3) 40ml Dermovan or Dermabase + powdered 30mg (6 tablets) Fincar (Indian version of Finasteride) + 2ml 50% alcohol--->(mix into cream).
4) Add spironolactone powder and/or bayberry extract to the formula in either 1, 2 or 3 above. According to Waseda, this version of Fina-spironolactone cream with Bayberry extracts is probably the strongest anti-androgen topical in the world. As spironolactone powder is a little hard to dissolve in oil, increase alcohol and base oil, e.g. 3ml(50% alcohol) and 75ml(base oil). 1800mg (=100mg*18) spironolactone is needed for 30 days use. Bayberry extract must be used separately, for instance, apply the extract and soon spread the cream over it. Note that some spironolactone tablets may not be easy to dissolve, if that is the case, please increase the base oil and add alcohol bit by bit.
