It was made for Getting Rid of the Dreaded Double Chin.
As far as I'm aware, there's No Clinical Data on using this for Belly Fat.
The Product is by Kythera Biopharmaceuticals and is called ATX-101.
Don't know of any Reputable Source, although I have seen it being sold by some Research Chemical Companies................... JP
P.S.
Sigma-Aldrich sells it, although I'm not sure if they sell to Individuals.
