Testosterone Enanthate API – Technical Guide for Global Pharmaceutical Buyers

Testosterone Enanthate API is a long-acting ester of testosterone, a naturally occurring androgen essential for male development and overall hormonal balance. In pharmaceutical manufacturing, it is formulated as an Active Pharmaceutical Ingredient (API) primarily for hormone replacement therapy (HRT) and certain medical conditions requiring sustained testosterone delivery. Amber Lifesciences produces and exports pharmacopeia-compliant Testosterone Enanthate API, manufactured under GMP and ISO 9001:2015-certified facilities for global pharmaceutical partners.

Testosterone Enanthate API Chemical & Physical Profile

  • CAS Number: 315-37-7
  • IUPAC Name: [(8R,9S,10R,13S,14S,17S)-17-hydroxy-10,13-dimethyl-1,2,6,7,8,9,11,12,14,15,16,17-dodecahydrocyclopenta[a]phenanthren-3-yl] heptanoate
  • Molecular Formula: C₂₆H₄₀O₃
  • Molecular Weight: 400.6 g/mol
  • Appearance: White to off-white crystalline powder
  • Solubility: Dissolves well in organic solvents like ethanol and oils; exhibits poor solubility in water

After administration, Testosterone Enanthate is hydrolyzed, slowly releasing free testosterone into the bloodstream, ensuring a prolonged and steady physiological action.

Pharmacokinetics & Usage of Testosterone Enanthate API

  • Half-Life: Approximately 7–10 days (due to the enanthate ester)
  • Route: Intramuscular (IM) injection in oil-based solutions
  • Peak Serum Levels: 24–48 hours after administration
  • Detection in Anti-Doping Tests: Up to 3 months post-use

This extended release profile makes it a preferred choice in HRT programs and other medical protocols requiring steady hormone levels.
