When a man uses anabolic androgenic steroids (AAS), certain compounds will aromatize into estrogen. The main culprits that will do this are all testosterone esters, such as: cypionate, enanthate, dianabol, deca durabolin, and less so Boldenone (EQ). If estrogen isn’t inhibited by using an AI (aromatase inhibitor), then high-estrogen side effects can occur. The most well-known side effect is gynecomastia or what is known commonly as ‘gyno’, ‘bitch tits’ or ‘man breasts’. A man may notice a lump forming within his breast(s) – or under the nipple area; if not treated quickly, this can require serious surgery to remove. The lesser known but very serious side effects are caused by water retention, which can give a bloated or ‘full’ look. Extra water weight to your body or face (commonly called “moon face for its round or full look) can ruin a nice physique by making a person look fat. Internally, carrying around extra water weight will strain the body’s lipids across the board. A person can expect a rise in blood pressure, heart strain, and loss in energy. Also, high estrogen can affect libido.



Dosages of arimidex will vary from person to person. This is why blood work is essential to finding the perfect balance. One should start out at half a mg every other day and adjust as needed for the cycle. Some AAS users will not use an AI at first but they will have it on hand just in case. This isn’t always a good idea, as once you start noticing gyno or excessive water weight it could be too late to reverse. Since AAS will continue building in the body and aromatize (steroids turning into estrogen), taking arimidex at this point would be like trying to stop a car already in motion.



General dosages for men: 0.5mgs per day or every other day. Remember, it’s steroid dose dependent.
