The rating is on a 1-10 scale and is more for what you should use the product for, not the results in that category. For instance a 5 in nitric oxide means do not purchase if pumps are your main concern from the product. A 10 in training intensity means if you are training for intensity, nothing legal is better. These all rate 8 for recovery. The best recovery product available is NOS ETHER. I would use with NOS ETHER if you train at over 80% max capacity at least 3 times a week. Competition/professional level training. Everyone else should be ok with just one of the above if you are looking for an "all-in-one" category product (pumps, energy, and recovery).
