I have used them. They did not come with the anti counterfeit stickers, had green pin wheel tops and a strong vaccum. I was assured by a vet who has been around that they were the real deal, so i gave them a shot before kicking up a fuss. End result I retained a bit of water (especially in my face) but did notice fat loss, achy joints and numb hands etc. So i think they were legit. I ran 4-6 iu per day
