I purchased 20mg Accutane and 0.05 mg Retin-a. When I started on the Accutane I thought it was fake because I didn't feel the same symptoms (dry lips and eyes) like I was used to. I increased the dosage slightly and then started to feel the dryness come on. So maybe the dosage is slightly less than 20mg, but still ultimately effective. The retin-a immediately started the expected peeling, so that was never in question. Customer service is not Zappos-level; terse and not very helpful. My first order of Accutane was only 30 pills so I could test it out, so I tried to order more. The product has been discontinued and the customer service rep said she didn't know if they would be getting any more. I've monitored my credit card usage closely, no nasty extra charges. Package arrived within 2 weeks, registered mail.
