Research Reference Ranges
Common reference ranges for 4-Chlorodehydromethyltestosterone in non-medical contexts are not well characterized in publicly available bodybuilding resources, and no FDA-approved human dosing information exists. Historical clinical dosing referenced up to 50 mg daily for recovery after surgery. In non-medical bodybuilding contexts, 4-Chlorodehydromethyltestosterone is commonly referenced at 30–60 mg daily for 4–8 weeks, with split dosing providing more stable blood levels. These figures are anecdotal and lack clinical validation for non-medical use.

Stacking & Cycle Considerations
In non-medical bodybuilding contexts, 4-Chlorodehydromethyltestosterone is sometimes stacked with a testosterone base. A typical combination referenced is TRT-dose testosterone (100–200 mg/week) with 4-Chlorodehydromethyltestosterone at 30–60 mg daily. However, the compound is not FDA-approved for human use, and no clinical data exists to support any combination with other compounds.
Because 4-Chlorodehydromethyltestosterone is 17-alpha-alkylated, concurrent use with other oral 17-alpha-alkylated steroids increases hepatotoxicity risk. It is banned by WADA and is prohibited at all times in sport.
Managing Research Risks
4-Chlorodehydromethyltestosterone is associated with hepatotoxicity due to its 17-alpha-alkylated structure. Rare but serious risks include cholestatic jaundice (yellowing of skin/eyes, dark urine, pale stools, severe itching), peliosis hepatis, and hepatic adenomas with prolonged use. Liver function tests should be monitored if use is considered.
Cardiovascular risks include adverse lipid changes, particularly reduced HDL cholesterol, and potential hematocrit elevation. Thrombotic events have been associated with anabolic steroid use, and the combined lipid/BP/hematocrit package raises clot risk.
Other potential adverse effects include suppression of natural testosterone production, acne, accelerated hair shedding in genetically predisposed individuals, and for women, virilization symptoms (voice deepening, clitoral sensitivity, body hair changes) which may be irreversible.
Post-Cycle Considerations
4-Chlorodehydromethyltestosterone suppresses endogenous testosterone production, and post-cycle therapy is commonly recommended in non-medical contexts. Because the compound has a short half-life (approximately 16 hours) and no ester to clear, standard SERM PCT can begin approximately 3 days after the last dose. A typical protocol referenced includes nolvadex 40/40/20/20 mg over 4 weeks, or clomid 50/50/25/25. Agents such as Clomid or Tamoxifen are commonly referenced for this purpose.
