Be ready for some wicked side effects. This stuff is very powerful and does a number to your body. I recommend taking it seriously and being cautious with your body while taking it.
Muscles and joints are very weak and I threw my back out several times (and i don't have back problems). It takes a good month to see results but my skin cleared up so well. It stayed clear for about 4 mos after taking it and then started back up.
Never to the severity as before accutane. I did take it for a second course about 2 yrs later. Same thing, it came back, but even less. I would recommend this to anyone struggling w/acne but just be prepared.
