You 'should' notice it soon. 50 mg's used during post cycle may or may not be enough conisidering you are already semi-shut down. If you don't notice anything by day ~14~ , I'd suggest you up your dose to 75 mg's. Some people take 100 mgs/day but I think this appraoches overkill.......howevder,considering everyone responds to different doses of hormones (drugs in general) it is "fine".
