Stimerex ES is purported to be the ultimate formula that will finally help you to lose more weight and achieve better results. They claim that bringing back ephedra makes theirs the ultimate formula. They brought back ephedra with the express stipulation that any product use only 25mg for asthma, which is not actually enough to promote any weight loss at all. With this in mind, the rest of the Stimerex ES formula fails to make up for this deficiency. In fact, the rest of the formula actually makes the side effects worse by using an aphrodisiac known as yohimbine. This formula in general is a joke as you can see. It will not promote the weight loss results you are looking for, and you would be far better off using something else.
