As with Proviron, another DHT derived oral steroid, Winstrol may be useful in any cycle (perhaps even bulking) in order to lower Sex Hormone Binding Globulin.(2) One of the properties of Winstrol is its profound ability to lower SHBG much more than other steroids. This could make more testosterone (or whatever steroids you are using) more likely to remain unbound and therefore active.
A nice quality look can be attained with the use of Winstrol in a decent cutting cycle, but having it in a heavy bulking cycle could end up being problematic, as people often get sore joints from using it for extended periods of time. Stanozolol is an alkylated compound, which means that its been specifically altered to endure the first pass through the liver without being destroyed. And since the injectable version is simply a suspended version of the same compound, its able to be orally ingested instead of injected. However, since it is alkylated, it is also pretty liver toxic, having one of the worst hepatoxicity (mg for mg) of any steroid. As regards cholesterol, and its quite harsh on both LDL and HDL (3), and cardiac hypertrophy could be a possible concern with Winstrol also. (4) Needless to say, most men dont use Winstrol for very long in their cycles, and limit it to about 6 weeks or so at 50-100mgs every day (and yes, the same dosing applies for the injectable or the oral). Women typically use 10-25mgs per day, with the high end of that being reserved for competitive bodybuilders and figure competitors. Of course, acne, hairloss and (in women) clitoral hypertrophy are very real concerns.
