Cardiovascular risk factors include the alteration or diminishing of her glucose tolerance and hyperinsulinism (become resistant to insulin), a change in lipoproteins (carry cholesterol in blood) fraction which can cause cardiovascular disease and atherosclerosis (deposition of fatty substances onto inner walls of arteries causing blockage), increased triglyceride levels, hypertension (abnormally high blood pressure), changes in her myocardium (middle muscular layer of heart wall), and increased concentration levels of several different clotting factors. Cardiomyopathy (a typically chronic disorder of heart muscle that may involve hypertrophy and obstructive damage to the heart), myocardial infarction (localized death of the myocardium tissue usually leading to heart failure), heart attack, stroke, and cerebro-vascular accidents have all been causes in deaths where AAS abuse was implicated. Of course the liver, the body’s primary filtration system will come under attack as it has to accommodate the increased toxicity. Among the liver problems promoted are holestatic jaundice (failure of bile flow that causes yellowish pigmentation of skin, tissues, and body fluids), peliosis hepatis (blood-filled cysts develop on liver), hepatocellular hyperplasia (unusual increase of an epithelial parenchymatous cell called hepatocytes in the liver), and cancer. Secondary filters such as the kidneys and gallbladder also become more susceptible to disease.
The cycle length of Masteron cycles are usually in the range of 8 – 10 weeks, mostly due to its short-ester nature. Some bodybuilders will elect to utilize Masteron only within the final 2 – 4 weeks of a cycle leading up into a show or a photoshoot, only to gain advantage of its physique enhancement abilities. This generally looks like a cycle performed for 10 weeks, with compounds such as Testosterone Propionate, Trenbolone Acetate, and Anavar being used. Towards the 6 or 8-week mark of said cycle, Masteron would be included into the mix (alongside perhaps a removal of one of the other compounds), and run right to the end of the 10th week.
The pharmacodynamic variability in plasma testosterone and inhibin concentrations is accounted for by the variability between esters and the site and volume of injection of the nandrolone injections. The overall kinetics of suppression of testosterone is dominated by the slow negative feedback system, rather than the much faster metabolic clearance of testosterone. This negative feedback is mediated via inhibition of pulsatile gonadotropin-releasing hormone secretion from hypothalamic neurons into the pituitary portal system and then pituitary LH secretion from gonadotropes. This is in stark contrast to a highly potent and specific gonadotropin-releasing hormone antagonist that causes immediate cessation of gonadotropin-releasing hormone action leading to castrate testosterone concentrations within 12 hr, compared with 5 to 10 days with AAS administration. After a single 100 mg injection of NPP, recovery takes 10+ days. After ND, recovery takes 15+ days. It is important to note these are single administrations of 100 mg. HPTA recovery with repeated doses of 200+ mg is long!!!! (3, 8)
