I suppose i would have to get before during and after bloodwork to see for sure. I dnt think it was all mental although i guess it could have been slightly. This 'suppressed phase' as i call it only lasted about a week and a half but during that time sex drive was very low had a few headaches and felt slightly depressed. I have been searching ALOT for a thread ab daa bloodwork they always seem to have the before and during but im lookin for after like two weeks after my main concern is that you may dip down maybe 40% less test for a short time then return to your normal baseline number.
