if youre jabbing testosterone, right into your pee-hole, in a few weeks your balls shrink.

why? cause yer bod is like "BRAH... IM JACKED. no need to make testosterone."

same for most things.

take melatonin pills... now yer fatty-meat-burger, sitn on the crown of yer noggin, stops juice'n certain juices.

the only diff is if you stop jab'n yer PEEN, your balls grow back. yer brain starts juice'n whatever to compensate for whatever it needs.
