Don't know about forever, but let me tell you that after close to 2 years off the juice, several anti-estrogen therapies and several HCG cycles my testicles have NEVER returned to their former size and neither has my sex drive. But strangely enough they do return to normal size while on sust. Don't ask why.
Anyway, some days they will return to their former glory and be large and full, and will stay that way for up to a week then all of the sudden they will shrink and my sex drive will go down, my face turn more puffy and i will start to gain fat. Then out of the blue it will all reverse, so yeah there is a chance rids will fuck you up in some way. I personally have to go the doctor and get some blood work done because this is getting extremly frustrating and has taken a toll on my relationship.
Sincerely
GWL9DTA4.
