He's doing Deca or Tren or something else that makes his hard-on's less hard and full, so he's smaller. He should put some Hot Stuff on there before sex - that'll do the trick... LOL
Could be that she doesn't like him juicing and is screwing with his ego.
Other (terrible) scenario is that she's cheating on him with some guy who's hung like a brontosaurus and wants to have an excuse as to why she doesn't feel the same to him.
Or, maybe his dick IS shrinking! I talked to a guy who knew a guy who trained with a guy who was a lot bigger than me and he was juicing for like 3 months straight and his dick shrivelled up, got all black and he had to stop b/c he thought it was going to fall off... But that's just what I heard.
its gets bigger when your on ... your producing high amounts of test .. you get bigger when your on also becasuse you have access skin due to shrinkage in testicle area.. i actually no bullshit grew .250 .inch
I'm with Mr.Huge.... that'll save him the trouble of buying a dip belt, but I don't know if people are gonna wanna use those plates when he's done. lol.
Seriously though... total bullshit. DHT is the hormone responsible for penile development during puberty (higher test levels = more conversion to DHT which triggers penile development). Combine that with the fact that test levels hold a positive correlation with GH levels... Like Ivan and the boys said, if anything, you're gonna grow.
