For the testosterone we prescribe at Male Excel, you will not see liver damage. If you use a synthetic “non-isomolecular” testosterone derivative like many body builders and athletes have abused, then yes it is highly likely you will get liver damage. You also primarily see this liver damage when testosterone is taken orally. You don’t see liver damage with “micronized” testosterone and bioidentical testosterone, especially when taken as a cream or injection as this bypasses the liver. A micronized hormone means that the hormones particle size is generally less than 50 microns. This means it is 4 to 10 times smaller than conventional drug particles and puts minimal burden on the liver.
