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.
Testosterone Enanthate is an extremely popular anabolic steroid, and should be found very easily on the anabolic steroid black market without any effort. It is also so common and easily manufactured that it should be obtained for very reasonable prices. Testosterone Enanthate exists as both human-grade pharmaceutical grade products, as well as underground lab (UGL) grade products on the market. The differences are obvious here, with quality control being the main issue, and that pharmaceutical grade Testosterone Enanthate is usually more expensive for obvious reasons.
