Steroid and SARM cycles stop your body from making its own testosterone. When the cycle is over, your hormone levels may drop, which can make you tired, cause low libido, cause muscle loss, and cause other problems. So a therapy can be really helpful.
A proper PCT protocol helps to:
- Kickstart natural testosterone production
- Prevent estrogen-related side effects (like gynecomastia)
- Support hormonal stability
- Maintain muscle gains and strength post-cycle
If you want to keep your gains, the best PCT cycle usually includes SERMs (like Clomid or Nolvadex) and AIs (like Arimidex), but this depends on your cycle.
