Many women have no idea that this is a serious medical issue, and some can end up being very sensitive to the hormone levels in their bodies. As a result, I feel it is important to explain what levels of sex hormones you should be taking and how to use the products. I use the following numbers to describe how high a level of sex hormones is: Follicle Stimulating Hormone (FSH) In women, this is your average level of estrogen (from both the ovaries and from the pituitary). This level of FSH is a safe range. For women with early menopause (menopause is when the normal hormones of your body no longer make the necessary hormones to keep your bones healthy), the level of FSH can be very high. I usually recommend you start with about 1,500 ng/ml. For example, if you're in your mid-20s, you have estrogen levels of about 1,500 ng/ml. If you have low estrogen, you might also be low in FSH. If so, then I recommend starting with about 100-500ng/ml. If you can't find your normal FSH level, then just use a regular injection. Just remember to only use the highest level you can tolerate, as the higher the level, the more likely you are to get an allergic reaction or infection.
