Here are a list of possible virilization sides: (taken from the above thread)
"First, steroids are MALE hormones. AAS stands for Anabolic and Androgenic Steroids. There are present in the female body but in minute amounts. When you supplement with AAS, even mild compounds, you run the risk of developing side effects. There is NO SUCH THING as a side-free compound. There are some AAS that are milder, but they all have to potential to cause unwanted side effects.
Before you think about a cycle of AAS, you need to be aware of the possible side effects that you will have to live with for the rest of your life. Most of the side effects are IRREVERSIBLE. Here is a list of possible side effects: compromised HDL/LDL levels, acne all over your body, increased blood pressure, breast shrinkage, loss of menses, water weight gain, dry scalp, oily skin, hair loss, enlarged or sensitive clitoris, increased sex drive, voice changes (starting with raspiness and going further into deepness), coarser hair, increased hair growth (everywhere), darkening of previously light/blonde body hair. Additionally, there is the possible chemical changes that can occur to your supply of ovum. There is no data as to how AAS will harm a yet to be conceived baby (i.e., birth defects). These are just a few. Some may not seem like a big deal now, but remember, you will have to live with them the rest of your life."
