Side effects review when use Triiodothyronine T3 for bodybuilding

Triiodothyronine T3 is not an anabolic steroid, but it plays a similar role to anabolic steroids to some extent. Although it is a drug used to treat hypothyroidism, but as a hormone (thyroid hormone),  use T3 for bodybuilding, there will be corresponding side effects.

Thyroid axis inhibition

The first is the inhibition similar to that of anabolic steroids. Exogenous T3 inhibits pituitary secretion of thyrotropin hormone (TSH) and thyroid secretion of thyroid hormone through negative feedback mechanism, and long-term inhibition of thyroid axis may lead to thyroid dysfunction. Heavy use of exogenous T3 may lead to hyperthyroidism, especially an overactive thyroid with symptoms such as rapid heartbeat, anxiety, sweating, weight loss, and fatigue.

Bone loss

Triiodothyronine T3 promotes skeletal muscle use of minerals such as calcium and phosphorus, which helps bone growth and development. Long-term use of it may lead to decreased bone density and an increased risk of osteoporosis and fractures.

Metabolic disorder

T3 causes the metabolism to accelerate, resulting in rapid weight loss, increased heat production, and excessive sweating. If you do not exercise, the breakdown of muscle proteins will occur, resulting in muscle loss.

Heart problem

T3 also has an impact on the cardiovascular system, leading to increased heart rate, palpitations, high blood pressure and an increased risk of arrhythmia. These effects can be especially dangerous for people who already have heart disease.

Sleep problem

T3 increases the basal metabolism, which can cause problems with excitement, insomnia, light sleep and more.

Psychological influence

T3 use can also affect mental health. Some people may feel anxious, irritable, mood swings, etc. These psychological side effects from T3 may sometimes affect normal work and life.

The thyroid hormone T3 is a powerful hormone that plays an important role throughout the body, and care should be taken to test the level of thyroid hormone in the body at any time during the use of T3. At the same time, do not overuse T3 for a long time to avoid serious side effects.
