Arimidex tends to be the more popular aromatase inhibitor among anabolic steroid users, Aromasin tends to be the more superior aromatase inhibitor due to its properties and effects. This is due to two reasons: the first being that, as mentioned already, it is not as well known by virtue of the fact that Arimidex happened to be the aromatase inhibitor that hit the anabolic steroid using community first (and unfortunately Aromasin (Exemestane) was consequently overlooked), and secondly, Aromasin tends to be more expensive than Arimidex.
With that being said, Aromasin dosages for the purpose of Estrogen control on-cycle have proven to be far more effective than Arimidex both in terms of its ability to act as a suicidal inhibitor of the aromatase enzyme, as well as the fact that Aromasin is far more compatible.
It must first be understood that Aromasin is an extremely effective and very potent aromatase inhibitor, with a wide variety of application in terms of Estrogen control. As an aromatase inhibitor, it holds the ability to exert control over literally all of the potential Estrogenic side effects that anabolic steroid users attempt to avoid or eliminate.
As with most/all ancillary compounds, Aromasin cannot be categorized into the three tiers of users (beginner, intermediate, and advanced) as normally outlined and listed in common profiles of the different compounds and drugs. This is due to the fact that Aromasin is an ancillary drug not particularly used for the purpose of performance enhancement, but instead is utilized to combat or mitigate various Estrogen-related side effects when aromatizable anabolic steroids are utilized.
Aromasin holds several different capabilities of use aside from its Estrogen blocking capabilities, and not only is its Estrogen blocking capabilities a step above the other major aromatase inhibitors, but its ability to increase Testosterone levels is as well. This will be covered in greater detail very shortly, under Aromasin’s use during PCT.
In a performance setting, standard Aromasin doses will normally be 12.5-25mg every other day. Most should be fine with 12.5mg every other day, with some getting by with only two to three doses per week. The individual’s total sensitivity and the composition of the steroid in cycle in question will dictate the final outcome. There will be, however, some who require a daily dose with as much as 25mg per day. This should be short lived and only continued as long as necessary due to the possible cholesterol issues. This type of use can prove very useful for the competitive bodybuilder 7-14 days leading up to the completion in an effort to come in as dry and hard as possible. But again, this full dose use is only used for a limited time.
There is one issue with the addition of the other two aromatase inhibitors (Arimidex and Letrozole) in a PCT program that includes the use of SERMs such as Nolvadex and Clomid, which are known as absolutely essential components to a PCT program. The problem here is that Arimidex and Nolvadex both directly counteract one another. One study has demonstrated that when Arimidex is utilized with Nolvadex, Nolvadex will decrease blood plasma concentration of Arimidex (as well as Letrozole, another commonly used aromatase inhibitor). The conclusion here is that the use of Arimidex or Letrozole with Nolvadex together is a very bad idea and may work counter productively if used together in a PCT protocol.
Aromasin completely circumvents this problem, as it has been demonstrated to have no interactions what so ever with Nolvadex, unlike the other two aforementioned aromatase inhibitors. In one study, Aromasin displayed no reduced effectiveness, nor any reduced blood plasma levels when utilized with Nolvadex. Nolvadex is also very well known for reducing blood plasma levels of IGF-1 during use. This might possibly indicate that Aromasin may assist to maintain stable IGF-1 levels or at the very least do nothing to further worsen Nolvadex’s effects on IGF-1. Therefore, from all of the information gathered, Aromasin and Nolvadex when utilized together for PCT are very complimentary with one another, making Aromasin the absolute best aromatase inhibitor not only for general use but also for HPTA recovery during PCT (or at any other time).
A sufficient Aromasin dosage for HPTA recovery during PCT would be 25mg daily for no longer than a 2 week period while Nolvadex would be utilized for a total of 4 weeks at 20 – 40mg daily.
There are no special considerations with administration of Aromasin doses, and it can be taken at any time of the day (morning, night time, before, during, or after meals). Prescription guidelines and pharmacy information have demonstrated that Aromasin’s absorption and bioavailability might be increased when taken with or after a meal (preferably a high fat content meal).
One important note to make with Aromasin is that a full week (7 days) is required before blood plasma levels of Aromasin have reached its optimal peak level, although its half-life is approximately 27 hours
