I ordered Active-PK because it is designed to address deep visceral fat, something I have to deal with. I started taking it and my wife noticed the effect. I experienced no side effects or problems at all. I try to avoid anything that elevates my blood pressure, I also am pre-diabetic. My weight dropped, my blood pressure was sable and my blood sugar was stable. Most important, my belly diminished and I dropped a few waist sizes in my pants. I hope to continue this success into the future.
