What Is Evo Pharma Masteron P 120mg?
Evo Pharma Masteron P 120mg is marketed as an injectable preparation containing drostanolone propionate, commonly referred to as Masteron Propionate or Masteron P.
General product details:
- Compound: Drostanolone Propionate
- Common Name: Masteron Propionate (Masteron P)
- Strength: 120mg/mL
- Administration: Intramuscular injection

The propionate ester provides a relatively short duration of action compared with longer esters such as drostanolone enanthate.
What Is Drostanolone Propionate?
Drostanolone propionate is a synthetic anabolic-androgenic steroid derived from dihydrotestosterone (DHT).
Its characteristics include:
- DHT-derived anabolic steroid
- Injectable administration
- Short-acting propionate ester
- Does not significantly aromatize into estrogen
Historically, it was approved for treating certain types of breast cancer, although it is no longer widely used for this purpose.
How Does Masteron P Work?
Drostanolone binds to androgen receptors throughout the body.
Its biological activity may influence:
- Protein synthesis
- Nitrogen retention
- Muscle tissue maintenance
- Development of male secondary sexual characteristics
- Hormonal signaling
Like other anabolic steroids, exogenous drostanolone may suppress the body’s natural testosterone production.
Medical Background
Drostanolone propionate was historically prescribed for certain forms of breast cancer because of its anti-estrogenic properties. Today, it has largely been replaced by newer treatment options and is rarely prescribed in routine medical practice.
Masteron P in Fitness and Bodybuilding Discussions
Within bodybuilding communities, Masteron Propionate is frequently discussed in relation to:
- Lean muscle appearance
- Muscle hardness
- Increased muscle definition
- Improved vascular appearance
- Strength improvements
These uses are outside approved medical indications and may involve significant health risks. Anecdotal reports should not be considered medical evidence.
Hormonal Effects
Drostanolone may suppress the body’s natural hormone production.
Potential hormonal effects include:
- Reduced natural testosterone production
- Lower luteinizing hormone (LH)
- Lower follicle-stimulating hormone (FSH)
- Reduced sperm production
- Temporary fertility changes
- Hormonal imbalance
Recovery varies depending on the individual and duration of exposure.
Estrogen Considerations
Drostanolone is a DHT-derived steroid and does not significantly aromatize into estrogen.
Because of this, estrogen-related effects such as:
- Water retention
- Gynecomastia directly caused by aromatization
are generally less common than with aromatizing anabolic steroids.
Cardiovascular Considerations
Like other anabolic-androgenic steroids, drostanolone may influence cardiovascular risk factors.
Potential concerns include:
- Reduced HDL (“good”) cholesterol
- Increased LDL (“bad”) cholesterol
- Elevated blood pressure
- Increased cardiovascular strain
Healthcare professionals may recommend monitoring:
- Blood pressure
- Lipid profile
- Complete blood count
Possible Side Effects
Potential side effects associated with drostanolone propionate may include:
- Acne
- Oily skin
- Hair loss in genetically susceptible individuals
- Mood changes
- Increased body hair
- Hormonal suppression
Women exposed to drostanolone may experience androgenic effects such as:
- Voice deepening
- Increased facial or body hair
- Menstrual irregularities
- Clitoral enlargement
Some androgenic effects may be irreversible.
Injection-Related Considerations
Injectable anabolic steroid products may involve:
- Injection-site pain
- Redness
- Swelling
- Infection if sterile technique is not followed
- Local irritation
Proper sterile injection practices are important to reduce these risks.
Product Quality Considerations
Products obtained outside regulated pharmaceutical systems may vary in:
- Active ingredient concentration
- Sterility
- Purity
- Manufacturing consistency
- Batch quality
Potential concerns include:
- Counterfeit products
- Incorrect labeling
- Contamination
- Variable potency
Independent laboratory analysis may help verify product quality where available.
Storage Recommendations
Injectable products should generally be stored:
- At controlled room temperature
- Away from direct sunlight
- Protected from excessive heat
- In the original packaging
- Out of reach of children
Do not use if:
- The vial is damaged
- The solution appears cloudy or contains unexpected particles
- The product has expired
