Bests & Worsts Reviews from Amazon

This product has very strong procedures to authenticate the product. You can be absolutely certain that this product is on the FDA list and that it is not a fake. I went directly to the FDA website and verified that POWECOM was an approved manufacturer. When the product arrived I wend directly to the POWECOM website to authenticate the product. On the the product packaging you can reveal a 20 digit number, the same way you scratch a lottery ticket. I entered the 20 digit number and confirmed that it was authentic. I entered the exact same number a second time, and I was told that the number was valid but it had been entered previously. I guessed several 20 digit numbers, all of which identified as invalid.
