§ 04 — SCIENCE

Clinical trials demonstrate that testosterone enanthate effectively restores serum testosterone in hypogonadal men and attenuates lean mass loss during severe energy deficit. A 26-week subcutaneous auto-injector study confirmed a stable pharmacokinetic profile with trough levels maintained in 82-83% of patients. Comparative studies show subcutaneous TE produces lower estradiol and hematocrit elevations than intramuscular testosterone cypionate. In gender-affirming therapy, TE achieved desired masculinizing effects comparable to testosterone undecanoate over one year. Behavioral studies at 200 mg/week during energy deficit did not reliably alter aggression, mood, or cognition. Evidence for supraphysiological performance-enhancing use is largely observational and confounded by selection bias.
