What is Testosterone Undecanoate?

Testosterone Undecanoate (Ultra-long-acting esterified testosterone (injectable)) is a testosterone undecanoate ester — C₃₀H₄₈O₃, MW 456.7. Longest-chain testosterone ester providing ultra-extended release (peak ~7 days, active ~10–14 weeks in clinical use). Stored in lymphatic depot before systemic release. Free testosterone activates the androgen receptor (AR). Minimal aromatisation relative to shorter esters at equivalent free-T levels.

Research Applications

Ultra-Long-Acting Androgen Depot

Lymphatic depot storage and extended-release pharmacokinetics research

TRT Research Model

Androgen Receptor Biology

AR binding, nuclear translocation, androgen-responsive gene expression

HPG Axis Feedback

Prolonged suppression kinetics of the hypothalamic-pituitary-gonadal axis

Lymphatic Drug Delivery

Lymphatic absorption model for lipophilic injectable depot formulations
