If you scroll down to the manufacturer chart on Manly at this link marylander furnished, they show the pharmaceutical manufacturer names for each generic sildenafil which All Day Chemist sells. In the case of Manly, which marylander knows works for him, it is Cooper Pharmaceuticals in Delhi, India. My generic of choice, Suhagra, which has never failed me, is manufactured by Cipla, also in India. Obviously, what works for marylander and for me, may not necessarily work the same for everyone else, since all body chemistries are different.
It's true, as Gman states, that these manufacturers are not controlled by the FDA, (or any U.S. government agency) but back in the days before I began this hobby, when my sexual adventures were somewhat seldom and sporadic, I had a standing prescription through my GP for Viagra which was 4 tablets for anywhere from $95 to $115 whenever I filled it, which wasn't that often then. Once I began hiring numerous guys and sex became a regular happening, I was very happy to see All Day Chemist referenced on the forum by a member here whose posts I had always respected. After ordering a small amount of Suhagra to see if it really worked (for me!) I was ecstatic to find it so effective at such a reasonable cost, leaving me more money for my hot escorts! :)
