Depends on the cycle bro... what types of A-A-S you've used... H-C-G is often used for most average cycles, typically best run at the end of the cycle or even throughout in smaller dosages. For P-C-T proper, clomid, nolvadex, Sustain are all options (there's lots of debate on this going on right now). Typical P-C-T will last 4-6 weeks, again, depending on your cycle. Bloodwork is always a good idea to confirm you're recovered.
