I use the Vardenafil Manufactured by : Cooper Pharma, India. These work the best for me. I have tried Ceebis they work good, I have tried Manly they did nothing for me. I also tried a sublingual Viagra compounded by my Doctors pharmacy hardly did a thing.
For me the Vardenafil works the best, then Ceebis, I also have a sublingual Cialis compounded that works good. But the Vardenafil from Cooper works the best. If I take 2 teaspoons of Arginine from NOW with the Vardenafil my wife is very happy.
