Checked 2026-11-10. Independent clinical review has not been completed. WADAFUK is independent of WADA and does not provide medical advice or an individual anti-doping determination.
Regulatory summary with limited context. A compound-specific science and safety review is still missing.
Prohibited at all times
4-Androstenediol is covered by S1.1 of the effective 2026 WADA List and is prohibited in and out of competition. S1.1 applies to exogenous administration; its coverage is not limited to the named examples and includes relevant esters. [2]
S1.1; 2026 List, printed pages 5–6 · 2026 rules apply from 1 January 2026. Any 2027 material below concerns future rules from 1 January 2027; it is not current clearance.
List year
The 2026 List is the effective edition on this review date. The checked 2027 S1 text showed no change, but the 2027 edition does not take effect until 1 January 2027. [2] [3] [1]

What remains uncertain
- Molecule-specific evidence was not sufficiently verified for a substantive public profile in this review. This is a rule-only entry, not a thorough molecule review; absence of reviewed evidence does not establish safety.
- Chemical registry identifiers, every alias and jurisdiction-specific product availability have not been exhaustively reconciled.
