yeah man, don't mess with your body right now or you'll for sure regret it come years down the road. your test levels are already extremely high right now so take advantage of that. Trust me i'm a serious ectomorph, i put on weight with extreme difficulty, i started working out at 18 and within one year, I put on some serious muscle weight. Just get your diet in check and hit the weights hard. if you choose to use AAS in the future, wait for your time. That time is not now though! good luck!
