It has natural selective estrogen receptor modulating properties, not strong enough for M-Drol IMO. As previously mentioned, M-Drol is tricky. Without a baseline and post cycle bloodwork there is no way to tell how shutdown or how recovered you really are. This is why people tend to overkill their PCT on M-Drol. I would probably suggest you go with at least 10 mgs/daily of nolva for a couple weeks.
