The product is not a Nitrous Oxide expander, its simply inceases oxigen to the blood.The enzymes he listed can increase oxigen in the blood, Also this product has the enymes to break down protein, so the body absorbs all the protein you take in alot more efectively Another positive thing about this product also is it has the enzymes to assist the body in the breaking down of fats and carbohydrates, so the body workks work effeciently .There is also enzymes in this product that will stop infalmation from occuring, and if it does occur, it will take down the inflamation .This product seems like a solid product once I have seen the ingredients, and how it was designed.I will say this if you take this product with a nitrous oxide product it will literally triple the effects what ever N.O product you take with it.Who ever designed this product was no dummy, it was well thought out.You guys can bash this produxct alll you want but if you really knew how it worked, you would see that the product is something 90% of the bodybuilders out there can use.It increases oxigen, helps the body breakdown protein, fats, carbs, and can stop or eliminate infalmation of damaged tissue.What bodybuilder couldnt use this product? Any smart bodybuilder would see this product has everything most bodybuilders over look, thats why they have bloating , injuries, and sometimes dont get a pump.This product was designed for bodybuilders who use there brain, and there brawn........Good product Jimmy I give it a thumbs up
