Regulatory consensus
3 regulatory and scientific bodies have classified Clenbuterol. The classifications differ — that's the data.
| Agency | Year | Classification | Notes |
|---|---|---|---|
| FDA | 1998 | Approved vet drug — horses only; banned in food animals | |
| EU | 1996 | Banned as growth promotant | |
| WADA | 2004 | Prohibited substance |
Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.
