Masteron

Chemical Name: Drostanolone (Propionate)
Drug Class: Injectable Anabolic Steroid


Masteron has recently become very popular on the underground market, and with good reason. It gained a cult following in the 80’s when it was available pretty widely, but then gained even more of a cult following when it was pulled from the market. As with most other steroids (Trenbolone comes to mind), when it becomes unavailable, it also becomes highly desirable. And for the better part of two decades, it was virtually unavailable to the average athlete; except for the times when it was counterfeited. Back then, this stuff was available in is 50mg/ml ampules with either 1-2mls per amp (or 2ml vial). Back then, even when it was reasonably available, it was unreasonably expensive. Still, expensive or not, it may be the most effective injectable steroid in the world to use in a cutting cycle. Only Trenbolone comes close, but the possible side effects with Tren (Tren-cough, sexual dysfunction, etc..) make Tren a distant second in my book.

Masteron is a derivative of Dihydrotestosterone (DHT) with an added 2a-methyl group. As with any DHT derivative, it is structurally incapable of conversion to estrogen and progesterone. Masteron is unique as it is one of the rare anabolic steroids that is not clinically used for weight gain. It’s never used for treatment of anemia or wasting diseases like Cancer or AIDS. Masteron is clinically treating certain forms of breast cancer (1)(2), at which it is reasonably effective. It has, however, been largely replaced by third generation Aromatase Inhibitors such as Arimidex and Aromasin. However, in at least one study, Masteron & Tamoxifen outperformed than Chemotherapy with regards to producing immediate objective responses from patients (3). It’s actually a weak anti-estrogen, and that’s where a lot of its “hardening” properties probably come from, and why it’s so useful in precontest cycles. If you aren’t using a lot of aromatizable drugs (and are using them in low doses), then Masteron may actually be the only anti-estrogen you need.
Masteron may actually interact with the aromatase enzyme to inhibit aromatization (conversion/metabolism) of other steroids into estrogen. Additionally, Masteron seems to be able to interact with estrogen at the receptor site. (1)(2)

On a personal level, I really like Masteron. I have found it to be a more potent androgen than it appears on paper. The relatively low anabolic and androgenic ratings that it has don’t really do it justice. Androgens of this type seem to be able to produce the hard quality look prized by competitive Bodybuilders. They also promote lipolysis (fat loss), and aggression.

Masteron stacks well with testosterone, and typically I like to stack it with something with a similar ester length. One of my favorite cycles included Masteron, Nandrolone (Phenylpropionate), and of course Testosterone Propionate. Trenbolone and Equipoise are popular additions to cycles including Masteron, as is Testosterone (always a must) and Anavar. Sometimes Winstrol is used instead of Anavar, to keep costs down.


The minimum dose with Masteron is typically 100mgs/EOD (Every Other Day), with a maximum of 600mgs per week being used. I’ve found my own ideal dose to be in the middle, at about 500mgs/week. Unfortunately, all good things come at a cost, and Masteron is no different. On average, it’s going to run between $50-$75 per 10 ml bottle, at a typical concentration of 100mgs/ml.
