So you're 19, balooned up after stopping working out during high school, you've been taking t-boosters for a while, and you're still asking about steroids?
Get a fuckin clue. You're 19, unless you have low T, you're gonna fuck up your endocrine system, if you havent already. I'm not educated about steroids, but I sure as hell know not to take them until you've had a serious diet, and workout plan for years. You, are not this case.
Stop worrying about drugs to take when you can get your ass back in shape with a solid nutrition plan and workout plan.
