There are many reasons people decide to buy sex hormones. Some of the reasons are:
to increase sex drive (the product has to have at least 1 of the following to be a good product): This is a popular sex hormone. It has a very low cost per dose (less than $10 per month for a 1,000mg dose). You might want to get 1,000mg to see what effects it has. If it doesn't have much effect or your hormones are not doing what you expect, you might want to consider taking the hormone 2 months in a row. If you want to increase sexual desire, take a low dose of estradiol. You'll still get a significant improvement in sex drive. There's even some research that shows that this can increase your libido. If you're a bit low on estrogen, take a very low dose of testosterone. It won't make you infertile (no need to worry about this if you want kids) or make you "faster". If you've had a vasectomy, take testosterone with T, and you'll be able to get a vasectomy. If you're on oral contraceptives, there are more pills that can be taken to get a good effect, as they do have the side effect of increasing your risk of heart disease.
