Masteron (Drostanolone Propionate) is an original form of Masteron. This steroid is an incomparable anti-estrogenic anabolic steroid. For the first time it was developed in the name of Mastril to treat the breast cancer. It was extensively used for the selective estrogen receptor modulator. Tamoxifen to significantly decrease the estrogen level in women suffering from the disease. Therefore, because of these effects, it is mostly used by many athletes and the bodybuilders.

This therapeutic steroid was successfully running in the market for almost two decades for the treatment of breast cancer and it further become famous among bodybuilders for the cutting steroid. It is now no longer present and has been discontinued by the manufacturer. However, it is still famous among the bodybuilders to offer competitive bodybuilding cycles and is essential for the preparation of contest.


Particularly, two types of Masteron are available to use that is Drostanolone Propionate and Drostanolone Enanthate. Where Propionate is dosed at 50 to 150 mg/ml and Enanthate is dosed at 200mg/ml to be injected twice a week because the ester attached to it is longer and resulting in slower release of hormone.

    People, what is your opinion in this case? If by chance anyone has used, I would like to know your point of view, dose and timing used. Can you also highlight some good stacks to use along with Masteron? I was thinking to go ahead with Deca, test and Masteron cycle.

      You will get an amazing synergy with Test/Masteron, as the later is not only helpful in hardening up but also ends estrogen effect. Deca/Test/Masteron is a perfect cycle if you are not prone to gyno! Through progesterone, Deca releases its negative impact. So, I would recommend rather invest in cabergoline to be on a safer side. Many users do not use Masteron at right dose which should be at least 500mg/wk and will comment it is good only when you are using 10%bf. Masteron is most likely as Winny, which is a DHT derivative. However, the major concern with Winny is that it can make you feel week in the knees causing joints pain. Moreover, increase in strength is not much pronounced as Winny!

        You can try this cycle for better results:
      • 12 Weeks
      • 500mg Masteron
      • 500mg Test E
      • 600mg EQ
      Where EQ, IMHO work together in synergy with the two compounds. However, if you are looking forward for the overall weight gain then I would recommend Deca, if you are not prone to gyno.

      Precisely, which one it is Enathate or Propionate? I have been using both often. Here I would like to suggest you to add Testosterone Enathate and Testosterone Propionate whichever you have. Dosage will rely on your experience and size but begin with, you can start:

      • Test Prop = 100-150mg every other day
      • Dros Prop = 100mg every other day
      • or
      • Test Enan = 200-300mg twice a week (like Monday and Thursday)
      • Dros Enan = 200mg twice a week
      We can be of more help, if you will tell us your goal and purpose of using the drug and you can determine it by your cycle and what for you are using it.
