Stanozolol, commonly sold under the name Winstrol (oral) and Winstrol Depot (intra-muscular), was developed by Winthrop Laboratories in 1962. It is a synthetic anabolic steroid derived from testosterone, and has been approved by the FDA for human use.
Unlike most injectable anabolic steroids, Stanozolol is not esterified and is sold as an aqueous suspension, or in oral tablet form. Both forms contain the exact same compound, but injecting this compound (and yes, you can drink the injectable version, and no you shouldn´t) is superior to ingesting it orally in terms of nitrogen retention and thus one would also imagine, for overall anabolism. Injecting it also has the advantage of avoiding the "first pass" through your liver, and thus places your liver under less stress. The drug has a large oral bioavailability, due to a C17 α-alkylation which allows the hormone to survive first pass liver metabolism when ingested. It is because of this that Stanozolol is also sold in tablet form.
Stanozolol is a cutting drug. Not many people will argue for its use in a bulking cycle. It´s certainly not a very effective compound for treating anemia 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. One of the properties of Winstrol is it´s 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, it´s 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). As with running virtually any compound, testosterone supplementation (i.e. running test in a cycle containing Winstrol) is warranted to avoid possible sexual dysfunction.
Stanozolol is also one of the few compounds that women can take safely, as it´s anabolic:androgenic ratio is quite skewed towards anabolism. It´s generally accepted that women can tolerate around 5-10mgs a day of this compound. Men, on the other hand can dose themselves in the .5-1.5mg/kg range. A cycle with Winstrol/Parabolan/Testosterone would prove more beneficial for most bodybuilders seeking to get ripped.
Although the anabolic ratio of this product is very high as compared to its androgenic actions, not many people report huge weight gains off of Stanozolol. Also, interestingly, it has a relatively weak AR binding ability, which is quite unusual for a "cutting" steroid. Many of the effects of this drug, as relates to building muscle, are probably from its very high protein synthesizing ability. In addition, since this compound is derived from DHT, it tends to promote a very nice, "quality" look to the user´s muscles, with little or no water retention. Winstrol does not aromatize at any rate and has even been speculated to have anti-progestenic properties (in at least some cases, where it may "block" that receptor). If one were to run ancillary compounds with Stanozolol, perhaps Tamoxifen(Nolvadex, Tadex) would be appropriate for it´s beneficial effects on blood lipids, but an anti-estrogen (in it´s classic sense) would be unwarranted; proper post cycle therapy is still needed, though.
