Horny Goat Weed powder is all natural, but it’s also powerful. It is very important not to take too much. For best results, you should take ¼ teaspoon in the morning, and another ¼ teaspoon at night. Remember to take it along with some calories—either mix it in juice or mix it in water and have something to eat. Use a ¼ teaspoon measuring spoon –not the teaspoon from your dinnerware—to make sure you’re not taking too much.
