Coming down from higher dosages of test will set the body up to crash and make recovery harder, especially if you have to wait a few weeks for a long ester like cyp or enanthate before starting PCT.

Tapering down is an option, but not as effective as replacing a longer ester with a short ester like Propionate, or no-ester like suspension in order to begin PCT sooner.

With the shorter half-lives there is minimal waiting, which I always try to avoid.
