First off I wanna say I do side with the longer the cycle probably the longer the recovery just hoping someone had prove.
As far as everyone running 30 week cycles are not popular because of the health side effects. Running even high levels of test alone isn't great for you for that long not to mention what tren would do to you. And your body kinda figures out what's going on after awhile and gains drastically slow after 8 weeks or so. Anabolic hormones are Hgh but your body has raised your catabolic hormones also.
So in no way do I think people should do 6 month cycles but just wanted to see if theres any prove of shutdown of 8 weeks vs 52 or what have you
