Description

Testosterone Undecanoate 300 mg

Product Overview

Testosterone Undecanoate 300 mg is a long-acting testosterone ester formulated as an oil-based injectable solution for laboratory and scientific research. The undecanoate ester provides an extended release profile, making it valuable for investigating testosterone pharmacokinetics, androgen receptor signaling, endocrine physiology, skeletal muscle biology, and reproductive endocrinology. Testosterone Undecanoate is used in approved clinical applications for specific indications and is also an important research tool in endocrine and pharmacological studies.

Key Features

  • Long-acting testosterone ester
  • Active ingredient: Testosterone Undecanoate
  • Strength: 300 mg/mL
  • High-purity research-grade formulation
  • Oil-based injectable solution
  • Suitable for endocrine and androgen research

How It Works

Following administration, the undecanoate ester is gradually hydrolyzed by esterases, releasing free testosterone into circulation over an extended period. Testosterone binds to androgen receptors in target tissues, regulating gene expression involved in protein synthesis, nitrogen retention, skeletal muscle physiology, reproductive function, and endocrine signaling. Researchers investigate these mechanisms to better understand testosterone metabolism and long-term androgen activity.
