Characteristics ;
Maston is available in oral form. However it is non-alkylated, which makes it NOT toxic to the liver. It is also available in injectable form as Propionate and Enanthate esters.

As Masteron does not aromatize it doesn’t converts to estrogen.

Masteron is a derivative of DHT which makes it strongly androgenic. This provides a strong and durable musculature.However, it does not develop much muscle mass.

That’s why it is mainly used during fat loss cycles, often stacked with other steroids with similar property such as Winstrol or Primobolan for example. Such combinations to accentuate its effects, are very effective to get a skinned and hard look.It is good to know that Masteron does not reduce body fat ; your diet and your food supplements must hence be in adecuation.

In order to improve the muscular quality, with no water retention either, one can find it better to stack it with other mass building products like Testosterone or any Testosteron-like steroid.

propionate ester, a short ester, will slow the release of Drostanolone for only 2 to 3 days.

Enanthate,  called a long ester, will release the hormone for about 10 to 14 days.

Masteron binds up to 5 times greater to a testosterone receptor tan Testosterone itself.
This means that it can hang out longer. The result is an increased AAS activity. The affinity of Masteron makes it also compete for the aromatase receptor. This leads Masteron to act as an anti-estrogen.
The ability to inhibit the enzyme at its own receptor and to still act as a powerful non-aromatizing AAS is quite unusual.

An example of an excellent 8 weeks cutting cycle would be:

150mg Testosterone propionate every other day
50mg Trenbolone acetate every day (or 100mg every other day)
150mg Masteron (propionate) every other day
50mg Winstrol every day, last 4 weeks of cycle only

With such an advanced cycle, one could also incorporate for instance Clenbuterol, Ephedrine, T3, growth hormone, IGF, etc.
Side effects ;
Masteron is a relatively safe medicine, even at high dosages. This is definitely not a reason to use excessive doses however. As for other AAS, extra dosages do not give any more benefit than a biological optimum. For Masteron, let’s say that injections above 600mg per week are just a waste of money.
