Arimidex (Anastrozole)


Arimidex (Anastrozole)




by  Alen Hao –Sales Manager of Raw steroid powder ,Email:alen@ok-biotech.com – Arimidex (anastrozole) was the first selective aromatase inhibitor used in bodybuilding, and is still the most popular estrogen control drug. It’s commonly available in both tablet and liquid form for oral use. Dosing is typically 0.25, 0.5, or 1.0 mg at a time, at a frequency of once per day or per two days.

Estradiol, the most potent form of estrogen, is produced in the body by aromatization of testosterone. This occurs via the aromatase enzyme. Because certain levels of estradiol are needed for men, some conversion of testosterone to estradiol is required. However, in two circumstances effective aromatase inhibition can give important benefits.

First, when an anabolic steroid cycle causes very aromatizable steroid levels and there is no control of the aromatase enzyme, conversion to estradiol becomes excessive. The resulting high estradiol can cause gynecomastia, water retention, depression, and/or loss of libido. It may also make it difficult to maintain a lean condition.

And second, some men have excessive estradiol levels even when not on an anabolic steroid cycle. This will act to decrease their natural testosterone production, and can also cause the above adverse side effects.

Arimidex is highly suitable for solving either problem. With correctly chosen dosing, free estradiol level can be brought fairly accurately to a desired range. When not using anabolic steroids, for most men I recommend about 20-29 pg/mL for best effect on mood, performance, libido, and long term health and to provide excellent benefit to natural testosterone production. During a steroid cycle, levels can be allowed to rise a little higher, because high androgen levels act towards countering adverse actions of estradiol. Sometimes levels are deliberately made higher, as being a little “wet” can improve lifting performance. Still, I recommend that even during a strong anabolic cycle, estradiol level be kept to no more than about 40 pg/mL.This will usually require an aromatase inhibitor such as Arimidex, if dosing of aromatizable steroids is high.

The most highly aromatizing steroids are testosterone, methyltestosterone, and Dianabol, but Deca (nandrolone) and Equipoise (boldenone) also aromatize.

Most medical studies of effect of Arimidex on men have used it at 1 mg/day, with this dosage appearing about optimal judging from effect on estradiol level. However, real world use for either steroid cycles or optimization of hormone levels is generally at a lower dosage, from 0.25 mg every other day to about 0.5 mg/day. I generally recommend 0.5 mg every other day as a starting point for a steroid cycle, and half that for hormone optimization if a high estrogen problem exists.

Overdosing of Arimidex leads to abnormally low estradiol level and typical side effects of joint pain, reduced libido, and/or gastrointestinal distress. The first two are directly caused by low estradiol. If experiencing these effects, reduce dose. Effect on the GI tract appears a side effect of Arimidex itself, but one which fortunately affects only a few. If experiencing this effect, I recommend switching to letrozole as an alternate choice of aromatase inibitor.

Anastrozole has a half life of about two days. For this reason, when use is ongoing, on taking a dose of Arimidex the user will have in his system not only the dose that he just took, but also about another two days’ worth that has built up in his system. If just starting usage, however, there is no such buildup and effect will be less.

Rather than waiting a couple of weeks for buildup to occur, I instead recommend frontloading Arimidex. This is done by taking as the first dose not only the regular amount, but also an additional two days’ worth. For example, if intending to take 0.5 mg every other day, then this would be an additional 0.5 mg. The frontloading dose would therefore be 1.0 mg. This would be taken only on the first day of use. With this method, the proper effect is achieved nearly immediately.

A controversial use of Arimidex is in PCT. Some advocate driving estradiol levels abnormally low in PCT in order to stimulate testosterone production; I’m a strong advocate of instead using a SERM such as Nolvadex or Clomid instead. However, if a person needs Arimidex even off-cycle due to his having naturally high aromatization, then his off-cycle dosage may be employed during PCT as well.

Arimidex is best compared with letrozole. Either drug can be used effectively for aromatase control. The choice between them can be made entirely on personal preference, experience, and availability.

Description:

All testosterone forms are the same in-terms of the active hormone; Testosterone Propionate, Testosterone Cypionate,Testosterone Enanthate or any other form you can think of are all comprised of the same identical testosterone hormone. Testosterone Propionate is therefore much faster acting than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule, in order to maintain stable blood levels. Testosterone propionate has been used for studying its effects on pregnant ewes.
The benefits of Testosterone Propionate are truly great and in short the benefits most anyone would desire to hold if anabolic steroids were being used. Through the use of Testosterone Propionate we aptly create a playing field perfect for almost any situation be it bulking, cutting or simply trying to provide an added athletic edge. Through its use the individual can expect to see increases in lean tissue and strength, decreased body fat due to improved metabolic function as well as a greater ability for healing and recovery.

