Kyzatrex (testosterone undecanoate) is classified as a Schedule III controlled substance in the United States because it contains testosterone, an anabolic steroid with potential for abuse [1.2.4, 1.3.7]. So, is Kyzatrex a controlled substance? Yes, and its regulation has significant implications for patients and prescribers.

Most testosterone formulations should be stored at a controlled room temperature, typically between 68°F and 77°F (20°C to 25°C) [1.2.2, 1.3.2]. The critical question of 'does testosterone need to be refrigerated?' is a common concern, and the answer is almost always no.
