AAS, Lipids, and Estrogen Relationship

Can someone please explain the relationship between AAS and estrogen levels go as far as lipid profiles. In other words, I understand that estrogen levels can affect lipid profile, but are higher/lower E levels protective?.. detrimental? …can properly balancing our E levels while on help to put your lipid profile back into the ‘good’ range.

And while we’re on the subject, how many people believe that the whole “high cholesterol causes heart disease” theory?

Thanks for any input.
