Paravol – From Palo Alto Labs, the Florida/Maine based company behind Aspire 36 Plus and Vazopren, this product is not designed to work in less than an hour, but is designed to work over time. You must take if for about two months for it to kick in as the ingredients are designed to work slowly over time. And they do for many. If you are in no hurry, this might be the product for you. Some top products just take time to work. In fact, the number one rated last longer product Dapovar, takes a few months as well, but its worth the wait. Here too, the wait is worth it for many guys.
UPDATE: It looks like palo alto labs is out of business as their website is now a blank page and we have not been able to get ahold of them.
