These are completely things. Liver protection is liver protection, it is that simple. However, PCT is post cycle therapy. This is a therapy you got to carry out after each cycle. It has three major purposes:
1. Keep the gains made on cycle and avoid fat accumulation
2. Prevent an estrogen rebound after the cycle.
3. Help recover the natural testosterone production, as all steroids without exclusions will cause suppression of the natural test production.
Therefore, it is absolutely necessary to use such compounds as clomid, nolvadex, and Ostarine MK-2866 with some natty test booster for PCT.
