Be careful with synthol. . .
Quote by Dan Duchaine when asked if he feels synthol use is safe long term
"No, I don’t. But I can’t tell why it’s going to be unsafe. My gut feeling is that something bad is going to happen. I have a feeling the reason the oil doesn’t dissipate is somehow…. It’s hard to believe that an oil would stay in an area for months at a time unless there is some kind of collagen encapsulation going on, where the body is protecting itself from the substance. It would be just like a breast implant—smooth ones that don’t have the ripples and [contain] collagen."
Another reason to stay away from synthol
Quote by Michael Furci
"Milos Sarcev, a well-known professional bodybuilder, collapsed suddenly while injecting his bicep. The oil went through his circulatory system and collected in his lungs. He basically started to suffocate. If his wife were not there, he would be dead."
All I have to say is be careful if you're gonna take that risk.
