Winstrol is generally not preferred for building mass as it is highly anabolic and very slightly androgenic, an oral Steroid such as Dianabol is usually a better choice for people wanting to bulk up. Due to its ability to dramatically lower SHBG it can be used in a bulking cycle as a means to make other hormones more efficient, increase free testosterone and even solidify gains to a stronger degree but most of the people will find other steroids to be far more beneficial than winstrol in the long run. However some people are very sensitive to side effects of certain Steroids such as Dianabol, and would rather use Winstrol in a bulking cycle, while the weight gain wont be as dramatic as with Dianabol, with a proper high calorie diet, you can still see good results.
The average Trenbolone Acetate dose varies based on your cycle and stack. During an off-season bulking cycle, most bodybuilders find that 50mg every other day is comfortable and effective. Some men tolerate up to 100mg every other day with no issues, and they find that this does offers the best results for them. During a cutting cycle, people tend to push the envelope a little more with Tren and utilize doses even higher than 100mg every other day, but not everyone can tolerate these as the risk of side effects increases. No one should ever use more than 200mg every other day, even if they seem to tolerate it well.
