Overview
Available as both oral tablets and aqueous injectable suspension. Unusual among injectable AAS: the injectable form is a water-based microcrystalline suspension (not oil-based). 17-alpha-alkylated — hepatotoxic regardless of route. The injectable form still undergoes first-pass metabolism to some degree. DHT derivative — does not aromatize. Harm reduction: Hepatotoxic in both oral and injectable forms. Known for causing significant joint dryness and tendon brittleness (reduces collagen synthesis). Monitor liver enzymes. Notably harsh on lipid profiles. Injectable form is painful due to water-based suspension. Detection time: 2-3 months (injectable), 3-4 weeks (oral).
Mechanism of Action
DHT derivative with pyrazole ring modification. 17-alpha-alkylated. Does not aromatize. Reduces SHBG significantly. Known to decrease collagen synthesis.
