Damn dude. I'll try not to go off on you, but it's not about being young or immature or what ever, it's about causing permanent damage to their system. Until the glue has dried on their HPTA, shutting it down and fucking it up with steroids can cause irreparable damage that will fuck a brother up for life. No your nuts don't turn black and fall off and blood doesn't come out of your eyes, and you will feel fine, even after your cycle, but your natural test production can be permanently effected. Often times you won't have any idea until you do get a little older and things really slow down. It's like banging a chick with herpes and not waiting to put on a condom. It sounded like fun at the moment, but now you have to deal with it for the rest of your life, which can be a really long time. Guys need to slow down, relax and enjoy the ride. You will get there. Just wait until your body is ready. I promise you when you're 40 years old and on your way to the testosterone replacement therapy (TRT) clinic, again, you will not be thinking damn! I'm so glad I put on 10 pounds of muscle when I was 20, if I had waited a couple more years, that would have been so lame!
