I've been thinking about trying TRT ever since I heard all the problems it solves, however I am scared of the fertility side effects. I have watched lots of videos on the subject, including yours, and I've seen a lot of people online try TRT. I think the information I have seen is vague; "when you take test your balls turn off, but you can take HCG to turn your balls back on." I fear most TRT advocates and users online aren't backed enough by studies that are convincing to me. I have searched and searched for that china study you mention a lot in your videos and the only study I found was from 2003 which tested 300 men with a low dose of 500ng a month. I don't think that's the one you reference but it's the only one I could find. I haven't really seen any cases of 18 year olds or younger being on it long enough to definitively say if fertility is for sure not an issue long term. I plan to have kids when I'm 30. I don't want to be on TRT for 10 years and then find out I can't have kids. Thats very scary to me. i don't want to cycle on and off TRT to preserve my natural production. And I'd prefer not to take hcg weekly with the TRT (will if I have to i guess). If I could just have a clearer answer I will get on TRT in a heartbeat. I'm pretty healthy and have good habits, I'm active with sports, gym, and did well in high school. I just realized one Day that I have all the symptoms of low test; unmotivated, low energy, brain fog, hard to wake up, anxious all the time, moody. My parents always said that I'm just a teenager I'll grow out of it, it's just a phase. got tested and what do you know I have low test Side note: attached at the bottom is my lab from about a year ago (I was 17) I'm 18 now, though I reckon I feel the same low test symptoms. I'm getting retested soon. I convinced my dad to get on TRT through all the information on your website so thank you.
