bromocriptine for Parkinson's disease says "Bromocriptine Mesylate Tablets contain bromocriptine mesylate (C32H40BrN5O5·CH4SO3) equivalent to 2.5mg Bromocriptine." I was told CAS numbers as well.

Looking at the formula the molecular weight is 750, 654 of which is bromocriptine and 96 is the mesylate, so your BM powder is 87.2% by mass bromocriptine. To get 25 mg of bromicriptine you therefore need 28.67 mg of BM powder.
Edit: damn just realised the thread is a year old! Will be more careful not to necro dead threads in future!
