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.
If you start to notice side effects, such as the beginning stages of gynecomastia, excessive water retention, or high blood pressure despite using anti-estrogen medications to prevent them, then your Deca Durabolin dosage is likely too high for your body. Just as you titrated your dose upward, begin to titrate back down if you notice these bothersome side effects. As an example, if you were taking four 100mg doses per week, use four 75mg doses per week, instead. This will shave 100mg per week off of your overall dose, and you should notice a difference. If not, go down to three 75mg doses per week.
