Im gonna jump in for a sec,i TOTALLY agree with Cobra and others who are telling you to wait man,you are too young,let me tell you from personal experience!!!!im 44,and on lifetime TRT,not fun!!!!,and yea i use as well,but i done my research,ask questions,done more research and ask more questions,and still do it everyday,man you are just fucking yourself up on down the line when you get in your 30's or 40's,trust me man,im not bashing or flamming you,im just telling you straight up,you WILL regret this when you are my age,trust me...TRT for life is not fun,plus what other damage you will do to your endocrine system as well,i didnt do my first cycle until i was 39,i still learn something everyday.....anyway man,good luck with your cycle,hope all goes well
