This is an oral steroid and so it puts strain on the liver, for this reason it is recommended https://jbhnews.com/winstrol-cycle-and-results/30767/ by many to never use over 50mg a day and take for longer than 6 weeks, there are users who take much higher dosages for longer periods of time, but this is not a good idea. If you use winstrol a dosage of 50mg is more than enough for good results, if you want better results then stack it with other steroids.
