Efectiv products are not Informed Sport certified, so if you compete in a tested sport, check your governing body's rules before using any supplement. Every active ingredient and its dose is printed on the label.
Some brands list ingredients without saying how much of each is in the tub. We list every active ingredient with its exact dose, so you can check the amount before you buy. Where a product uses a branded blend, such as PeakO2®, we say so.
