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.
HCG within the medical field is primarily administered via intramuscular (IM) injections, although it can also be administered subcutaneously, which has also become just as frequent as IM injections. Studies have found that when intramuscular and subcutaneous injections of HCG were compared, the results were almost the exact same for both, indicating almost no difference between the two  . The only difference between the two methods of injection is the difference in the rate of release from the injection site and the time required for peak blood plasma levels to be reached (6 hours for IM, and 16 – 20 hours for subcutaneous). The majority of anabolic steroid users will elect to inject HCG subcutaneously.
Before you can understand why Trenbolone works the way it does, you first need to understand that you have two types of fat, or adipose tissue, in your body. First, you have visceral adipose tissue, which surrounds your organs and has very little effect on your overall appearance. Second, you have subcutaneous adipose tissue, which rests just below the skin and has a tremendous impact on your appearance. As Trenbolone binds to androgen receptors (which it does very well), it inhibits lipid uptake. This means that your body cannot continue to add to its subcutaneous fat stores. As such, when you work out, you burn away the subcutaneous adipose tissue and obtain the “cut” appearance. This is why Tren is widely regarded as the best steroid to lose weight.
