chemist told me its not good to mix proviroln while on a cycle it has very strong effect on the androgen recepter and does nt let the olther anabolloics your using not work as you would want.hes a well known chemist trainer.
also masteron sholuld not give any problems unloess yolu mixx other androgens like cyp,anadrol.leave the proviron for after cycle and use with hcg if i were you i wolulod fing another drug to mix with mast. just thought this might help u. olh arimidex to me is very good drug. i woluld always choose it compare too others.
I agree on using adex. Do not use proviron during PCT, as it is counter productive. Proviron is a steroid, and it will not help with recovery. There is a solid bro on OLM who just recently ran this experiment with blood work, and his blood work came back fucked. HCG is also suppressive and should be run during cycle, and not during PCT.
