Of concern to any user of Winstrol during a cycle should be its intoxicating effect on the liver . The drug is a 17aa structured steroid , meaning it has been structured in a way which allows it to be orally bio-available, yet this has the negative effect of making Winstrol potentially harmful to the liver. It is therefore paramount the duration of a Winstrol cycle is limited, the dose of the drug is not excessive, the user does not stack it with other hepatotoxic compounds, does not drink alcohol whilst on cycle, and does not use Winstrol if they have an underlying medical condition which effects the livers health. There are supplements available which also help protect the liver (Milk Thistle, Liv-52 etc), and these would be advisable during any Winstrol cycle .
As an additional piece of information, Stanozolol is an alkylated compound. What that means is that it is designed to be able to go through your liver once without being destroyed or altered. Practically, that is one of the reasons that this drug can either be taken orally or injected. But, also because of that alkalization, it can be extremely damaging to your liver over time, and in that regard it is one of the worst of the steroid types for you to overuse. Another peculiarity of this specific compound is that people have found that the injectable form actually promotes greater nitrogen retention as opposed to the oral form.
