Except their claim is valid, out of the potential millions of users, only a relative few experience side effects. For example, lets say there are 1 million finasteride users and according to the results found in the finasteride trials, only about 5% experienced sides which is 50,000 people. It only seems like a lot of people experience more side effects is because thats what we read on forums, when in reality the average person does not visit hairloss forums and those that do are on the opposites extremes; people who have exceptional results when using finasteride, and those who have had side-effects. These "horror stories" we often see across hair-loss forums are definitely not the norm, as with any drug, prescription or OTC, there are always a chance of side-effects.Yeah, well, Merck also claims the chance of Propecia sides is only marginal - yet here we are.
