I purchased a 12 session pack from Hypoxi and I was really surprised at the results. Due to being small in stature, I wasn't really expecting much loss, however at my 12 week weigh in, I was so so Amazed at the results I got. It truly was amazing how much I really lost.
I did stick to the hypoxi guidelines and was very happy with the results. I have since purchased another 6 sessions and am also doing weekly maintenance.
