⚠ LIMITED HUMAN DATA. Small Phase I/II trials conducted by WHO/NICHD for male contraceptive research — key differentiator from trenbolone/metribolone. Some legitimate human pharmacokinetic data exists. Not approved for any indication. Male contraceptive research ongoing but stalled. Most promising human research application among the no-approval compounds.
7α-methyl-19-nortestosterone. Does not require 5-alpha reduction for activity (unlike testosterone). Aromatizes to 7α-methyl-estradiol. High AR and progesterone receptor binding. Studied by WHO and NICHD as male contraceptive — suppresses spermatogenesis while maintaining androgenic function. Potentially no 5-alpha reductase activity means no prostate/scalp DHT amplification.
Limited human Phase I/II data (WHO contraceptive trials); no FDA approval; aromatizes; no 5-alpha reduction; progesterone receptor binding; male contraceptive research.
Research data is not a treatment plan. If you are considering MENT (Trestolone Acetate), the questions that matter are whether it suits your history, your labs and your goals. That is a conversation with a licensed physician, not a lookup.
