is what we call an aromatase inhibitor (AI). In clinical use, it´s used to halt the progression of Breast Cancer in women. It works by blocking the aromatase enzyme, which is responsible for the production of estrogen. In athletics and bodybuilding, it is used as an ancillary compound to be added to a cycle of Anabolic Steroids. In this respect it is also used for its estrogen reducing properties, but it has the additional benefit of increasing testosterone levels, as we´ll see... Arimidex Side EffectsMany anabolic steroids aromatize (convert to estrogen via the aromatase enzyme), and this is responsible for many of the unwanted side effects found with anabolic steroid use (acne, gynocomastia, water-retention, etc...). In one study, both .5mg and 1mg doses of Arimidex were shown to decrease estrogen by roughly 50%. The 1mg/day dose also increased testosterone levels by 58% (1). In that same study, in both groups, LH and FSH also went up slightly.          More.......

is one of those weird compounds that nobody really knows what to do with. What we generally hear about it makes it very uninteresting…It’s a third generation Aromatase Inhibitor (AI) just like Arimidex (Anastrozole) and Femera (Letrozole). Both of those two drugs are very efficient at stopping the conversion of androgens into estrogen, and since we have them, why bother with Aromasin? It’s a little harder to get than the other two commonly used aromatase inhibitors, because it’s not in high demand, and there’s never been a readily apparent advantage to using it. And I mean…lets face it: It’s awkward-sounding. Aromasin doesn’t have much of a ring to it, and exemestane is even worse. Arimidex has a bunch of cool abbreviations ("A-dex" or just ‘dex) and even Letrozoleis just "Letro" to most people. Where’s the cool nickname for Aromasin/exemestane? A-Sin? E-Stane? It just doesn’t work. It’s the black sheep of AIs. And why do we even need it when we have Letrozole, which is by far the most efficient AI for stopping aromatization (the process by which your body converts testosterone into estrogen)? Letro can reduce estrogen levels by 98% or greater; clinically a dose as low as 100mcgs has been shown to provide maximum aromatase inhibition (2)! So why would we need any other AIs? Well, first of all, estrogen is necessary for healthy joints (3) as well as a healthy immune system (4). So getting rid of 98% of the estrogen in your body for an extended period of time may not be the best of ideas. This may be useful on an extreme cutting cycle, leading up to a bodybuilding contest, or if you are particularly prone to gyno, but certainly can’t be used safely for extended periods of time without compromising your joints and immune system.          More.....

Arimidex is an aromatase inhibitor (sometimes called an AI). It is usually provided in 1MG tabs or in liquid form. The drug works in a non-steroid form by inhibiting the aromatase enzyme which convertstestosterone and other androgens into estrogen. This means that there is less estrogen tocause female pattern fat deposits, gyno, and water retention. In medicine, Arimidex isutilized to treat prostate cancer. In sports chemistry, the drug has been employed as ameans of preventing excessive estrogenic side effects.         More......   

is the aromatase inhibitor of choice. The drug is appropriately used when using substantial amounts of aromatizing steroids, or when one is prone to gynecomastia and using moderate amounts of such steroids. Arimidex) does not have the side effects of aminoglutethimide (Cytadren) and can achieve a high degree of estrogen blockade, much moreso than Cytadren. It is possible to reduce estrogen too much with Arimidex, and for this reason blood tests, or less preferably salivary tests, should be taken after the first week of use to determine if the dosing is correct.          More.......

Masteron is, to be honest, my favorite Anabolic/Androgenic Steroid (AAS). For many years, this compound was unavailable to the average athlete; it was frequently counterfeited, often very expensive, and almost never available on the black market. The most common form of this product, as manufactured by major pharmaceutical houses, is 50mg/ml ampules with either 1-2mls per amp (or vial). Needless to say, these products used to be the only game in town, and since this drug was a particularly sought-after compound for bodybuilding contest preparation, it´s price made it prohibitive for all but the highest level bodybuilders. Masteron is a derivative of DHT (as you can tell from its chemical name: 2a-methyl-dihydro-testosterone propionate), but what they fail to tell you is that DHT and its derivatives are commonly used in treatment of certain forms of breast cancer (see the etymology here: MASTectomy, gynocoMASTia, MASTeron, get it?). Masteron is not clinically used for weight gain (as is common with most steroids), so this makes it a very unique steroid from that perspective. Unfortunately, much of the information on Masteron available in medical journals doesn´t focus on weight or strength gain or even fat loss, for those reasons.   More.....

Ok. I’ll admit it. I didn’t know much about anti-estrogens and their ilk before I started researching this article. And I’ll admit another thing: I didn’t care. I knew that 10mgs of Nolvadex per day was all I ever needed to not get gyno, though 50 mgs/day of Clomid seemed to work the same for me. Cytadren (remember that stuff?) worked for me also, at 250mgs/day, but it seemed to make me more prone to joint problems. HCG worked best for me when I shot 500i.u. every other day post cycle for about 3 weeks. Arimidex was too expensive. AND THAT’S ALL I NEEDED TO KNOW!          More......

Now onto Femara (AKA Letrozol), which is more effective than Arimidex in it's ability to pass thru the cell membrane of lipid (fat) cells and inhibit the activity of aromatase -- Arimidex is just over 80% effective at inhibiting aromatase, Femara is around 95-97%. Other than that, both of these drugs stop the process of aromatization, rather than just blocking the receptors as Clomid and Nolvadex do. An effective dose of Letrozole is 1-2.5 mg/day, but be forewarned, it can kill your sex drive, and could decrease IGF levels. On the other hand, I’ve seen studies where it increases IGF levels         More......
