Synthol is composed of 85% medium-chain triglyceride oils (a fatty acid), 7.5% lidocaine (painkiller), and 7.5 5 benzyl alcohol. The preparation is injected deep into the muscle where it is encapsulated between the fascicles (bundles of muscle fibers) .
It is a steroid, a legal anabolic steroid but an injected steroid nonetheless. Thanks anyway

I suggest maybe you make that dash to google yourself
