Very true... Both work, stay on for 4 weeks, Nolva, Clomid for PCT and you'll be fine... Remember to take liver protection (Both are toxic...SD being worse on Cholesteral as well) and gains will be just under 15lbs in 4 weeks. Up cals, if you use SD you'll have to really increase your Carbs, as it really works well when you do... This is all info i got from searching bro, as i am interested in both...
Also look up Phera-Plex, i say you'd have better luck with that.
