I purchased this supplement for the improved circulation potential. I have to say I am not disappointed in the product, though I am not sure it in fact provides all of the benefits it claims. So it depends on your motivations whether or not you will be satisfied with the product. I have experienced some days temporary significant flushness about 30 minutes after taking the pills. Nothing of concern, just interesting. Overall, if you are seeking this supplement, I have nothing negative to say about it.

I have been taking this as directed and I really didn’t see any difference in anything. I am not sure what I was expecting but I had no kind of energy boost, no sustained nothing really. I can’t say anything bad about the product but I also can’t say andything good.

Excellent product. I use right before a workout. I feel it immediately. With this product I don’t need to use a pre-workout. I’m 50yrs old and I’m benching 350lbs. I was using these ingredients separately but with the combination in this product it is much easier and less expensive.

My husband loves this stuff to help make his workouts better. It does hurt his stomach a little but he seems to do better when he eats with it, but he keeps using it so it must not be that bad. Haha

When I take one pill, I can actually feel it build my heart rate within minutes.Not harmful as it’s based on food. Clears out my arteries in my legs and I can feel blood pumping through them.
