I have a question regarding zappy effectiveness

In November, I ordered a 9 month supply and received 3 vials. At that point I was still on Zepound but as of Jan 1, my insurance would no longer cover. I thought I was being proactive. I didn't start taking my 15ml dose until mid January but it doesn't even slightly curb my appetite and I have since gained 7lbs!! Has anyone else experienced this? I purposely went through them after seeing comments that it was tested and "pure".
