I would not suggest it. A SERM is only going to block estrogen from attaching from select estrogen receptors. It does not mean that estrogen won't have an effect on your body and a SERM will not stop estrogen from forming and getting very high. An AI will keep your estrogen at a healthy level. Gyno is not the only negative impact that estrogen can have on the body. Also, I find recovery to be much more difficult when you go into PCT with high estrogen.
