I started using Oxiprovin about 2-3 weeks ago. I got a pack of 60 capsules in I think a goodie bag for either the Argus Cycle Tour or the Two Oceans marathon. I cannot actually believe how different I feel after around 2-3 weeks. I am very happy with this product. There is obviously something in your product that my body really needs as it is responding very well to the two capsule a day dosage that I am taking. If you like I could let you know in a month if I am still feeling the same way about this great product. The bottle was in my briefcase for around a month before I decided to try it out. I am so glad I did. Thanks to whoever created this product as it works well. I will endorse this product for you anytime.
