Basic description of the active ingredient Testosterone Undecanoate

Testosterone undecanoate is a synthetic form of natural testosterone used in sports and medicine. From a pharmacological point of view, the ester promotes continuous stimulation of the muscle hypertrophy process. Undecanoate is the longest-chain form of testosterone, and the effect of the substance in the body lasts up to 15 days. This allows athletes to take injections less frequently.

Testosterone undecanoate injections have a half-life of 21 days. For safety reasons, it should only be used by those with experience in taking steroids.

Indications for the use of testosterone undecanoate

The reasons to buy testosterone undecanoate are related to the effects that this ester has.

  1. Stimulation of muscle hypertrophy, allowing you to gain 6-10 kg of pure muscle mass in just one course.
  2. Increase in strength indicators by an average of 10-20 per cent.
  3. Strengthening of bones: improved mineral absorption makes them stronger.
  4. Reduction in recovery time.
  5. Strengthening of the immune system.
  6. Elimination of joint pain thanks to the renewal of synovial lubrication.
  7. Increased endurance due to oxygen retention and increased red blood cell concentration.

According to reviews of Testosterone Undecanoate, this ester also helps reduce body fat. When Testosterone Undecanoate begins to work, fat is transformed into waste and nutritious fuel for the needs of muscles and organs during lipolysis.

Testosterone undecanoate: how to take it

Before injecting testosterone undecanoate, athletes are advised to undergo hormone testing at a clinic or medical centre.

Depending on the state of health, the complexity of the tasks, the type of therapy (solo or combined), age and experience with steroids, an individual programme is drawn up. If necessary, the expert may prescribe additional supplements.

The standard duration of a testosterone undecanoate course is 6-8 weeks. For the first cycle, it is recommended to limit yourself to one month in order to prepare the body for longer programmes. The weekly dosage should not exceed 500 milligrams. Restorative therapy is mandatory.
