Drostanolone propionate is primarily used in the medical field to treat advanced breast cancer cases in postmenopausal women. Also, it is used to treat anemia, osteoporosis, and other medical conditions. It works by blocking the effects of estrogen, which can help slow cancer cell progression. In addition, drostanolone propionate can help to reduce the risk of bone fractures in patients with osteoporosis. It can also help improve red blood cell production in anemia patients.

Drostanolone propionate, also known as dromostanolone propionate, is a synthetic androgenic anabolic steroid. Its primary mechanism of action involves binding to androgen receptors in the body. Here are the key points:

Androgen Receptor Binding: Drostanolone propionate binds to androgen receptors, which leads to genetic transcriptional changes. This interaction promotes the retention of nitrogen, potassium, and phosphorus12.
Protein Synthesis: The binding to androgen receptors stimulates protein synthesis and nitrogen retention, which enhances muscle growth and repair34.
Antitumor Activity: It has been used in the treatment of certain types of breast cancer due to its ability to reduce or competitively inhibit prolactin receptors or estrogen receptors1.
Anabolic Effects: The drug increases protein anabolism (the building of proteins) and decreases amino acid catabolism (the breakdown of proteins), which contributes to muscle growth1.
Performance Enhancement: Due to its anabolic properties, drostanolone propionate is popular among athletes and bodybuilders for its ability to enhance physical performance, particularly during cutting cycles.

Contraindications

Hypersensitivity to drostanolone or any component of the formulation.

Men with carcinomas of the breast or with known or suspected carcinomas of the prostate; women who are or may become pregnant.

Documentation of allergenic cross-reactivity for androgens is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.

Warnings/Precautions

• Hepatic effects: Prolonged use and/or high doses may cause peliosis hepatis or liver cell tumors, which may not be apparent until liver failure or intra-abdominal hemorrhage develops. Discontinue in case of cholestatic hepatitis with jaundice or abnormal liver function tests.
• Venous thromboembolism: Venous thromboembolic events, including deep vein thrombosis (DVT) and pulmonary embolism (PE), have been reported with testosterone products. Evaluate patients with symptoms of pain, edema, warmth, and erythema in the lower extremity for DVT and those with acute shortness of breath for PE. Discontinue therapy if a venous thromboembolism is suspected.

Here are some key points about its drug interactions:

Drug-Drug Interactions:
Anticoagulants: Drostanolone propionate may enhance the effects of anticoagulants, increasing the risk of bleeding1.
Insulin and Oral Hypoglycemic Agents: It can affect blood glucose levels, potentially requiring adjustments in the dosage of insulin or oral hypoglycemic agents1.
Other Steroids: Combining with other anabolic steroids can increase the risk of adverse effects such as liver toxicity and cardiovascular issues1.
Drug-Food Interactions:
There are no significant food interactions reported, but maintaining a balanced diet is recommended to support overall health and mitigate potential side effects2.
Drug-Condition Interactions:
Prostate Cancer: Drostanolone propionate is contraindicated in patients with prostate cancer due to its androgenic effects1.
Cardiovascular Disease: It can exacerbate conditions like hypertension and increase the risk of cardiovascular events.

Drostanolone propionate, also known as Masteron, is an anabolic steroid with several potential side effects and adverse reactions. Here are some of the key ones:

Common Side Effects
Masculinization: This includes symptoms like acne, increased hair growth, voice changes, and increased sexual desire1.
Cardiovascular Effects: There is a potential for negative cardiovascular effects, such as increased risk of heart disease2.
Hormonal Imbalances: This can include testosterone suppression and other hormonal disruptions2.
Psychological Effects: Users may experience mood swings, aggression, and other psychological changes2.
Less Common but Serious Side Effects
Fluid Retention: This can lead to swelling in various parts of the body3.
Hypercalcemia: Elevated calcium levels in the blood, which can be dangerous3.
Liver Toxicity: Although less common, prolonged use can lead to liver damage2.
It’s important to consult with a healthcare provider before using drostanolone propionate to fully understand the risks and ensure it’s appropriate for your situation.

Drostanolone propionate, commonly known as Masteron, is an anabolic steroid primarily used in bodybuilding for its muscle-hardening effects. However, it is not recommended for use during pregnancy or breastfeeding. Here are some key points:

Pregnancy
Safety: Drostanolone propionate has not been proven safe for use during pregnancy1.
Risks: Using anabolic steroids during pregnancy can potentially harm the developing fetus, leading to congenital disabilities and other complications.
Breastfeeding
Safety: The safety of drostanolone propionate during breastfeeding has not been established1.
Risks: Anabolic steroids can pass into breast milk and may affect the nursing infant, potentially causing adverse effects.
General Precautions
Consultation: Always consult with a healthcare provider before using any medication, especially during pregnancy and breastfeeding.
Alternatives: If you require treatment for a condition that drostanolone propionate addresses, your healthcare provider can suggest safer alternatives.

Store in a cool dry place between 15-25°C. Protect from light.

Drostanolone propionate 100mg should be stored in a cool, dry place, away from direct sunlight and out of reach of children. This helps maintain its stability and effectiveness.
