Fuck I wish I'd looked like that before I'd ever worked out. Was a skinny ass bitch, skinnier than this guy's before pic.
Keep going man bro, though I don't get how you are 215 in that pic, must have some chunkachunk going on in the legs (good or bad). My advice in training is aim for what I would think are the big 3. Deadlifts, squats, and bench. Do them well and go at them hard (get someone with experience to show you).
Although a member mentioned that he ate >10,000 calories per day, I would suggest that aiming for 3000-3500 calories is probably fair, up to about 5000. Can I ask how you found this forum? Try not to get too excited about steroids as well, don't even think about them for another 5 years at least (my opinion only)
Good luck.
