Insulin has significant anabolic and anti-catabolic properties and impacts the metabolism of various macromolecules, not just that of carbohydrates. Trenbolone binds the androgen receptor with an affinity five times higher than that of testosterone and is popular for its fat-burning and anabolic properties. H. Trenbolone C18H2202 Insulin C257H383NosO77S6 How do the different targets, mechanisms of action and durations of each drug ultimately lead to the same desired effect (increase in lean body mass)?

The synthetic pathways for many steroid hormones are shown in Fig. 23-1 in Silverthorn. This Is shown in a simplified format below with several intermedlate steps omitted.
