What is Metribolone (Methyltrienolone)?

Metribolone (Methyltrienolone — ultra-potent non-aromatising synthetic androgen research compound) is methyltrienolone — C₁₉H₂₄O₂, MW 284.4 — at a low-concentration 5mg/mL formulation reflecting its extreme potency. 17α-methyl-trenbolone derivative considered one of the most potent androgens ever synthesised. ~120× greater AR binding affinity than testosterone. Does not aromatise. Used as the gold-standard AR reference ligand in receptor binding assays. Extreme potency necessitates very low concentrations for research use.

Research Applications

Gold-Standard AR Binding Reference

~120× greater AR affinity than testosterone — standard reference for AR competition binding assays

Ultra-Potent Androgen Pharmacology

Ceiling AR agonist for maximum AR activation dose-response curve determination

Non-Aromatising Androgen Model

Potent pure androgenic signalling without any oestrogenic co-effects

Progesterone Receptor Research

High PR binding affinity — progestogenic activity alongside extreme AR potency

Comparative Anabolic-Androgenic Research

Reference standard for relative binding affinity comparisons of other AAS

Frequently Asked Questions

How is this Vesta injectable supplied?
Vesta injectable solutions are supplied ready-to-use — no reconstitution required. Each vial contains the stated concentration in pharmaceutical-grade carrier (oil or aqueous). Draw using a sterile syringe appropriate for the solution viscosity.
How should this Vesta injectable be stored?
Oil-based solutions: store at room temperature (15–25°C), away from direct sunlight — do not refrigerate as cold temperatures can cause crystallisation. Aqueous solutions: store at 2–8°C. Properly stored, injectable solutions are stable for 2–3 years.
What purity is this Vesta injectable and how is it verified?
All Vesta injectable compounds are ≥99% pure by HPLC on every production batch, with MS-confirmed identity. COA is published on the product page and independently verifiable at verify.janoshik.com.
