What is Superdrol (Methasterone)?

Superdrol (Methasterone — injectable potent DHT-derived anabolic-androgenic steroid) is methasterone — C₂₁H₃₄O₂, MW 318.5 — formulated as an oil-based injectable at 50mg/mL. 2α,17α-dimethyl DHT derivative with exceptionally high anabolic activity and moderate androgenic activity. Does not aromatise to oestrogen. Originally released as a prohormone (2005); reclassified as a controlled AAS. Injectable format provides direct systemic delivery without first-pass hepatic metabolism.

Research Applications

High-Potency DHT-Derived Anabolic Research

Methasterone’s exceptionally high anabolic/androgenic ratio compared to testosterone and nandrolone

Non-Aromatising AAS Model

Potent anabolism without oestrogen co-effects — pure AR-mediated signalling research

Injectable vs Oral AAS Comparison

Oil-based injectable methasterone vs oral — first-pass metabolism elimination studies

Muscle Protein Synthesis

High-potency anabolic effects — nitrogen retention and protein synthesis kinetics

Prohormone/Designer AAS Pharmacology

Regulatory history and receptor pharmacology of methasterone as a designer steroid

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.
Peptide Research Tools: Use Vesta’s free peptide calculators — reconstitution, BAC water, dosing, half-life, and mixing charts.
