I don't know about the MSM cream. Sulphur and spironolactone. are two chemicals I don't mix. I get the "feeling" they would react together and get "stinky". But I really don't know because I've never put MSM in spironolactone. cream.
The other two creams look great IMHO.
You've found your homemade concoction cream Kento!! :bravo:
