I believe you mean "spot" injections - for reducing fat where it's injected sub-Q, such as in ab area and luv handles?
I'll let Big A elaborate on this. I had to try it for a while sub-Q in mid-section. Only localized results were bruising and I still have a few "lumps" that haven't gone away yet.
Site injections are IM injections used to increase size of muscle that it's injected into. Synthetine doesn't do anything in that dept.
