I've been working out with my little brother lately, he's 16, 155 lbs, he's had incredible gains lately and is doing quite well, him and i have been wondering how safe it would be to put him on a NATURAL Testosterone Booster, like TRIBEX(tribulus), or 6-oxo.. maybe even the new instone Testosterone booster. I dont see the harm since its simply your own testosterone just increased to a higher level, but i want your guys's opinions.. thanks
