Product Description:

Testosterone undecanoate is a long-acting form of testosterone. It is dissolved in castor oil and injected deep into a muscle, where it is released slowly. This gives steady testosterone levels for about three months, without the peaks and dips of older weekly or fortnightly injections.

It is used for men with confirmed low testosterone (hypogonadism). After the first two doses, given a few weeks apart, injections are spaced every 10 to 14 weeks. The injection must be given very slowly, as the oil can rarely enter the bloodstream and cause coughing or shortness of breath. Blood counts, prostate health and testosterone levels are checked during treatment.

Sourcing notes. Generic versions are available in several markets, and US generic entry for the 750 mg product is expected from 2027. Testosterone is a controlled substance in many countries (for example Schedule III in the US), so buyers need the right import licence and permits; we check this before quoting. Store at room temperature, do not refrigerate.
