You DO NOT need caber for gyno. That is not good advice. You need an aromatase inhibitor such as letrozole or arimadex to control estrogen while on cycle and for preventing/destroying gyno you need to use either nolvadex or raloxophene. Ralox is my preference because it seems to be greatly more effective with far less side effects than nolvadex. You don't use caber or an AI to reduce gyno, that's just ridiculous. Letrozole can sometimes be effective to shrink gyno but that's not its purpose and it isn't even close to being as effective as nolvadex or raloxophene. Caber is a dopamine agonist which is commonly used to reduce prolactin, and it will not have much of if any effect on gyno reduction..
