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 (7), 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 (6) (8). 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) (9). If one were to run ancillary compounds with Stanozolol, perhaps Tamoxifen 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.
