"i was issued this when i went to afghanistan to prevent malaria. i didn&#039;t take it like many of us in my unit. ever since moving to georgia and joining the military i&#039;ve had acne, it breaks out very badly. my medic overseas asked me if i was taking my doxy and i told him i wasnt. he let me know that it was commonly used as acne medication and that&#039;s when i started using it. 100-200mg per day after a few days completely cleared up my skin, after a week i looked like i did in highschool i&#039;ve never been happier and th rest is history, i highly recommend this product"
