While psychological effects and increased libido may occur within weeks, effects like changes in body composition like fat loss and muscle mass may require longer time-frames.

Effects on Muscle Mass/ Strength

Studies have shown that testosterone therapy is capable of increasing muscle mass within a few weeks of administration. The degree of effect that this kind of therapy has on muscle mass and strength is hugely dependent on the dosage and frequency that the therapy is conducted with. If the dosage of testosterone is very low, there may be no noticeable effects to muscle mass at all. Research indicates that some muscles are more responsive to testosterone therapy than others.

Lower body muscles like thigh muscles and quadriceps show increases within 12 – 16 weeks depending on the dosage. Skeletal mass and general power has seen to increase over a 180 day span. Lean body mass shows significant positive change within 6 months. Therefore, it can be said that the therapy’s effects include noticeable changes within the first 20 weeks, showing maximum effect between the 6th and the 12th month.

Effects on body composition

Testosterone therapy has also been shown to reduce obesity and weight-gain by increasing lipid metabolism. While body weight, sometimes, may remain unchanged due to an increase in muscle mass, increased levels of testosterone lead to a decrease in fat stored.

Typically, a decrease in total body fat content is registered after 3 months of going through testosterone therapy. This may differ from patient to patient but it is generally assumed that noticeable decrease in fat occurs between 3 and 12 months. This is likely to continue at a slowing rate over the course of 2 years, assuming that the therapy is continued.

Effects on blood pressure

Testosterone therapy has been shown to cause cardiovascular effects and decreased blood pressure between 3 and 9 months. A reduction in arterial stiffness is noticed within just 48 hours and it improves over the course of 3 months. Exercise capabilities of patients with heart conditions improve significantly after approximately 12 weeks. However, it must be noted that when a testosterone dose I too high blood pressure can increase.

Effects of libido

Testosterone is hugely connected with a patient’s libido, sexual desires, and sexual capability. Testosterone therapy is said to cause increased sexual desires, stimulating a patient’s libido within just three to four weeks. This increase grows at a declining rate for about three months.

With regard to erectile functioning, effects have been seen to manifest themselves within 3 weeks to 3 months. Maximum effects are seen after a period of 3 – 6 months of testosterone therapy. In some cases, these effects may be observed close to a year.

Effects on quality of life

A patient’s quality of life is generally measured by conducting surveys and using questionnaires, where patients answer questions regarding their present states of mind. It is also hugely connected with one’s libido and sexual desires. Surveys show that patients show noticeable changes in their dispositions from one month onward and this could continue over a period of 9 -18 months.

Effects on psychology

A patient’s psychology is determined by their predominant moods and their motivation levels, among other factors. Studies have shown that testosterone therapy and increased testosterone levels caused an improvement in patient’s moods over a 3 – 4 week span. Patients noted that they felt the therapy combating depression after around 3 – 6 weeks. This translates into increased sociability, reduced anxiety, increased attention spans, and increased confidence. Fatigue levels also show improvement after a month.
