Masteron is a derivative of DHT , and DHT and its derivatives are commonly used in treatment of some forms of breast cancer. Sadly, much of the information on Masteron available in medical journals does not focus on weight or strength gain or even fat loss. It wont aromatize and it wont have progesteronic sides, remember, Nolvadex as most ancillaries are used to reduce estrogen for breast cancer patients, so a drug used to treat breast cancer clearly would not convert to estrogen and Masteron may interact with the aromatase enzymes to hinder aromatization of other steroids into estrogen.

Furthermore it may interact with estrogen as a blocker at the receptor site. This is how it’s used to fight breast cancer. This could also be part of the cause for Masteron being considered a cutting and or a Pre-contest and hardening steroid. Masteron may actually be extremely useful for combating estrogenic/progesteronic side effects. If Masteron is included into your cycle, you may not need other ancillaries. Much like Proviron, Masteron could be used as an anti side-effect drug. Along the same line, being a DHT derivative, it has a very good ability to add muscle hardness to an already lean athlete. Masteron has a misleadingly low anabolic to androgenic ratio, since DHT is five times as androgenic as Testosterone and has a three to four times higher likeness to receptor sites, it provides a lot of results for the price when examined on a mg for mg basis.
Masteron is a stronger androgen than it appears on paper, and due to this fact, can cause amplified aggression. Higher androgens also produce that hard look valued by competitive body builders, and androgens also promote fat loss. The effects of Masteron, in that way are consistent with the documented effects of other androgens to decrease lipoprotein lipase and up regulate -adrenergic receptors on adipocytes, which would inhibit the accumulation of fat and enhance the efflux of fat from these cells in response to catecholamine’s. Basically it helps eliminate fat as well if not better than much higher scored androgens, partially due to its derivative of DHT. This reduction in fat and rise in aggression could be helpful for people competing, or who are on a condensed caloric diet.

Being a DHT derivative means that it can have certain undesirable sides as well such as acne, hair loss, prostate enlargement, etc. The maximum therapeutic dose is pretty high: 167mgs per day, every day of the week, for a 220lb person...and that is not considered excessive by the FDA who has not been conventionally open-minded on dosing protocols meaning clearly, up to that dose is pretty much safe for almost anyone.

Stacking Masteron: your best bet is with test, of course but really, due to Masterons good binding to the Androgen Receptors and its high androgenic properties, almost any cutting drug such as anavar or tren could be included in a cycle with it for an proficient stack. You have to inject Masteron Every Other Day at least 100mgs EOD at the lowest dose you might as well stack it with Test Prop, or Winstrol, and Eq is another well-liked choice to stack with Masteron.
Optimum effects of Masteron, utilizing Euro-Pharmacies line are found with 400 to 500mgs per week, for maximum cost effectiveness. It is also important to spread shots out on an EOD basis, as the Masteron Propionate is required more frequently due to its short ester.
