Wait until ya get older, you'll be welcoming some shrinkage so as not to sit on the damn fun bag LOL. I never had a long saggy sack in the first place, but they have shriveled a bit but it's not as bad as one might think. Only weird side effect is loss of quantity as far as a big build up load that used to make the ole lady look like she dunked her head in a bowel of glazed doughnut icing

(far from that actually but sounded good)...but seriously, your nut quantity will go down as well, and I've noticed it's thicker than it used to be before starting TRT. Actually doc emailed me the other day about rescheduling apt or just putting it off another 6 months if he got a lab from me up here (2 hr drive to see him) but if everything is within reason, he said we can just forgo nexdt weeks appointment. I did give a fairly detailed log of how things have been going and mentioned the lesser quanitiy of load and he said it's just one of the side effects of being on T since with the synthetic stuff, the pituitary gland sees that everything is hunky dory so it doesn't produce anymore, and as a side effect...da balls get smaller and no more gallons of baby gravey
As for sleep, I've been a horribly light sleeper my whole life, and the second my eye's open, even after just an hour of sleep...Im awake until I crash again later. I'm actually the opposite, I'm getting better sleep now, BUT I've noticed my anxiety levels have risen a bit, so going to be paying more attention to correlate if I get higher anxiety shortly after my shots or just before my shots.
