I wouldn't pulse it. Just do a straight cycle. if your worried about libido get proviron or add some test in there. Dermacrine will help also if you don't want to add test. The first and only time i ever pulsed i got gyno from it i noticed it right away and got rid of it in a couple days with letro. I didn't have a flare up until a month after i was done and used tormefiene as my pct. I'm not prone to gyno so i stay away from pulsing and do long low dosed cycles with only 250mg of test. i keep all my gains and i use HCG to keep my natty test levels going. if i were you i would run the sd for 3 weeks and the dermacrine for 4 weeks then do a 4 week pct of clomid 50, 50, 25, 25.
