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 .
Winstrol is hepatotoxic, and because of this, it should be used at the lowest effective dose for the shortest possible cycle. What’s more, you should consider using a supplement designed to provide some additional protection. Milk thistle is a highly recommended option; studies suggest it can provide an effective layer of protection when it is used for the entire length of your cycle. There are some other supplements on the market, such as Liver Care, which are blends of natural ingredients that have been shown to work together to prevent liver toxicity.
Although Winstrol does possess a weaker androgenic strength rating than Testosterone does, androgenic side effects are still a potential risk, though much lower, and may only effect users significantly if they are especially sensitive to androgens. Androgenic side effects can include increased oily skin and acne, hair growth on the body, MPB (male pattern baldness), and BPH (Benign Prostatic Hypertrophy). The use of a 5-alpha reductase (5AR) inhibitor, such as Finasteride, Dutasteride, Proscar, or Propecia will be completely ineffective here, as Winstrol does not convert into DHT.
