I assume you are talking about the "legal steroids" or whatever the hell they are. They don't work, it's just a BS marketing ploy. The only reason they can call them steroids is because they are made from the steroid skeleton (4 linked rings, 3 six membered one five membered, yada yada) and I don't even know if THAT's true.
Maybe they don't even have the skeleton and they are faking the whole thing. There is a difference between just steroids and anabolic androgenic steroids (AAS, and none are legal unless prescribed). Cholesterol is a steroid, but it is not an anabolic androgenic steroid. The only ones that are are the known synthetic derivatives of testosterone.
I suggest you do a bit more research into what you want to put into your body, do some searches. And for the love of God learn to spell steroids.
