This can help improve the symptoms of low testosterone, like low libido and lack of energy. With TRT, you take a manufactured form of testosterone to regulate your levels. Before starting TRT, your healthcare provider will make sure low testosterone is an accurate diagnosis. As of 2025, it’s not yet approved for males who naturally experience a decline in testosterone as they age. Understanding potential side effects, exploring mitigation strategies, and committing to a holistic approach are critical. Consulting a knowledgeable medical professional is crucial for guidance. Deciding to come off TRT after six months is a personal one with potential implications. Given these potential risks, discussing long-term implications and individual risk factors with your doctor before starting or stopping TRT is crucial. During this time, testosterone levels may drop very low. Even after hormone levels return to normal, it can take extra time for the body’s tissues—muscles, bones, and the brain—to fully adapt. For some, it can take up to a year or longer for natural testosterone to return to a healthy range. Natural testosterone levels often rise during this time, although they may still be lower than before TRT began. There are several natural supplements which may help to support testosterone levels during this transition, although the increase in T production may be slight, especially in comparison to prescription testosterone. Additionally, a healthy diet, regular exercise, and stress reduction can positively impact libido over time and may be needed to combat the lower suboptimal testosterone levels. However, resistance training can help you retain muscle and even stimulate some natural testosterone production but expect to lose size and strength as well as definition. One study of older men found that TRT’s effects on body composition, muscle strength and quality of life had worn off six months after stopping treatment. But it can be months before your body recovers from its effects and your T returns to pre-treatment levels. Our data-driven approach means you’ll know — with numerical certainty — whether your body has successfully restarted natural testosterone production or whether resuming therapy is the medically sound choice. When on TRT, the body’s natural testosterone production often decreases because the pituitary gland senses sufficient hormone levels. Because TRT affects the body’s hormone balance, it can also cause the body to reduce or stop its own natural testosterone production over time. During therapy, the body often slows or stops its natural testosterone production because it senses that enough hormone is already being supplied. Testosterone therapy, often called TRT, is a medical treatment used to increase testosterone levels in people who have lower than normal amounts of this hormone. A combination of resistance training and cardiovascular exercise is effective for maintaining a healthy body composition/BMI and will help maximize the body’s natural testosterone production. After a period of time, these may help boost T levels and help increase natural testosterone production as well. Post-cycle therapy (PCT) involves medications or supplements that encourage the body to restart natural testosterone production. Once the individual has discontinued TRT and the body has had time to adjust, it is important to monitor hormone levels to ensure that testosterone production has resumed. To support the body’s natural testosterone production during this time, individuals may be prescribed medications such as clomiphene citrate (CC) or tamoxifen citrate (Nolvadex). However, long-term use of TRT can lead to suppression of the body’s own testosterone production, making it difficult for the individual to discontinue therapy and resume normal hormone levels. The HPTA (hypothalamic-pituitary-testicular axis) restart protocol is a method used to help the body resume its natural testosterone production after discontinuing testosterone replacement therapy (TRT). Often we have patients Discontinuing TRT is sometimes necessary for men looking to restore fertility, however there are medications that can help maintain fertility when on TRT like enclomiphene, FSH, LH and hCG. Things like diet, sleep, exercise and stress management may help increase testosterone and for some patients this may be a suitable course of action. Patients that may have preexisting heart conditions or prostate cancer may not be good candidates for therapy. While these are often manageable, they can sometimes prompt discontinuation. TRT is designed to be a long-term treatment. Do you have to stay on testosterone once you start? If you stop, your T levels will go back to what they were before. Some people experience low mood, irritability, or anxiety after stopping testosterone therapy. When testosterone therapy ends, the body’s hormone levels drop. Exercise plays a key role in recovery because it boosts natural testosterone production and improves mental well-being. Stopping testosterone therapy (TRT) is not only about changes in hormone levels—it also affects how the body and mind work together. With patience, medical supervision, and healthy habits, most people can expect their hormone levels—and quality of life—to return to balance over time. In the first days and weeks after stopping therapy, the body experiences a quick drop in circulating testosterone levels.
