It is. Or atleast start it when you are supposed to take your next shot when your levels start to go down and the hormone flucuation begins.
You really need to time out your dosing and also double the serving size per day sometimes for it to work properly. If you begin to get dry flaky skin you can back down on the doseage. Using it with a topical and/cleanser is your best bet in possibly eliminating your acne. I think the reviews will show that it helps people and will steer people away from using harmful drugs. At the very least you want to exhaust other options before using things that can/will damage your body.
