Superdrol Injectable — Methyldrostanolone 40mg/ml by Dragon Pharma
Superdrol Injectable is Dragon Pharma's injectable formulation of Methyldrostanolone at 40mg/ml in MCT oil — the same active compound as Superdrol 10mg tablets, administered via intramuscular injection to bypass the first-pass hepatic metabolism that drives oral Superdrol's severe hepatotoxicity. For the complete compound background — including the methylated Masteron structure, prohormone history and mechanism — see the oral Superdrol page.

Why Injectable — The Hepatotoxicity Reduction Rationale
Injectable Methyldrostanolone is unusual — 17-alpha-alkylated compounds are almost exclusively oral because the alkylation's primary purpose is oral bioavailability. The injectable format addresses the oral form's core limitation:
- When oral Superdrol is swallowed, 100% of the absorbed dose passes through the liver (first-pass metabolism) before reaching systemic circulation. The 17-alpha-methyl group protects the compound from hepatic breakdown — but this resistance also means the compound is fully present in liver tissue at high concentration during this first pass, driving the severe hepatotoxicity
- When Superdrol is injected intramuscularly, it enters the bloodstream directly — bypassing the first-pass hepatic exposure entirely. The compound still reaches the liver via systemic circulation, but at the systemic blood concentration rather than the concentrated first-pass dose
- The result: injectable Methyldrostanolone produces significantly lower liver enzyme elevation than the oral form at equivalent doses — though hepatotoxicity is not eliminated (the compound still passes through the liver systemically) — it is meaningfully reduced
- This reduction in first-pass hepatic load is the primary reason for the injectable format's existence — it allows Superdrol's anabolic effects to be used with a more manageable hepatic safety profile
Oral vs Injectable Superdrol — The Practical Comparison
| Parameter | Superdrol Injectable (40mg/ml) | Superdrol Oral (10mg/tab) |
|---|---|---|
| Route | Intramuscular injection | Oral tablet |
| First-pass hepatic exposure | Bypassed — systemic delivery only | 100% first-pass through liver |
| Hepatotoxicity | Reduced — still present systemically | Severe — first-pass concentration |
| Bioavailability | Near-complete via IM | Moderate — first-pass metabolism |
| Convenience | Injection required | Oral tablet — most convenient |
| Dose precision | Volume-based — flexible | Tablet-based — 10mg increments |
| Same anabolic compound | Yes — identical active molecule | Yes |
Dosage and Administration
| Protocol | Dose | Frequency | Duration |
|---|---|---|---|
| Standard performance | 20–40 mg/day | Daily IM injection | 4–6 weeks maximum |
| Conservative start | 20 mg/day (0.5ml) | Daily | Assess hepatic response before escalating |
At 40mg/ml, a 0.5ml daily injection delivers 20mg; a 1ml injection delivers 40mg. The IM injection route is typically gluteal, vastus lateralis or deltoid — rotating sites daily. Because hepatotoxicity is reduced but not eliminated, cycle length is still strictly limited to 4-6 weeks, which is somewhat longer than the 3-4 week oral cycle maximum due to the reduced first-pass load. Liver enzyme monitoring remains essential throughout.
Side Effects
- Hepatotoxicity — reduced versus oral form but present; liver enzyme monitoring remains essential throughout any injectable Superdrol cycle
- Lethargy — same pronounced fatigue as oral Superdrol; inherent to the compound regardless of route
- No aromatisation — no estrogenic side effects from the compound itself
- Suppression of natural testosterone — Post Cycle Therapy required
- Blood pressure elevation — common; monitor throughout
- Injection site discomfort — daily IM injection requires site rotation
Protocol Context
- Enantat 250 or other testosterone base — injectable Superdrol is added as a mass/strength compound to a testosterone foundation
- Never combine with oral 17-AA compounds — injectable route reduces but does not eliminate hepatic burden; stacking with oral AAS negates the hepatotoxicity advantage
- Clomid or Nolvadex for PCT
"Injectable Superdrol bypasses the first-pass hepatic concentration that makes the oral form so liver-toxic — delivering Methyldrostanolone's exceptional anabolic effect with a meaningfully reduced hepatic burden compared to swallowing the same dose as a tablet."
Storage and Handling
Store Superdrol Injectable at room temperature away from direct sunlight and heat. Use sterile technique for every draw — fresh needle for drawing, separate needle for injection.
