Training hard , eating the right food and amount , have perfect rest and using alot of high quality gear like Med Tech you can be a great amateur or even turn pro without genetics , only with hard work and pushing dosages high. But to be a good competitive pro you need to born with amazing bone structure genetics, also good genetics on building muscle and burning fat using less gear , great muscle bellies ( high dosages hgh + slin can do that to ), and even with all the genetics have to work super hard and do all perfect . Genetics is not just building muscle is also bone structure , how you handle sides , muscle shape . So to be a top pro you need alot !

And a huger sponsorship amd alot of money .
