The PH i'm taking (Razordrol) came with this PCT called "A-test" by ANS. It contains 25 mg of 1, 4, 6, androstatriene-3 17-dione, which is a permanent aromatase inhibitor that lowers estrogen and increases Testosterone. But it is said to chemically not be good as PCT because it is expected to interfere with natural testosterone production. But i've done research and everyone that's used it as a PCT says it worked excellent for them. Should I use it as a cycle support or a PCT? Thanks alot!
