Measurements of levels of 17α-OHP are useful in the evaluation of patients with suspected congenital adrenal hyperplasia as the typical enzymes that are defective, namely 21-hydroxylase and 11β-hydroxylase , lead to a build-up of 17α-OHP. In contrast, the rare patient with 17α-hydroxylase deficiency will have very low or undetectable levels of 17α-OHP. 17α-OHP levels can also be used to measure contribution of progestational activity of the corpus luteum during pregnancy as progesterone but not 17α-OHP is also contributed by the placenta .
Anabolic steroids differ in their characteristics, which means there are steroids that are only suitable for specific uses. For instance, Trenbolone is not recommended for bulking but it is an outstanding fat burner. This makes it perfect for a lean mass cycle or a cutting cycle. Always take the side effects of a particular compound into consideration whenever you plan a stack. Do not combine anabolic steroids that show similar side effects. For example, never combine Anapolon and Dianabol because they are already quite toxic and if you combine them, the toxicity will increase exponentially and cause serious damage to your body.
Trigonella foenum-graecum, more commonly known as fenugreek, has been purported to inhibit aromatase and 5-α reductase. A clinical trial did in fact show that fenugreek did inhibit aromatase and 5-α reductase to a certain extent, and it increased endogenous testosterone levels. It also resulted in greater increase of fat loss, increase of fat free mass, and one-repetition-maximum values for the leg press than those who did not take fenugreek. Another clinical trial resulted in an increase in bench press one-repetition-maximum for those who were supplemented with fenugreek. Fenusterols is a fenugreek seed extract that contains 50% steroidal saponins.
