Enantoro 250 ™ is a highly anabolic and androgenic hormone; it has an anabolic (muscle building) as well as anabolic rating of 100 each, respectively. Enantoro 250 ™ exerts the majority of its effects by promoting increased nitrogen retention in the muscle. Enantoro 250 ™ is also known to increases levels of the growth factor IGF-1 in both the muscle tissue as well as the liver. Enantoro 250 ™ also increases the activity of satellite cells, which are cells that play an active role in repairing exercise-damaged muscle. Enantoro 250 ™ exerts these effects primarily by genomic mechanisms, meaning that it binds to the androgen receptor thus initiating gene transcription. This stimulation of the AR promotes various of the AR dependant mechanisms for both muscle gain and fat loss, as well as reducing catabolic glucocorticoid hormones, and increasing red blood cell production. Enantoro 250 ™ may even aid in protecting the heart against coronary disease. Enantoro 250 ™ binds to the AR on fat cells resulting in fat breakdown and also prevents new fat formation. Unfortunately, there is also a down side to testosterone as well. Testosterone is metabolized in the body to the female hormone estrogen (via aromatization) by the aromatize enzyme. This can lead to some unwanted and nasty side effects; breast tissue growth in men (gynocomastia), some fat gain and even reduced fat breakdown, testicular shrinkage and water retention which can increase blood pressure. Testosterone is also a substrate for the 5alpha-reductase enzyme. Interaction with this enzyme converts the testosterone to Dihydrotestosterone (DHT), a more androgenic form of the parent hormone, though a less anabolic one. DHT has a high binding affinity to the tissues of the scalp and prostate, resulting in hair loss in loss and making the prostate swell.
