Thanks for the post buddy, i done some research myself and found this;

Basically from what I read.. I gathered that if you abstain from ejaculation for 7 days on the 7th day your levels of testosternome will increase by 50%. So sex and jacking off is ok as long as you dont cum.
So mysterys rule is actually a good idea according to this article, but as with everything I read on the internet Im going to try it for myself.
I haven't masurbated or had sex since sunday and Monday is one of my Gym days so im going to see how well I perform next week. If it works im going to switch it to my sarging night (Thursday) so that I have extra levels when im out sarging.
I also found this link which might be useful for guys wanting to really amp up their levels.

I'm already going to the gym, eating right and avoiding alcohol so I guess all I can do is cut down on the sex and eat more garlic.
Will post back to let you know how my gym session is on Monday

(unless I end up fucking on thursday night then its back to square one lol)
