Description
Methyltrenbolone 1 mg Astera Labs — Methyltrienolone (Metribolone, M3) — oral trenbolone analogue with extreme AR affinity. Research-grade dosing in micrograms. Each unit dosed at 1 mg.
Key Benefits
- Metribolone / M3 — extreme AR affinity, research-grade only
- Effective at micrograms, not milligrams — dosing precision critical
- No aromatisation, no progestagenic activity
- Extreme hepatotoxicity — short blocks, strict bloodwork
- Not a real-world protocol compound — almost exclusively research use
- Each unit dosed at 1 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: 500–2000 mcg/day for 1–3 weeks. Yes — micrograms. Effective at 1 mg/day for most research purposes. Dosing precision matters — a 2× error on metribolone is a 2× error on one of the most potent AAS ever synthesised.
How It Works
17α-methyl trenbolone — the oral analogue of tren. Extreme AR affinity (~40× testosterone) via both the trenbolone core and the 17α-methyl group that resists first-pass metabolism. No aromatisation. Used primarily in AR-binding research; real-world use is vanishingly rare due to toxicity.
Pharmacokinetics
Plasma half-life approximately 6 hours. Split daily dose 2×. Hepatotoxicity extreme — liver enzyme elevation within days of dosing. Short cycle length is the only safety mechanism.
Potential Side Effects
Hepatic damage rapid and dose-dependent. Lipid collapse. HPTA suppression severe. Aggression and mood lability intense. Not a beginner, intermediate, or typical-advanced compound — essentially a research tool.
Cycle & Stacking Guide
Research / extreme-research context only. 1–3 week blocks at mcg doses. If used, aggressive liver support + bloodwork before, during, and post. Modern protocols substitute standard trenbolone injectable or oxymetholone for lower-risk alternatives.
Manufacturer Notes
Astera Labs produces a broad catalogue from research peptides to AAS oils. Lyophilised peptide vials ship with stability documentation.
Storage & Handling
Store upright at 15–25 °C in the original box, protected from light and moisture. Oil-based injectables are shelf-stable for the duration printed on the vial when kept at controlled room temperature. Do not refrigerate — cold thickens the carrier oil and makes drawing/injecting harder. Keep out of reach of children. For research and educational purposes only.
