Very effective and easy to use. Viagra has revolutionized how ED is managed. Sex is great now, even for a college guy. It's not the only thing to solve impotence. I alternate with injections.
Product woks much of the time.
Its cost is criminal. I have used Viagra and find it easy to use, and very effective. Having tried Viagra in 100mg doses, I found it does about what it had been claimed to do. Truely a wonder drug. Seems to be popular with middle aged men, an age which I haven't yet reached.
