Product name: Anastrozole
Alias: Arimidex
CAS No: 120511-73-1
MF: C17H19N5
MW: 293.37
Appearance: white crystalline powder
Usage: Arimidex with its ability to block the synthesis of estrogen can alleviate some of these embarrassing and obvious side effects of anabolic steroids. Plus, it has been observed that the 1mg dose of Arimidex can also increase the levels of testosterone. In the past, most body builders used drugs like Nolvadex or Proviron against the excess estrogen, but many prefer Arimidex because its actions are rapid and effective. Individuals who use Arimidex for this purpose suggest a starting dose of 0.25 mg/day. Only if no response is seen after a few months, should the dose be increased to 0.5-1.0 mg. The great thing about Arimidex is that it can be used with a variety of anabolic steroids.
Half-Life: The half-life of arimidex is around 46 hours, so it tends to build up in your system when used daily.
What is Arimidex ?
it is a non-steroidal aromatase inhibiting drug (acronym AI) and is approved for treatment of breast cancer after surgery and for metastasis in women. Since breast cancer can be heightened by the increase in estrogen, arimidex is used to inhibit the synthesis of estrogen.
Almost 10,000 women with localized breast cancer from all over the world ran a trial of Arimidex, Tamoxifen (which also reduces estrogen but as a SERM, not an AI), alone or in combination. A Selective Estrogen Receptor Modulator (SERM), like Tamoxifen (Nolvadex), binds with estrogen receptors, blocking some estrogen actions while at the same time allowing others.
Arimidex & Bodybuilding
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.
On the other hand, if you are too aggressive in inhibiting estrogen, by using compounds that are harsher than Arimidex, this can cause your estrogen to drop too low. As a result, you can expect erectile disfunction (ED), loss of energy, depression and low libido.
Arimidex vs Nolvadex
The main advantage of using doxorubicin over SERM, such as tamoxifen (nolvadex), is arimidex blocking aromatase; thus preventing the first generation of estrogen. As a comparison, tamoxifen will prevent estrogen receptors from receiving estrogen rather than stopping production sources. So when you use SERM, you will still float estrogen in your body.
Arimidex vs Letrozole
Arimidex's side effects are not so harsh compared to other side effects of letrozole. The most common is erectile dysfunction. Although estrogen is called estrogen, but men still need to be in the body. For men, estrogen can balance hormones and help them gain muscle and strength. That's why it comes to letrozox, a serious AI kill almost all estrogen, and is not always the best in your cycle to achieve hormone balance. On the other hand, it is arimidex glowing place because it is a mild AI and will not crush your estrogen levels so you can be more balanced.
Arimidex Alternatives
Letrozone is about the only realistic alternative OTC aromatase inhibitor on the market, it contains formestane, which is a powerful AI. While arimidex is prescription only, you can buy letrozone OTC without a script.
Arimidex Dosages
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.
