MAXMAN IV is an impressive herbal product that I have used many times. Effectiveness is said to last more than 24 hours. Sometimes longer for some people than others. I tested this, and from my experience I would say that I can not say that the the claim made was untrue. For an herbal enhancer, MAXMAN IV will definitely impress.
Another great herbal product available for recreational sexual enhancement that will definitely impress, lasts long–don’t waste it!
