What has proven much more effective is running nolvadex concurrently with clomid and HCG. HMG is used to improve sperm production and is not as effective at PCT as HCG because it is FSH dominant. Caber wont do much at all for PCT. Ostarine used to be the rage when it came out but I have seen no documented research showing any significant muscle gains...Ive also run it a few times with no results.
