Greetings from a fellow cyclist. Good to hear you're doing well. Good info in your post except for the myth about low SHBG leading one to "piss out most of the testosterone you inject, it passes quickly through your system." If you and your normal-SHBG twin are each injecting 70 mg TC per week then you are both metabolizing and excreting the same amount. The rate for both you and your twin is determined by the absorption rate of the testosterone depots, which is unaffected by SHBG. Free testosterone is the same for each twin. If there's a grain of truth in the myth, it lies in the speculation that low SHBG leads to faster intracellular metabolism of testosterone; a shorter residence time for unmetabolized testosterone in that environment would mean that less testosterone is put to work doing useful things.... I’m 55, lean, very active cyclist, still beating guys half my age.
