alot of ignorance in this thread
It doesn't matter if a steroid can aromatize or not... your own testosterone can be converted to estrogen once you introduce androgens. So you can still get gyno symptoms from non-aromatizing compounds
But either way, taking a SERM doesn't automatically mean your good to go. We take every precaution we can when formulating a PCT, but that doesn't mean what works for one person will work for another.
elevated prolactin can be caused by a variety of things, among which high cortisol is one. Cortisol is elevated after steroid cycles as most know, and can remain so depending on your lifestyle. If your under alot of psychological stress, not getting enough sleep, training too hard etc... this could be you issue.
Also, SERMS are known to decrease IGF-1 levels and disrupt growth hormone levels. Increases in GH are known to increase prolactin and cortisol levels as well, so you could be experiencing a rebound effect from using a SERM.
Or you could be simply playing with your nipples too much, which also can stimulate prolactin secretion and cause you to lactate.
While your endo is very knowledgable and can help you, his first concern is going to be to make sure you don't have breast cancer, which is why he ordered the mamogram. You need to ask him to schedule blood work for cortisol and prolactin to determine if thats truly the culprit, especially before you look into jumping on drugs to lower prolactin.
If you do go the drug route, pramipexole or cabergoline are two used for this issue. Prami would be your best bet b/c it has a shorter half life, and you can stop quickly if you get negative side effects. Dopamine agonists are nothing to play with, and can have nasty sides if you dose them too high or too long.
