I ran a cycle of superdrol 6weeks after a previous cycle of the stuff, i'd say it was about 70% as effective as the first cycle with probably slightly worse sides.
This year i ran two cycles of epistane about 6 weeks apart, the second cycle was about 80-90% as effective in strength gains as the first cycle, with both cycles having zero noticeable sides (I actually only noticed positive side effects like increase libido during and post cycle, and it totally rid me of gyno)
Im planning for my third cycle of epi (havoc this time) but planning to stack it with max lmg.
