Yes, it is in the safe zone. 50-75mg a day (I take 25mg of a specific pharma grade proviron) is enough for proviron and it will work well with the test, it will synergize with it and amplify its effects as well as give you a high libido, keep you somewhat dry, keep testicles stimulated (you'll still need pct!).
Help abit with gyno (better AI's exist like adex and aromasin) I doubt you'll get gyno at your dose but who knows some people are more sensitive to it than others, so keep adex or aromasin on hand.
