Gurki, the standard dose is 20mg, but I suggest you start with 10mg and see if that works for you. If you really don’t have ED and are just using the product as an experiment, or as a work out enhancement, then 10mg should be plenty. By starting low you can always adjust up to the dose that’s right for you. If you start high, you have no clear indication of how much is enough, or too much as the case may be. Too much of any good thing can be bad, plus this will keep you from wasting your product unnecessarily.
