Ephedra is very popular and many who have taken it say that it works. But, it also has serious side effects and can damage your health. So, it has been banned. But, due to continued high demand, many people are ordering it on-line from foreign sources.

There are also many versions of Stimerex available that do not contain Ephedra. So, be sure you know what you're getting before you buy. Also note that in some cases the law limits the amount of ephedrine to 25mg, which is less than pills like this used to contain.

Stimerex uses Sida Cordifolia Extract for its source of ephedrine. It's genetically engineered.

Stimerex also contains a number of other natural-derived herbal ingredients like:

Citrus Aurantium Extract - Also known as "Synephrine", which is a chemical cousin to ephedrine. It is said to enhance the effect of ephedrine when the amount of ephedrine in the pill is limited.

Green Tea Extract - Many studies have shown the healthful effects of green tea. Also, it acts as a stimulant which reduces your appetite and helps you burn fat by increasing our metabolism.

Naringen - This ingredient allows the other stimulants in the formula to work longer, by slowing down the rate at which they metabolize in your body. Thus, it enhances the other ingredients, including the ephedrine.

Here are the complete list of ingredients of "Stimerex-ES with Ephedra 90 Caps by NutraSport": Sida Cordifolia Extract 25mg, Caffeine 200mg, Acacia Rigidula 70%, Theobroma Cocoa Extract, Phenylethylamine HCL, Citrus Aurantium 30 % Extract, Yohimbe Extract, Naringen, 6 - 7 Dihydroxy Bergamottin, Green tea extract 80mg.
