T effects after restarting

I'm about a month on subq Testosterone shots after being off of it for ~3 years. The last time I was on testosterone, I took it for almost 2 years and had some decent changes.

Now that I'm restarting, I feel like I'm seeing a lot of the changes I did in the beginning the first time, but A LOT faster. Like my voice started cracking after my 2nd shot.

I just want to know if anyone else has stopped and then restarted HRT after some time and also experienced this? Or if you've restarted Testosterone, what did you see first and how did it differ from the first time you took it?
