Massive shed after switching Finasteride to another source.

Shedding after switching Finasteride supply source may reflect a counterfeit drug or a faulty production lot. Check the source and go back to where you originally got it from. I have seen this even in good stores when they purchase off-brands of genetic finasteride. Hair loss from Finasteride withdrawal may become permanent so act quickly and get back to a source you can depend upon.
