PCT, or post-cycle therapy, is a protocol you follow after completing a cycle of SARMs (Selective Androgen Receptor Modulators) or BCAAs (Branched-Chain Amino Acids).
SARMs and BCAA supplements increase muscle mass but also decrease testosterone levels, especially in men. Taking SARMs provides a high dose of testosterone, and your body experiences a sudden drop in the hormone when your cycle is over.
It may take months to years for your body to naturally restart testosterone production. Meanwhile, you might feel low energy, libido, and depression due to low testosterone.
You can speed up this process by boosting testosterone production through post cycle therapy.
