SQ would be a waste of time as inj l-carnt doesnt spot burn fat. That's not how it works. L-carntine transports the fat accross the mitochondria to get burned. It has to be IM in order to reach the blood stream properly so it can do that. L-carnt itself doesn't burn fat, it only carries it to be burned by the other
fat burning drugs you are taking, although the l-carnt is the limiting factor when it comes to how much fat you burn - you wil only burn as much as it was transported.
