Also known as
Aromasin hCG: Ovidrel
Aromasin is a selective oestrogen receptor modulator. It is an anastrozole-based anti-estrogen that suppresses aromatase activity and lowers circulating oestradiol levels. Athletes use it to manage the oestrogenic side effects often associated with exogenous androgens. SynthesisGear stocks this compound under a single product, the Gain Mass Course from Magnus.
Core Function
Aromasin acts as an aromatase inhibitor. It blocks the conversion of androgens to oestradiol, thereby reducing systemic oestrogenic activity. This pharmacological profile makes it a standard option for managing gynaecomastia risk, water retention, and other hormonal symptoms. Users report that it is typically administered alongside anabolic steroid cycles where elevated oestrogen levels are a concern.
