Certainly Noah provides those of us with an erectile dysfunction and who have been seeking treatment / medication from the specialist urology centers in Singapore, a much more affordable option - easily at more than half the price! I can only speak for myself of course and draw from my own experience. Initially I was using Levitra obtained through my regular GP. Then as I was having issues with an enlarged prostate and was seeking treatment at the Urology Center at SGH, I was getting Cialis (Tadalafil) prescribed on a regular basis apart from the medication for BPH. But after undergoing a procedure, I was able to stop taking the BPH medication which makes me dizzy and affects my eyesight. But the Cialis works nicely on a once-a-week basis. Actually the effects of Cialis last longer than the generic Viagra (Sildenafil) - both the positive and side effects as well. Package deal! ;-p Certainly from a cost perspective, I can't complain. For the cost of a one-month supply of Tadalafil from the pharmacy at SGH, I now can have a three-month supply of Sildenafil from Noah. Convenience-wise, it's the same as I can order online and the medication is delivered discreetly; no fuss. I suppose it's also dependent on the regularity / frequency of sexual intimacy with one's spouse. But on a sustained basis, then the cost savings do add up. It's still early days. But so far it's ok. No undue prolonged and adverse side effects. Thanks for keeping in touch and for the follow-up after-sales customer care and support. What I'll be keen on next is whether there is also a cheaper but similarly effective alternative to Priligy (Dapoxetine).
