200 mg tablets of Caffeine. I lost my sense of taste after taking these. I reported the occurrence to My Protein, it was agreed that I should return the product. They sent me a Returns Label which I used, the item was received 2 days later. My refund.....go on, I dare you to guess?!!? So, several weeks later, not a word from them and no refund. I did use PayPal and will use them to expedite the missing cash. DO NOT GO CLOSE TO THIS OUTFIT. I lost my sense of taste for a full week. I would not like the same OR WORSE to happen to someone else. YOU HAVE BEEN WARNED!!
