Doing so reading I found that Turinabol can bind to the SHBG protein which then prevents testosterone from binding to it. This frees up more testosterone to circulate. This property of Tbol is what makes it appealing to bodybuilders, rather than any direct performance enhancing or growth effects. Turinobol can help other compounds like Deca work more efficiently. Does anyone else have some info on what compounds bind more to the SHBG protien?
