Sterile Water for Injection is a pharmaceutical-grade water that is free from any microorganisms, pyrogens (fever-causing agents), and added substances. It is widely used in hospitals, clinics, and laboratories as a diluent or solvent for preparing injectable medications.

Overview

• Generic Name: Sterile Water for Injection
• Form: Clear, colorless, odorless liquid
• Composition: 100% purified water, sterilized
• Packaging: Available in glass ampoules, vials, or plastic containers (usually 5 mL to 1000 mL)

Description

Sterile Water for Injection is prepared by distillation or reverse osmosis and then sterilized to remove any bacteria or other contaminants. It does not contain any antimicrobial agents or added buffers, so once opened, it should be used immediately and discarded after a single use to maintain sterility.

Uses

1. Diluent for Injectable Drugs:
   Used to reconstitute or dissolve powdered medications (e.g., antibiotics, hormones, vaccines) before administration.
2. Solvent for Parenteral Solutions:
   Acts as a vehicle for preparing sterile solutions for injection.
3. Irrigation or Rinsing (in some cases):
   May be used for rinsing surgical instruments or wound cleaning when sterile conditions are required.

Administration

• Route: Intravenous (IV), Intramuscular (IM), or Subcutaneous (SC) — only after drug reconstitution.
• Not for direct injection unless specifically prescribed, as injecting plain sterile water intravenously can cause hemolysis (destruction of red blood cells) due to its hypotonic nature.

Precautions

• Use only under medical supervision.
• Do not use if the solution appears cloudy or contains particles.
• Discard unused portion after opening.
• Store at controlled room temperature, away from contamination.

Storage

• Temperature: 20°C to 25°C (68°F to 77°F)
• Keep sealed until use to maintain sterility.

Overview

• Generic Name: Drostanolone Propionate
• Strength: 100 mg per 1 mL
• Dosage Form: Injectable solution
• Active Ingredient: Drostanolone Propionate
• Base Compound: Dihydrotestosterone (DHT) derivative
• Route of Administration: Intramuscular (IM) injection

Description

Drostanolone Propionate is a synthetic anabolic steroid with moderate anabolic and low androgenic activity. The propionate ester allows the compound to be slowly released from the injection site, maintaining stable blood levels for several days.

It is typically formulated in an oil-based solution (such as sesame or cottonseed oil) to facilitate sustained release.

Medical Uses

Originally developed for medical purposes, particularly in the treatment of breast cancer in women, Drostanolone Propionate works by inhibiting estrogen activity and reducing estrogen-dependent tissue growth.

Today, its therapeutic applications include:

• Treatment of breast carcinoma (historically, now rarely used for this purpose)
• Adjunct therapy to promote muscle retention in specific medical conditions (under supervision)

Pharmacological Profile

• Chemical class: Androgenic anabolic steroid (AAS)
• Half-life: Approximately 2–3 days
• Onset of action: Rapid (within hours after IM injection)
• Duration: Short to moderate (requires frequent dosing for stable levels)

Key Effects

• Promotes lean muscle mass development (without significant water retention)
• Enhances muscle hardness and definition
• Does not aromatize to estrogen, minimizing risks of estrogen-related side effects such as gynecomastia or bloating
• May increase strength and improve muscle tone

Side Effects

As with all anabolic steroids, Drostanolone Propionate carries potential adverse effects, including:

• Hormonal imbalance (testosterone suppression)
• Acne and oily skin
• Hair loss (in those genetically predisposed to baldness)
• Increased aggression or mood changes
• Altered lipid profile (decrease in HDL, increase in LDL cholesterol)
• Liver stress (mild, as it is not orally active)
• Virilization in women (deep voice, facial hair, menstrual irregularities)

Precautions

• Use only under medical supervision.
• Not recommended for individuals with heart, liver, or kidney disease.
• Regular monitoring of lipid levels and liver function is advisable during treatment.
• Misuse for bodybuilding or athletic enhancement is illegal in many countries.

Storage

• Store at controlled room temperature (20–25°C).
• Protect from light and moisture.
• Do not freeze.
• Keep out of reach of children.

Important Note

Drostanolone Propionate (often known by the brand name Masteron) is a controlled substance in many regions and should only be used with a valid prescription for legitimate medical purposes.
