Sorry matt but NOT pro genetics.....
Are you saying this based on his structure? Because the only way I am evaluating it is depending on how much gear he is currently taking, if any.
If he is using little to know gear, at 20, I would say he has the potential to grow. If he only started training within the past two years or something, and has not done a cycle yet, I wouldn't bet against him growing like his dad.
If he's already mega-dosing, then I would say he does not have pro potential.
