I purchased my Alli on Ebay also for a cheaper price. My Alli was Real. The Bottle was Sealed and It was Listed as New on the Listing, Some Sellers on Ebay Open the Bottle and Sell sample packs and shop them in a Ziplock bag for you. Don't Purchase them! That's when your at Risk of Buying Something Fake or Contaminated. I wouldn't purchase those because they touched them and it's Not Sealed by the Manufactor. Make sure the Sellers feedback is good too, . At first I had no Side affects or Treatment Affects for the first week, Than They came and went away, It all depends on what I eat, If I eat right, I have no treatment affects, If I eat more fat than usual, Thats when I experience the Treatment Afects,, It's Great that means its working,
My Plan is I diet or Eat Right Mon-Fri and take Alli with every Meal 3xper day,, with Moderate Exercise
On the Weekends I usually treat myself and eat what I want but, in moderation, (Including Fast Food)
So far I lost 3lbs in 3weeks
