If you are going to take something, take the real thing. Ill tell you why:
1.) The FDA doesnt regulate supplements, well they didnt use to. That means all the supps that were out before a bill was passed was grandfathered in. Many supps dont even contain what they say. Some creatine products were proved by lab tests to be nothing more than sugar.
2.) The prohormones have almost all of the same sides as real AAS. Meaning they still can cause gyno, they are still metabolized in the liver, ETC...
3.) The cost of prohormones can actually be more than the real thing.
4.) The results of prohormones are almost non-existent, nothing compared to real AAS.
as far as your question about breaking out.... my skin was VERY clear during my cycle, it wasnt until i hit clomid that I started breaking out on my back and shoulders.
