FEKE-RB36

I've been lifting weights for about 5 years in total. 3 of those years to this day i train religiously eating clean and what not. Im wanting to start my first cycle and was wondering what you guys recomend. I want to bulk but still retain my speed. The only knowledge i have on steroids is from forums like this so it would be great if i could get some help.

Im 6 feet 245lbs, 10% body fat.

thanks
