Supplements that try to immitate steroids are more expensive and are dangerous.
Consider that decades of research has been done on the effects of steroids and how they act in the body.
Every day new supplements are hitting the market that have had minimal research done if any. Many of which make claims that have never been evaluated by the FDA.
You have not done enough research or you would realize that there are injectable anabolic steroids that when taken in a logical and structured manner, not only promote muscle growth, but good health as well. There are plenty of compounds that yield little to no side effects.
The same can not be said however of copy-cat compounds. What can undoubtedly be said is that there is some greedy executive eagerly pushing this product into stores and making inflated claims about its' effectiveness. These claims are being made with little to no research or empirical evidence to support them
It sounds to me like you are looking for a quick fix my friend,which too, is a recipe for disaster. I suggest you do quite a bit of research on real steroid compounds, while maintaining a strong focus on your training regimen, and then begin to gather ideas about what may truly interest you in terms of steroids. Hang around and ask questions. We will help you any way we can. Good luck.
