What Is Deus Medical Mastermed P 100?
Deus Medical Mastermed P 100 is an injectable anabolic compound containing Drostanolone Propionate at a concentration of 100mg/ml. Drostanolone Propionate is a short-ester derivative of dihydrotestosterone (DHT) that has been used in clinical and athletic settings for decades. Each vial is manufactured by Deus Medical, a well-known brand in the research and performance enhancement community, and is supplied in a 10ml multi-dose vial.
Because the propionate ester is short-acting, Mastermed P 100 is typically administered more frequently than longer-ester products. This gives users greater control over blood levels and allows the compound to clear the system relatively quickly. If you are researching Deus Medical Mastermed P 100, this guide covers its profile, key features, typical use cases and answers to common questions.

How Drostanolone Propionate Works
Drostanolone Propionate is a DHT-derived compound that does not aromatise into oestrogen. This means it is unlikely to cause oestrogen-related side effects such as water retention or gynaecomastia. Instead, it is often used in cutting phases where a lean, hard appearance is the goal. The propionate ester allows the compound to become active quickly and to be cleared from the body within a few days, making it easier to manage than longer esters like enanthate.
For those comparing options, the shorter half-life of Mastermed P 100 means more frequent injections but greater flexibility. Many users stack it with other compounds, and you can explore related research products in our advanced synergy stack if you are building a more comprehensive protocol.
Benefits and Common Use Cases
Drostanolone Propionate is most commonly associated with the following goals:
- Cutting and definition: Helps preserve lean muscle while in a calorie deficit.
- Hardening effect: Often used in the final weeks before a competition or photo shoot.
- Strength support: Can contribute to maintained or increased strength during dieting phases.
- Stacking: Frequently combined with testosterone or other short-ester compounds.
Because it does not convert to oestrogen, Mastermed P 100 is often chosen by individuals who are sensitive to oestrogenic side effects. However, it is important to note that all anabolic steroids carry risks and should only be used under appropriate supervision. For general information on these compounds, see the Wikipedia entry on drostanolone propionate.
