If you have been using our Vanadyl Sulfate and getting results, now there is something even better; Advanced Chromium KIC. The fact is that Chromium Picolinate has a US patent and is highly documented, proving it is by far, much better than Vanadyl Sulfate, KIC (ketoisocaproate) is the Keto-acid of leucine and it the most important BCKS-A (branched chain keto acids) Perhaps the most important action of KIC is its stimulation of insulin, Insulin is viewed by many researchers as the most important hormone for producing lean body mass. We do not add Chromium and KIC to Vanadyl Sulfate because there is some evidence which indicates they may interact or be antagonistic. Advanced Chromium KIC and Vanadyl Sulfate can be taken but use Advanced Chromium KIC apart from Vanadyl Sulfate, Chromium Picolinate is scientifically proven to promote a firmer stronger, more energetic body by making your body potentiate accelerating protein synthesis, inhibiting protein breakdown and improving metabolism.
