Good evening I need some help deciding. I am still confused after reading information about steroids. I'll give some bit of information about myself first. I am 21 years old about 5'8 and weigh 115 lbs with about 4% body fat, yes I know pretty skinny. I am in my third month of lifting from which I have gained a little over 3 lbs. I have seen a significant increase in my strength from the first month, more than I thought but any real body builder would probably think different. I take Kre-alkalyn suggested amount only and drink 2 whey protein shakes a day. I also try to eat 2000-3000 calories day. My lifting routine is as follows, 5-6 days a week 1 rest day, I do legs,arms,chest,back,shoulder, and cardio on different days while working other muscles groups as well.

Before I ask, I am well aware of the consequences and do not plan on abusing or using for long time. I only plan on doing this for about 3 months and then stopping.
So if anyone would care to answer few of my questions. What do I buy or should I buy? Any suggestions or links you can give?
