transguys:

Have you ever worried about the possible long-term effects of being on Testosterone?

Well, you can relax because science has your back.

Italian researchers concluded in 2014 that “Testosterone administration in FtM subjects has a good safety profile” after finding “no significant serious adverse effects and no clinically relevant changes” in 45 FTM patients treated for at least 10 years with T.

Also notable: “Liver and kidney function tests did not show any significant changes.”

The aim of the study was to assess the effects and safety of Testosterone administration on body weight, lipid profile, hematological and bone parameters in trans men.
