Trenbolone is a synthetic anabolic androgenic steroid that belongs to the 19-nortestorone family. It was initially created for use in the veterinary field to increase growth and muscle bulk in animals. Trenbolone steroid is used in the form of prodrugs that are in the form of esters. So far, there are three types of Trenbolone esters that are available in the market. These include Trenbolone Acetate, Trenbolone Enanthate and Trenbolone Hexahydrobenzylcarbonate.
Once the drugs are digested, they are activated and increase the uptake of ammonium ions by muscles and this increases the rate of protein synthesis in the body. There is increased catabolism as a result of increased lipolysis. Fat is broken down to provide the body with energy. Trenbolone steroids have been shown to increase the expression of androgen receptors on cells. This makes Trenbolone a very potent steroid.
Trenbolone has an added effect of promoting the action of the insulin like growth factor 1, IGF-1. IGF-1 is responsible for increasing growth in almost all cells including muscles, the brain, ligaments and tendons. It also has catabolic activity on fat tissue. It has affinity for glucocorticoid receptors and progesterone receptors.
Another action is to lead to increased red cell production. Trenbolone steroid acts on the kidneys to make them produce the erythropoietin hormone. Erythropoietin increases the bone marrow production of red blood cells. Red blood cells are the blood cells responsible for oxygen carrying and delivery to the tissues. This is quite necessary when the steroid use is combined with intense exercises. With the muscular hypertrophy that develops, the muscles need more oxygen delivery in order to recover faster. The muscle strength is also increased.
Trenbolone is used in the form of prodrugs and esters so as to increase the half life. An increase in the half life means that, longer dosing schedules are possible. The esters once in the blood stream are cleaved by lipases to give freely circulating Trenbolone.
Trenbolone is mostly used during the cutting phase of a steroid cycle. During the cutting phase, the aim is to maintain lean body tissue while reducing the levels of fat through diet. Trenbolone preserves lean muscle during this phase as normally lean muscle is broken down to provide energy, with Trenbolone however, fat is used as a substrate for energy production instead. Trenbolone facilitates fat metabolism by binding to androgen receptors in adipose tissue and leading to lipolysis. Trenbolone can also be used during the bulking season has this steroid is very potent in muscle increase.
Despite the many pleasant effects of Trenbolone steroid, it also has side effects. Some of the side effects depend on the individual, their age, their exercise routines and what they use for Trenbolone stacking. Some of the androgenic side effects include development of gynecomastia, reduction in testicular size and low levels of testosterone. The anabolic side effects include the worrisome adverse effects on the cardiovascular system including the risk of cardiomyopathy, heart attack and hypertension. Another anabolic side effect is liver toxicity.
