I'm going to start a 12 week Test E/Dbol Cycle.

1-12 Test E 500mg/week
1-4 Dbol/ED

im sitting around 15% BF

should I use GW501516 to drop down to 10% BF before I start the cycle??

also, i've read that GW501516 changes Fast Twitch Muscle Fibers to Slow Twitch, how would this affect me??, I have a contest mid July! would this conversion change the way I look? i have no idea

any help would be appreciated!!
