Did everyone forget the article Eric wrote about how toxic nolva and clomid are in being linked to causing cancers and cataracts on the eyes. You have to remember the word "selective" in SERM's in some receptors they increase estrogen and in others they block it.
This is why in the uterus it will increase estrogen and thus "uterine cancer" i know this is in females but this will cross over to male prostates and this has been shown in rat studies in the prostate and also cell lines.
Now i know some people are going to say yeah but we use it for short periods of time but it causes toxic changes in the endometrium within 24hrs of the first dose.
