Masteroxyl 100




Masteroxyl 100 from Kalpa Pharmaceuticals, with the main active substance Drostanolone Propionate, is a special anabolic steroid based on the method of obtaining this drug from dihydrotestosterone (DHT). It has a high androgenic activity, but has a small anabolic effect.

This drug is very common in bodybuilding, it is used to give muscles rigidity and shape and is also used as an aromatase inhibitor. Athletes often use this drug at the end of a steroid cycle. Masteroxyl should always be combined with other steroids so that it can fully perform its work and demonstrate the best results. It is especially effective to combine it with aromatizing preparations such as Dianoxyl and testosterone esters (Testoxyl Cypionate, Testoxyl Enanthate). It will not retain water in the body, and will also be an aromatase inhibitor.

Our customers choose Masteroxyl 100 for being one of the strongest antiestrogenic anabolic steroids. This drug not only does not have estrogenic properties, but also acts as an antiestrogen in the body.

Due to the fact that Drostanolone Propionate gives muscles the necessary shape, stiffness, has a fat-burning effect, and helps you to fight against the accumulation of excess water in the body, this drug is often used during preparation to competitions.


Beginners can take the recommended weekly dose of just 200-300 mg. However, advanced users believe that the best dosage for them would be 400-500 mg per week. It is combined with such drugs as Dianoxyl, Testosterone, Stanoxyl, Oxandroxyl, Boldaxyl and Trenboxyl.
