HCG within the medical field is primarily administered via intramuscular (IM) injections, although it can also be administered subcutaneously, which has also become just as frequent as IM injections. Studies have found that when intramuscular and subcutaneous injections of HCG were compared, the results were almost the exact same for both, indicating almost no difference between the two  . The only difference between the two methods of injection is the difference in the rate of release from the injection site and the time required for peak blood plasma levels to be reached (6 hours for IM, and 16 – 20 hours for subcutaneous). The majority of anabolic steroid users will elect to inject HCG subcutaneously.
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 .
