The Oxandrolone hormone does not carry any estrogenic related side effects. It does not aromatize and cannot lead to gynecomastia or water retention due to increases in estrogen levels.

Some steroids that do not aromatize can lead to high blood pressure, such as Trenbolone , but Anavar is rarely associated with this trait.

The severe side effects of Clenbuterol include high blood pressure, irregular heartbeat, trembling and even panic. Some studies have also shown that Clenbuterol abuse can also lead to cardiac hypertrophy, which could potentially lead to death.
