The use of anabolic steroids such as Winstrol may be associated with serious adverse reactions, many of which are dose related. Patients should be placed on the lowest possible effective dose. Medications that may interact with Winstrol include anticoagulants (blood thinners), insulin , or an oral diabetes medicine. Tell your doctor all medications you are taking. Winstrol is known to cause birth defects in a fetus. Do not take this medication if you are pregnant or could become pregnant during treatment. It is not known whether Winstrol is excreted in human milk. Many drugs are excreted in human milk and there is the potential for adverse reactions in nursing infants from anabolic steroids. Consult your doctor before breastfeeding.
Since stanozolol is not capable of converting into estrogen, an anti-estrogen is not necessary when using this steroid, gynecomastia is not a concern even among the most sensitive individuals. Since estrogen is also the cause of water retention, instead of bulk look, Winstrol produces a lean, quality look with no fear of excess subcutaneous fluid retention. This makes it a great steroid to use during cutting cycles, when water and fat retention are a major concern. It is also very popular among athletes in combination strength/speed sports such as Track and Field.
