In my mind at 6-2 175 you could look more muscular than Bradd Pitt in Fight Club or you could look plain and unfit. You have youth and extraordinary height, which tells me that you likely want to add quality muscle and definition. Recent pics tell the true story, but if you simply want to add more muscle and definition than steroids are only going to help you, in my opinion.
This is where I again emphasize informed, moderate, commonsensical steroid use. Study up on steroids. Read those who endorse and those oppose. I encourage you to Google "HBO Real Sports Steroids." Read Jose Canseco's tell-all book, "Juiced."
How hard have you trained and what have you eaten and drank the past 6 weeks?
