Side Effects from Propecia in Under a Week?

I’ve only taken propecia for 6 days but I’ve noticed some side effects is it possible it could have had such effects so quickly? I’m experiencing erectile difficulties and less facial hair. Age 17.

I could believe that sexual dysfunction might occur as quickly as 1 weeks. Some of the men who are very sensitive to Propecia and get ED or libido problems have reported that the side effect comes on quickly. The loss of acial hair is a new one for me in that short a time frame. If I could get the beard effect without the ED effect, I would love the product even more than I do now.