Applications:

Testosterone Propionate is the shortest commonly ester attached to the Testosterone hormone. This means it takes your body the least amount of time to rid itself of the ester and release the parent hormone into the body. Due to its short active life, testosterone propionate typically needs to be injected every other day at a minimum. Anecdotally, testosterone propionate causes the least side effects and the least bloating; these side effects usually subside very quickly when use is ceased.
Testosterone propionate is therefore much faster acting than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule, in order to maintain stable blood levels. Can be used as pharmaceutical material. Its main function is to Promote metabolism. Anabolic effects include growth of muscle mass and strength, increased bone density and strength, and stimulation of linear growth and bone maturation.

Bulking, cutting, HRT or any other reason you can think of, Testosterone Propionate is a perfect choice to meet all your testosterone needs. Regardless of your purpose, because the half-life is so short necessarily you will need to inject this steroid every other day if it is going to be used in the most effective and efficient means possible; maintaining stable blood test levels is important and every other day administration is the only way this will be achieved with Testosterone Propionate. As for your Testosterone Propionate cycle, most will find 8 weeks of use to be the bear minimum with 16 weeks being far more efficient.

Testosterone propionate is relatively faster acting than other the testosterone esters such as cypionate or enathate injections and is known as the short-acting form of testosterone. Short-acting testosterone solutions like propionate are injected in a dosage of 25 mg to 50 mg IM, and many hormone treatment programs specify injecting 50mg to 200mg 2 to 3 times a week for a total of 200mg to 500mg.

Description

Winstrol - Stanozolol is a very commonly used anabolic steroid for cutting cycles. While many people will attempt to use Dianabol or even Anadrol for cutting cycles, Ive really never heard of anyone using Stanozolol for anything except a cutting cycle. Its a bit of a one-trick-pony in this respect. Let me repeat that: Stanozolol is a cutting drug. Not many people will argue for its use in a bulking cycle. Its certainly not a very effective compound for treating anemia (1) and thus, one could rightly assume that its role in bulking cycles is very limited. One novel use for Winstrol in any cycle (perhaps even bulking) would be to use it at a very limited dose, in order to lower SHBG. (2) One of the properties of Winstrol is its profound ability to lower SHBG much more than other steroids. A dose of .2mg/kg lowered SHBG significantly, which would in turn, raise the amount of free testosterone circulating in the body. As with 99% of steroids, however, its important to note that suppression of your natural hormonal levels will occur (though perhaps not to the extent that it will with many other steroids).(10) As with running virtually any compound, testosterone supplementation (i.e. running test in a cycle containing Winstrol) is warranted to avoid possible sexual dysfunction.



Applications:

The oral use of stanozolol can also have a profound impact on levels of SHBG (sex hormone-binding globulin). This is a characteristic of all anabolic/androgenic steroids, however its potency and form of administration make Winstrol particularly noteworthy in this regard. Since plasma binding proteins such as SHBG act to temporarily constrain steroid hormones from exerting activity, this effect would provide a greater percentage of free (unbound) steroid hormone in the body. This may amount to an effective mechanism in which stanozolol could increase the potency of a concurrently used steroid. To further this purpose one could also addition Proviron, which has an extremely high affinity for SHBG. This affinity may cause Proviron to displace other weaker substrates for SHBG (such as testosterone), another mechanism in which the free hormone level may be increased. Adding Winstrol and Proviron to your next testosterone cycle may therefore prove very useful,, markedly enhancing the free state of this potent muscle building androgen.

Healthy Deca Durabolin Nandrolone Decanoate powder Muscle Growth

Quick Detail:

1. CAS No: 360-70-3
2. Molecular Formula: C28H44O3 
3. Assay: 97.0%~103.0%
4. Appearance: White crystalline powder.
5. Usage:can be used as pharmaceutical material, used to treat anemia associated with chronic (long-term) kidney failure.



Description:

Nandrolone Decanoate
Alias: Deca-Durabolin;19-Nortestoterone decanoate
CAS No:  360-70-3
Einecs No: 206-639-3
MF: C28H44O3
MW: 428.65
Purity: 98%
Appearance: light white powder, odourless. Refrigeration preservation.
Refrigeration save:Room temperature more than 20 Celsius degree to agglomerate,or so 30 Celsius degree into a liquid.



Applications:

In earlier years, testosterone and nandrolone were the only pharmaceutical injectables that were both widely available to bodybuilders and economical. Estrogen control did not then exist. For this reason, Deca’s low aromatizing properties were then quite useful. Deca therefore won wide popularity.
Steroids Hormone Nandrolone Decanoate/Deca-Durabolin/19-Nortestoterone decanoate/DECA powders/CAS No: 360-70-3
Use after surgery for chronic wasting disease, serious illness, and weak thin, infirm, osteoporosis, infantile dysplasia, aplastic anemia, etc.
Deca Durabolin (nandrolone) is that this compound is relatively mild in terms of adverse side effects on the scalp and skin. This is because the 5-alpha reductase enzyme acts to reduce the potency of nandrolone, while in contrast many other anabolic steroids are unaffected by this enzyme, and testosterone’s potency is actually increased by it.
