Nature is the greatest power that we know of - more so compared to atomic bombs simply because atomic bombs are basically one part of nature at the office. And generally speaking I do not find the human that intelligent because of the continual striving to out-smart or manipulate nature. Surely it's much more effective to seek to understand the natural world in order to work with it, instead of to get egos all bent out of shape with attempting to rule it. With regard to testosterone levels as well as their importance to a healthy lifestyle, doctors, sports people and body-builders have often sought to take short cuts by using prescriptions to get done what dynamics will happily assist us with - namely performance enhancement, improved muscle mass, reduced body fat and an overall all-round vitality for living such as the impact of its on the sexual expression of ours. We wish to be more manly, therefore we would like more supplement boost testosterone (best site) - it is as easy as that actually.  
The issue is that drugs are never and not will be the solution to our prayer for greater prowess as men. The real answer as always lays within us. All we need to do is to get the brain of ours to detect we need far more testosterone and it will gladly get on to the responsibility of causing a lot more testosterone to be grown. Quite simple, the body knows that when the muscles of ours are burning up from surplus pressure which they have more testosterone, and so the mind demands the pituitary gland to buy "the ball rolling" as it had been, and to trigger the testes into far more testosterone production. That is, if we do a couple of minutes each day of muscle burning workout, then the mental faculties and body will naturally give you the increased testosterone that we want and that increase will quickly flow through our everyday lifestyle into a greater number of metabolism, activity and muscle-mass building while quickly losing the body fat of ours.
