normally the suggestion is to wait 2 weeks after your last injection to start PCT…
but that doesn’t mean the test is completely out of your system. the half-life of test e/cyp is around 5 days, so if you injected 250 mg on your last injection, it would be 125, 62.5, etc… as would the previous injections, as well.
if you really wanna fingure out the half-life time table, then i’d suggest using an Excel spreadsheet… otherwise, i’d just wait 2 weeks after your last injection of test e/cyp (and 3 weeks if it’s sustanon).
