Metridrol
Metribolone 2000iu
🧬 Anabolic Androgenic Steroid (AAS) | Non-aromatizable
💉 Sterile Injectable Solution
Description
Metribolone (also known as R-1881 or Methyltrienolone) is one of the most potent synthetic androgen receptor agonists ever developed. It exhibits extreme anabolic activity with no estrogenic conversion, making it suitable for short-term strength enhancement and hardening cycles.
🧪 Form and Storage
– 💉 Form: Sterile oil-based solution in multi-dose vial
– 🧊 Storage: Store at room temperature (15–25°C), away from light
– 🕒 Stability: Stable for up to 12 months unopened
– ⚠️ Do not refrigerate or freeze
– 🔁 Multi-use vial with sterile handling
🔬 What is Metribolone?
Metribolone is a 17α-alkylated derivative of trenbolone, exhibiting extreme affinity for androgen receptors in muscle and CNS tissue. It is non-aromatizing, non-reductive, and resistant to metabolic breakdown, making it highly active even in microgram doses. Originally studied for prostate cancer, its use remains limited to experimental and performance-enhancing contexts due to hepatotoxicity.
✅ Benefits of Metribolone
● Ultra-potent anabolic activity at microgram levels
● Zero estrogenic activity — no water retention or gynecomastia
● Dramatic increases in strength and aggression
● Enhances muscle density and vascularity
● No conversion to DHT or estrogen
● Ideal for contest prep or aggressive recomp protocols
⚠️ Possible Side Effects
● Severe hepatotoxicity — due to 17α-alkylation
● Suppression of endogenous testosterone
● Androgenic side effects: acne, hair loss, aggression
● No human-approved medical use — research only
● High toxicity profile — short-term use only
📏 Dosage Guidelines
● Research dosage: 250–500 mcg/day
● Cycle duration: 7–14 days maximum
● Route: Intramuscular (IM) or Subcutaneous (SC)
● Example: 250 mcg/day IM x 10 days for strength-phase stacking
🧼 Best Practices
● Use sterile technique for each injection
● Monitor liver enzymes and cholesterol levels closely
● Avoid concurrent hepatotoxic agents (e.g., oral AAS, alcohol)
● Only suitable for advanced users or research protocols
🧠 Lifestyle and Dietary Considerations
● Support with liver protectants: NAC, TUDCA, milk thistle
● Consume high-quality protein (2.2g/kg bodyweight)
● Ensure zero alcohol intake during cycle
● Prioritize cardiovascular health and HDL/LDL balance
