What is Superdrol?
Superdrol (Methasterone) is an oral, 17a-alkylated DHT derivative - one of the harshest and most potent oral steroids. It delivers fast, dry strength and mass gains without aromatization but is extremely liver-loading and worsens lipids and blood pressure strongly.

Comparison
Methasterone and relatives
The same compound in oil and related steroids at the same receptor, as stated in the TPD lexicon. Tap a card to open its entry.
Simplified: methasterone is drostanolone with an extra methyl group at position 17. This group makes it work as a tablet and is seen as the reason for the liver strain. 1012
How it works
Methasterone activates the androgen receptor very strongly and does not aromatize - hence dry gains without water retention. The high potency comes with a correspondingly harsh side effect profile, especially on liver and lipids.

What the research shows
Methasterone was a popular designer steroid of the 2010s. Compound-specific human studies are scarce; the AAS pharmacology (Kicman 2008, Hartgens & Kuipers 2004) classes the properties of oral 17a-alkylated DHT derivatives.

Anabolic and androgenic compared10
Effect as a multiple of methyltestosterone (= 1), orally in rats
Values from the 2012 DEA classification, which cites a 1960 paper (four times as anabolic, one fifth as androgenic). Further tests for the DEA: given orally and under the skin to castrated rats it acted like testosterone and binding to the androgen receptor was comparable.
How certain was the steroid the cause?2
Assessment of 52 published liver injuries using the RUCAM score
Case reports, not a trial. The review covers 2 own and 50 published cases with different steroids. Tissue samples showed bile congestion in the liver.
When the liver injury showed2
Median of the 52 cases in days (d)
The injury can still get worse after stopping. In a series of 5 methasterone cases jaundice appeared 2 weeks after stopping and everything had healed about 12 weeks after presentation.
Research status
Where the research stands
Methasterone was first made in 1956 and never tested in humans. ClinicalTrials.gov lists not a single trial. As of 26 Oct 2026. 11
- Preclinical Animal model (rats, oral and under the skin) and receptor cell assays
- Phase 1 no registered trial
- Phase 2 no registered trial
- Phase 3 no registered trial
- Approval not yet
So far there is no registered trial in humans. 11
Side effects
- Liver: 17a-alkylated, extreme - ALT/AST can rise dramatically. Short cycles, liver support mandatory.
- Lipids: catastrophic HDL lowering.
- Blood pressure: rises markedly.
- HPTA suppression - PCT topic.
Tolerability
Severe courses in the case reports
Out of 100 published cases of steroid liver injury, how many had this. Case reports, not a trial, no comparison group.
Case reports only show what was reported, not a rate among all users. A single case describes IgA nephropathy, an inflammation of the kidney filters, after a muscle building product with methasterone.23
Storage
