Proscar can prevent hairloss with test because it blocks 5 ARs to which stops test converting to dht. Any one know how successful it is at this or what percentage of hair loss itll prevent. Also it cant be used with deca, but is it safe to use with primo and anavar. Im thinkin of a test E/primo/anavar cycle and im plannin on proscar to reduce potential hairloss to being neglegible coz primo and var are nearly harmless to your hair(am i right on that?) and the proscar will stop test becoming dht.Also is nizoral shampoo good or does anyoe have any other suggestions? So is it safe to use proscar with priom and var, or will it result in the same as usin it with deca?
