Verified Buyer

Why the warning was mentioned in the description? I bought this product and I read on the label a warning : This product contains a chemical known to the state of California to cause birth defects, or other reproductive harm. This warning should be mentioned on bodybuilding.com website as this is quite scary and one should be made aware of it before buying.


I have been using L-carnitine for a couple of weeks and it is a great fat burner and It is very easy to use!


I've noticed that I have been gaining energy and losing fat..my new favorite product!
