My boyfriend had his first shot of T about 4-5 days ago, but his voice is already starting to slightly change and break a lot. I don't know if this is because he naturally has a lot of testosterone in his system already so it's speeding up the process, or if it's just normal, or what. I've seen videos on youtube of people who have slight changes after a week, but its only after the first month or two you actually can noticeably hear a difference. There isn't a big difference in his voice, but it's happening so quickly, I was just wondering if it's normal?

i noticed my voice breaking the day after my shot but my voice evened back out a couple days after.....

My voice started to change at around day 5. and it definitely was cracking day 11. I noticed if I took Teen Advantage 1-a-day health, my results showed more, I guess. That's great though
I recorded my voice on day 5 and there was a change.
