Product Description:

Mestanolone, also known as Methylandrostanolone, is a potent synthetic androgen and a 17α-alkylated derivative of dihydrotestosterone (DHT). This compound is widely used in academic, sports science, and biochemical research due to its strong androgenic properties and high oral bioavailability.

It is not aromatizable, making it a preferred candidate for studies focused on androgenic pathways without estrogenic influence. Mestanolone is structurally resistant to metabolic breakdown, giving it a long shelf-life in in-vitro and in-vivo models.


🔬 Applications in Research:

  • Study of androgen receptor binding

  • Analysis of muscle protein synthesis pathways

  • Investigation of neurosteroid effects on behavior and cognition

  • Evaluation of liver metabolism and hepatotoxicity

  • Comparative studies with other 17α-alkylated androgens
