Proviron is a very good drug for hardening on solidifying qualitative gains. Very popular.
Begin taking the Proviron a week before your cycle at 25mg/day and continue throughout your cycle at the schedule of 50mg/500 mg of Test. This is done because Proviron has an affinity for plasma binding proteins(SHBG), therefore enhances the effect by displacing a higher percentage of receptors into a free, unbound state.
