Sir I would have to disagree. This individual needs food as Capebuffalo suggested. IF he would do a cycle 500mg Testosterone alone should suffice! Diet > Gear

I like dbol and his results would start coming a lot sooner and provide a nice anabolic transposition after 4 weeks. Note to OP. You have to continue to eat and train like you did on cycle! If you say you can gain fat but not muscle that means you aren't eating enough protein and/or working out like you should. OR which is unlikely you have a long CAG repeat or MAIS
