Testosterone Replacement Therapy (TRT) is a clinically proven treatment for men with low testosterone levels, known as hypogonadism. Studies show that testosterone levels naturally decline by about 1% per year after age 30, leading to fatigue, reduced muscle mass, weight gain, and low libido.

TRT has been shown to improve energy levels, mood, muscle strength, and sexual function. Research indicates that up to 88% of men report increased well-being after TRT, and it can help reduce fat mass by 6-13% while increasing lean muscle mass by 20% over 6-12 months. Additionally, TRT may lower insulin resistance, benefiting metabolic health.

The UK TRT market is growing, with prescriptions increasing by 45% between 2011 and 2018, reflecting rising awareness and demand. With proper medical supervision, TRT can significantly enhance quality of life while maintaining safety.
