1. Description — Clinical summary
Masteron Propionate Zycare 100 mg/mL is an injectable preparation of drostanolone propionate presented in a convenient 10x1ml ampoule format. Drostanolone is a dihydrotestosterone (DHT) derivative originally developed for the treatment of breast cancer in postmenopausal women. The Zycare ampoule format provides single-use sterile dosing, eliminating multi-dose vial contamination concerns.
Key points:
- Active compound: drostanolone propionate, oil-based intramuscular injection in pre-sealed ampoules.
- Concentration: 100 mg per mL, 10 ampoules per box (1000 mg total per box).
- Presentation advantage: single-use ampoules ensure sterility and accurate dosing per injection.
- Drostanolone is a 2α-methylated DHT derivative that does not aromatize to estrogen.
2. How does drostanolone propionate work?
Mechanism of action — pharmacology summary:
- DHT derivative: Drostanolone is structurally related to dihydrotestosterone with a 2α-methyl modification that increases its anabolic activity and resistance to 3α-hydroxysteroid dehydrogenase metabolism.
- Anti-estrogenic properties: Acts as a mild aromatase inhibitor, reducing estrogen conversion. This contributes to the hardening and drying effects on physique.
- Non-aromatizing: Does not convert to estrogen, eliminating estrogen-related side effects such as water retention and gynecomastia from the compound itself.
- Androgenic activity: Moderate androgenic effects. The propionate ester provides a relatively short half-life of 2-3 days, requiring frequent administration.
- Protein synthesis: Enhances nitrogen retention and protein synthesis, supporting lean muscle preservation particularly during caloric deficit.
3. Dosage — usage guidelines
Important: Drostanolone is not widely approved for current medical use. Historical medical dosing was for breast cancer treatment. Information below is for clinical reference.
A. Historical medical use:
- Breast cancer (postmenopausal women): 100 mg three times weekly by intramuscular injection.
B. Reported non-medical use patterns (informational only):
- Typical reported patterns: 100mg (1 ampoule) administered every other day due to the propionate ester half-life.
- Cycle length: commonly 8-12 weeks.
- Frequently combined with testosterone and other compounds during cutting phases.
- The ampoule format simplifies dosing at 100 mg per injection.
4. Side effects — common and rare adverse effects
A. Common adverse effects:
- Androgenic effects: acne, oily skin, accelerated male pattern hair loss in genetically predisposed individuals.
- HPG axis suppression: suppression of endogenous testosterone production.
- Cardiovascular: adverse lipid profile changes (decreased HDL, increased LDL).
- Injection-site reactions: pain, swelling at injection site.
B. Serious/rare effects:
- Virilization in women: deepening of voice, hirsutism, clitoromegaly (may be irreversible).
- Cardiovascular complications with chronic use: hypertension, left ventricular hypertrophy.
- Hepatic: generally considered low hepatotoxicity (non-17α-alkylated).
C. Monitoring:
- CBC with hematocrit, lipid panel, liver function tests.
- Blood pressure monitoring, serum testosterone, LH, FSH.
5. Storage
- Store at controlled room temperature: 20-25°C (68-77°F). Brief excursions permitted between 15-30°C.
- Protect from light: keep ampoules in original packaging.
- Do not freeze oil-based injectable formulations.
- Ampoules are single-use: discard any remaining solution after opening. Do not store opened ampoules.
- Inspect ampoules before use: do not use if cracked, discolored, or containing particulates.
- Use single-use sterile needles and syringes. Never share injection equipment.
- Dispose of used ampoules and sharps per local regulations.
