Although the study was on rats, the same probably applies to men. The dose was large 2 mg/kg/d of testosterone propionate, which translates to 160 mg/d for an average sized man, a large dose even for a bodybuilder. The article concludes:
"In conclusion, we have provided evidence supporting androgen as an anti-renal fibrosis medicine. Our studies provide the molecular basis for TP [testosterone propionate] may alleviate the age-related renal fibrosis via suppression of TGF-β1/Smad signaling and activation of Nrf2-ARE signaling in aged rats."
