Dont even think about steriods yet, you should gain loads of weight by training and eating right (and then after a lot of self research on steriods can you even think of taking them).Originally Posted by Gmore
You need to eat lots of food (protien rich) about 5-6 times a day (if not more), dont worry about eating clean (low in fats) to much because you obviously have a very fast metabolism and need calories to have surplus requirments for protien to do anything (or it will be used as fuel and just burn off).
Keep a diet sheet and stick to it, I would say eat 3500 calories a day then adjust from there (i.e. if you dont gain add another 250 calories then another until you see a steady increase).
Use only compound movments for a while....long while
You could try this full body workout
Bench press 2*6-10
Seated Shoulder Press 2*6-10
Calf Riase 2*15+
Barbell Curl 1*8-12
Str Leg Deadlift 1*8-12
After take 3 full days rest then repeat, go to failure (on sets stated)and do a few warm ups beforehand.
Use perfect form.
