Sorry, I haven’t been on here in ages. I can only speak for myself and my friends and family that have tried C60. I am making it myself so I know how expensive the raw material is, So anyone who sells it for around 50$ cannot be putting in the full concentration or uses low purity raw materials from China . It has helped me and so many of my friends with the symptoms of aging and a lot of chronic and autoimmune diseases. There is the odd person that doesn’t feel anything. Maybe if you’re very young or very fit and healthy but even athletes notice a performance boost. So my best guess is that the product you are using is just with little or no C60 in it, you know the world is a bad place sometimes and there are a lot of insincere people around.
