What good is it to increase testosterone to higher levels if it isn’t driven into muscle cells? If it just sits in your blood stream it could potentially convert to unwanted hormones, like estrogen. To exert its powerful effects, testosterone needs to be driven into muscle cells. That’s why CryoTest is loaded with another key ingredient that was shown in a 21-day study to increase the number of androgen receptors within muscles. Androgen receptors amplify the uptake of testosterone into muscle cells! By formulating the CryoTest formula with this ingredient, the entire formula is anabolically charged to boost and drive anabolically active testosterone directly into muscle cells! And this is a world’s first! No other testosterone-amplifying supplement can deliver these powerful results! And to further augment the potency of CryoTest, Team MuscleTech™ researchers harnessed another ingredient shown to release another powerful musclebuilding hormone, Growth Hormone (GH).
