It matters to determine when you should start .
Last 8 weeks with test, which ester? if it´s a long ester lke cyp or enanth, wait 3 weeks after end of injections to start.Classic would be 300mg 1st day followed by 100mg for 10 days and 50mg for more 10 days, but I sincerily doubt that Clomid will handle your recovery by itself or in 21days, maybe you´ll need to take it longer, maybe some HCG will be required, and some supplements to keep libido high, or even Proviron .Blood work to follow up is mandatory , IMHO, specially in your case with such a long cycle with such inhibitory drugs on it.I know the answer is kind of generic, but there is NOT such a thing as the RIGHT post-cycle therapy. Not yet, anyway.
