I like it because it lower prolactin/progesteron levels as well as estrogen so it's ideal for deca and tren cycles....especially with the sides that come with caber, I'll never touch that stuff again
I've used it on PH cycles and during PCT. Be sure to ween yourself off of it, I personally think you get a little estrogen rebound if you go from 5 squirts twice a day to none. But, it very well could depend on the person.
