Synthol (Pump-n-Pose) is a non-anabolic drug used to locally increase muscle volume and give it an ideal shape. The drug was developed by the German chemist Chris Clark in the 1990s. It is especially common in professional sports before competitions. The name “synthol” occurs by analogy with the nuclear fusion reaction, but this name was already patented, so later the synthol began to be sold under the Pump-N-Pose brand (“pump and pose”). Original Synthol is officially positioned as an oil for posing with the word “site enhancement oil” for unhindered distribution.
