Okay, sound advice. Thanks. I will wait till I am 25 and I have been trying my hardest to grow. I've been eating a 500 calorie surplus with a 50/20/30 ratio between proteins, fats and carbs, but I am starting to plateau. I am using progressive overload with each new work out as far as weight AND reps go too. I guess my genetics weren't made to pack on that much muscle, but I'll do my best and when I get to 25, i'll start injecting.
