What the evidence says
Veterinary compound (horses, cattle) diverted for human use. Slow gains but cleaner side effect profile than stronger AAS. Notorious for driving hematocrit to concerning levels (>55) requiring therapeutic phlebotomy. Very long detection window for sport.
Mechanism
Structurally testosterone with 1,2-double bond (effectively dianabol without C17-aa); mildly aromatizes; slow-acting; veterinary horse compound
Studied, labeled, or reported dose & route
Illicit: 300-600 mg/week IM (undecylenate ester)
This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.
