Winstrol and estrogen question

[scarylarry]

My question concerns my girlfriend who is about to start her 1st winstrol cycle. We have both researched the pros and cons but have now found out that she might have low estrogen levels. This is a new twist for us. Can anyone tell us how winstrol usage will effect her estrogen levels, both good and bad. Also, if she needs estrogen therapy to help her, how will winstrol effect that. Any help will be appreaciated.
