I am a 23 yr old male 6'/151 lbs. and I have been considering starting a cycle but I am unsure of what to use. I workout 1 1/2- 2 hours everyday and I have been using C4 pre workout and protien shakes afterwards. I also eat plenty of high protein/low fat foods but I can't seem to put on anymore mass or strength. I have always been described as "lanky" and I want to get bigger. Anyone have any suggestions of what, if anything, I should do?
