Masteron (Drostanolone Propionate)
Masteron is a European injectable preparation containing the steroid drostanolone propionate. Drostanolone is a derivative of dihydrotestosterone, most specifically 2alpha-methyldihydrotestosterone. As a result, the structure of this steroid is that of a moderate anabolic/potent androgen which does not aromatize to estrogen. Water retention and gynecomastia are therefore not a concern with this compound; as of course here estrogen is usually the culprit. Masteron may in fact exhibit antiestrogenic activity in the body, competing with other substrates for binding to aromatase. This would reduce the conversion rate of other steroids, Masteron acting in the same manner as the oral steroid Proviron®.
Bodybuilders have a strong appreciation for non-aromatizing androgens, and find Masteron very useful as a cutting agent. It is likewise generally used a number of weeks prior to a competition, in an effort to bring out an improved look of density and hardness to the muscles. For this purpose Masteron should work exceptionally well so long as the body fat percentage is low enough. Provided everything fits as if should, the user can achieve that “ripped” look so popular to professional bodybuilding. The androgenic effect can also be crucial during this period, a time when caloric intake is drastically lowered. The user is provided added “kick” or “drive” to push through the grueling training sessions leading up to the show. Drostanoione was once also popular with athletes subject to drug testing, as for a period of time this compound was not screened for during competition. The urinary metabolites of drostanoione were recognized by the early 90’s however, and this drug now adjoins a long list of anabolic/androgenic steroids identifiable during urinalysis testing. Although some bodybuilders claim they can safely use Masteron if discontinued three to four weeks before a test, there are always uncertainties with the use of esterified injectable steroids. This perhaps makes the oral DHT Proviron® (1-ethyldihydrotestosterone) a slightly better choice, as orals offer much better control.
The standard Masteron dose for adult men will normally fall in the 300-400mg per week range. Normally, this will mean an injection of 100mg every other day for a total of 6-8 weeks. This does not mean 6-8 weeks represents the total cycle, but this is a common time frame for the Masteron portion of a stack. Some may alternatively choose to split their dose up into a daily injection schedule, but every other day should suffice. If a Drostanolone Enanthate version is found, 1-2 injections per week will work, but such a version is somewhat rare. For female breast cancer treatment, standard dosing calls for 100mg three times per weeks for 8-12 weeks. This will commonly lead to virilization symptoms that could be hard to reverse. However, no one can deny it’s still better than cancer.
For the female athlete, 50mg per week should be more than enough for a total of 4-6 weeks. Some women may find doses closer to 100mg per week to be justified if they tolerate the hormone well. Doses of this range should be controllable for most women, but individual sensitivity must be kept in mind. Doses that go above the 100mg per week mark or beyond 4-6 weeks of use will more than likely produce virilization symptoms at some level.
Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Drostanolone should have a stronger negative effect on the hepatic management of cholesterol than testosterone or nandrolone due to its non-aromatizable nature, but a weaker impact than c-17 alpha alkylated steroids. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.
