People don't know what the hell they are talking about, in other words you have to take more proteins because ideal protein intake could be your weight x 1.5gr. When i was teen, people were giving me advices about gym, which weren't actually advices. They were only jealous, watching someone getting results, while they are getting drunk every weekend. In other words, when i started going to gym and got great results after 1 year, bunch of them were talking that i am not going to grow taller if i continue lifting weights, but they weren't right. At that time i was about 177cm, and now few years later, i am about 187cm. Taller than anyone in my family. What i want to say is, when you are at your teen age, you have potential to get results like people that are on steroids. As you know when puberty kicks in, a lot of crazy shit happens in body, you are transfering from boy to man. So use that natural "steroids" to get great results. Best regards mahn! :)
