It is tempting to increase testosterone through illegal drug use, yet the obvious downside (health implications) outweigh the temporary benefits. In lieu of using such drugs, one may increase natural testosterone levels through proper diet and exercise techniques while avoiding any of the associated side effects (due to the body's close regulation of naturally produced hormones, testosterone cannot rise to dangerously high levels, and will instead increase to a safe maximum). Thus, why not use the natural approach? Enjoy a testosterone boost WITHOUT health risks, and all that's necessary is proper training and diet principles -- this is how all natural bodybuilder's achieve muscle gains / fat reduction.
To clarify one important point -- it is IMPOSSIBLE to develop freaky, inhuman professional bodybuilder size without using MANY illegal drugs (steroids, growth hormone, insulin, etc), but you CAN produce a smaller version of a steroid monster through very specific diet and exercise techniques -- I have accomplished such results, and am safely enjoying very high levels of muscle while maintaining a low body fat percentage.
Remember, PROPER training / diet leads to dramatic, yet safe, increases in
muscle mass -- I have achieved tremendous success (over 60 pounds of muscle) without drugs, and will show you how to improve your body through proper diet and exercise techniques.
