I used to left relatively hardcore for about 15 months straight. I gained about 40 pounds over that time, but i started a lil guy. Like 140 at nearly 6 foot. Anyways, i went to school, and got sick a couple times and did a poor job of hitting the gym. I really wanna get back into it now cuz i'm pissed with myself for letting all my hard work slide. I'm about 170 now at 6 foot, 20 years old. I'm contemplating spliting an "Ultimate Stack 2" from SDI Labs with a buddy of mine. The stack consists of Winni-V, D-Bol, and a Juice Pack training system. Since i'd be splitting it i'd only be on it for 4 weeks instead of 8. I really only want to do this to let me start seeing results that i can feel good about, then i think i will go all natural once i have a base. Does this make sense? Is SDI stuff any good? Are there any huge risks for someone my size / age / experience? Appreciate it.
