In the slimmest hope that you are a genuine member, and not just a spammer who cobbled this idiocy together to pimp the website I just deleted from your post; I will tell you that most fight organisations do blood and pi$$ testing for competitors, so turning up full of stimulants and test. will just get you banned from competition.
Outside of that, there are health risks, and also the fact that it is highly doubtfull that you cannot improve just by getting a better trainer who knows what they are on about, instead of a guy who has rn out of ideas and wants to pump you full of chemicals instead of training you properly.
