Optimize-T &/or M-Test are both great natural testosterone boosters.
Whether you need something for estrogen control support depends on what you were running and doing PCT from.
If you need something to help with estrogen control support, Inhibit-E is a great option.
If you need something to help with prolactin control support, Inhibit-P is a great option.
We will also have a great option coming under CEL within the next couple of weeks named Cloma-Plex. I can't go into any details yet, but its a very exciting and comprehensive ingredient profile. It isn't meant to take the place of M-Test or Optimize-T, but will be great additions to them whether one's goal is PCT or a natural testosterone boosting regimen.
