Nandrolone

Research Papers and Clinical Trials

Research on nandrolone has focused on several distinct areas, with studies examining both therapeutic applications and potential adverse effects.

Preclinical Studies

Recent animal research has investigated nandrolone's effects on various organ systems. A 2026 study in the Journal of Molecular Histology examined protective effects of cumin oil against nandrolone decanoate-induced liver injury in rats, suggesting potential hepatotoxic effects of the compound. Another 2026 study published in Clinical and Experimental Reproductive Medicine evaluated prepubertal exposure to nandrolone combined with royal jelly in male mice, finding alterations in testicular structure and sperm production through histomorphometric analysis.

A behavioral study in Hormones and Behavior (2026) examined whether supraphysiological androgen administration, including nandrolone, provided additional benefits for brain plasticity markers and behavior in untrained male mice. The research found no additive benefits beyond physiological levels.

Clinical Trials

Several clinical trials have explored nandrolone's therapeutic potential:

Sarcopenia Treatment: A Phase 2 trial (NCT05978206) is currently recruiting participants to study nandrolone's effectiveness for sarcopenia treatment when combined with physiotherapy and dietary interventions.

Telomeropathies: A completed Phase 1/2 trial (NCT02055456) investigated nandrolone decanoate for treating telomeropathies, though detailed results are not provided in the available evidence.

Cancer-Related Malnutrition: A completed study (NCT03263520) examined nandrolone's impact on cancer-induced malnutrition, though the phase designation was not specified.

Performance Enhancement: An ongoing invitation-only study (NCT07568574) is examining medically supervised performance-enhancing substances, including nandrolone, in elite athletes.

Evidence Limitations

The available evidence is limited by the small number of completed studies with published results. Most clinical trials listed are either still recruiting participants or have completed enrollment without detailed outcome data available. The preclinical studies, while informative about potential mechanisms and effects, are conducted in animal models and may not directly translate to human applications.
