The tadalafil has been my golden child so far, i have been running that at around 5-7 mg per day more as a test, to validate some research i had looked up as to the benefits of daily low usage of it and have to say im quite impressed, Feeling the pumps and definitely noticed the increase blood flow in other areas :) .. I too on a special occasion had dosed up on the Sildenafil, to make sure it was working as well, and it worked just as well as the real deal since i got o prescription for those as well!! so if anything thats money in the bank for me!! The only product i have yet to try as of yet is the Dapox, since im not planning on having an orgy or time coming up soon to where im gonna need to go for a while, however i got it on hand for that future planned session!!! But i have no doubt this is good to go!!
