"it&#039;s a god&#039;s gift for me...i am a male 25 years old.. i wasted my 4 years of several face wash and different pills but nothing works... at last i decided to take this drug when starting i take 40mg for a day.. but 40mg is over dosage for me. it causes severe side effects like lips  full red and face turn into black... i really disappointed..and then after one month everything turns back to my normal. by that time i noticed my acne is gone.. and then i decided to take 20mg for a day..yes this is the correct dosage for me and without side effects... only lips are chapped that&#039;s all. i am using this now 33d ays finished now i am feeling ok..."
