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 .
Being c17alfa-alkylated anabolic, Stanozolol tablets can be hepatotoxic for you liver so do not use oral Stanozolol for more than 6-8 week, or better prefer the injectable form to pills. Negative effect of Winnie V on the level of cholesterol is also declared. So you should check out the level of cholesterol from time to time on a regular basis. Winny V as almost all anabolic steroids, inhibits your own natural testosterone production. Acne, hair loss, prostate enlargement and virilization are other side effects. As it has been already said, to avoid undesirable side effects the time and the dosage of using should be strictly supervised.
