Personally, I think you're either for or against steroids regardless of whatever factors. I mean, Mike Tyson took steroids since he was a kid - probably way before he was 18. Something is loose in his head but physically he's like any other person, only more muscular. I don't agree with steroids in ANY case. The only exception for me might be if one would take steroids for a short period of time that would enable this person to make a huge monetary profit, which would (for lack of a better expression) make them set for life. That's short-term and the effect would be MINIMAL.
Now, having said that, I don't see why anyone would take steroids in any other scenario but the one described above. If you're 175 and trying to hit 190 by the summer...I'm sorry to say it, but you're mentally challenged. You will NOT gain 15lbs of lean muscle in 2-3 months naturally. All you can do is work on getting cuts. For you to go from 175 to 190 while cutting fat is going to take a lot longer than you think. You'll probably lose 5-10lbs of fat, so, in fact, you have to put on even more muscle to go up to 190. You're not putting on 15lbs of muscle, you're putting on 20-25lbs of muscle since you're losing fat. IF, and that's a big IF, you stick to your diet and training plan, you'll be lucky if you can achieve that in 2 years. Good luck. |

Shit, if you were bulking I'd say go for it. I'd evaluate your diet to make sure it matches your goals. At 18 I was over 200lbs, solid, abs,... and absolutely 100% natural. You DO NOT need gear to reach your goal of 190lbs. Get a good workout routine and diet and being ripped at 190 should be very.. very achievable. Of course you seem to ignore everyone's advice here, so you know what? Do what ever the fuck you want, and when that doesn't work....reread this post and ask for some help on your diet and routine. Good luck bro.... you need it.
