its O-K bro. not worth the money at all in my opinion. better off going to the meso rx site that in my opinion has better profiles and lots more valuable info. i would rather buy chemical muscle enhancement or nelson montana's bottomline bodybuilding which are both much cheaper and probably have more valuable info in them. steroids 101 is very cut and dry and doesnt offer anything special. THAT is its major flaw. the pictures are cool, but not that helpful. there is only one picture of primo in there and it is of the box only! what kind of stupid shit is that? meanwhile, theres like 10 pictures of clomid and other bullshit that rarely gets faked. to be honest, i regret spending 60 bucks on it. would rather pay 80 for the other 2 books i mentioned which i heard are good but dont know. maybe someone else knows?
