Test hits me FAST in the libedo department. Test "kicks" in much faster than the 3-4 weeks that is purported... it is just often that you don't "feel" it kick in for that amount of time. Relatively quickly it can start effecting your blood levels...
It all comes down to you individually... I know with prop, I'm lit up.
Also, trying some Cialis will really help you brother...
