This product is a rip-off. Save your money. I have had the worst headache and stomach ache ever since taking this product. I am in so much pain. You will go right to your health club if you want that feeling of having just went on an acid trip. Please save yourself the agony - don't buy any products from Pure Bliss Nutritions! They are scammers who would sell poison even though there was no evidence it has harmed humans. The ingredients are completely untested. Do not buy.
