Im making a small batch of Estradiol Valerate for my wife. I’m a little confused on the proper portions. I have everything that is needed (I believe). I have a proper receipt from a pharmacist; as follows 40 mg/ml EV powder 4gr BB. 44.7gr BA. 2 gr Castor oil. as 100ml I want to chang the strength to 20 mg/ml and a quantity of 50 ml. My confusion lies here; if I just reduce everything to half then the strength stays the same. If I just reduce the estrodial I’ll still get 100ml if product per receipe. I’ve thinked myself into confusion.
