Ingredient list: Lipo-C is a compound containing a combination of Methionine, Inositol, Choline, Pyridoxine B6, Cyanocobalamin B12, Methylcobalamin, L-Carnitine, and L-Arginine. All such good stuff. LIPO C can be injected sub-q or IM. IM is best, your muscle can hold more of the liquid and it just seems like there is better bioavailability.
