I wouldn't do it that way, just get some clomid and nolva and do it the right way. When you do it that way you would for sure need a doctors help so he can tell you your test levels and adjust your dosage according to that and your weight. 100mg of test will shut you down so if you "lowered your dose regularlly" you would still hit a hormone crash. Just keep your dose at 500mg a week and then start PCT 100/50/50/50 clomid ED and 40/40/20/20 nolv ED and you will be great.
