I've just made a concoction consisting of garlic, onion, and olive oil. I made about 12 ounces using 12 ounces of olive oil, 4 tablespoons of garlic powder, and 4 tablespoons of onion powder. I let it simmer on low heat for 20 min, then transferred it to a glass jar. I plan to take 2 tablespoons in the morning and 2 more in the evening. I've read that the 3 ingredients can raise testosterone and libido, so I'll see what happens.
