10%? blond dude is half that, other dude close to it but holds more water, i dont have the expertise to say this but... i suspect blond dude is not on diuretic, maybe small dosing tren/mast/test prop... other guy is prolly on a pill or just test e. also I wouldnt discount hgh for blonde guy, that may be the only difference. reason I don't think they are on diuretics is that it gives a grainy dry look to the skin
