Nelson was just making shit up again for the sake of trying to win an argument, the dude has an enormously unjustified EGO.
J/K, but if Nelson is being honest, 900ng/dl is not supraphysiological by any means and will not provide muscle or strength gains, although it will probably increase his libido--IF those numbers he reported are indeed accurate. I am sure he will be able to have enjoyable workouts, but that is not an optimal HRT dosage for a recreational bodybuilder. If you are using HRT SOLEY for quality of life, then Nelson's dosing protocol could be valid.
As for Free Testosterone, everyone will always have a different ratio of Total:Free T. In addition, SHBG levels increase for numerous reasons, and by reducing circulating levels of SHBG, we can further increase FREE T in the body, which generates a PROFOUND effect ESPECIALLY when using supraphysiological dosages of testosterone. For this reason, Test(2) + Proviron(1) = MAGIC(4). That is the beauty of SYNERGISM.
