TRT overrides your hormones. It doesn't restore them. The shortage that caused your low T stays exactly where it was. Reindeer thrive where most mammals would perish — Arctic cold, scarce forage, brutal terrain. Their organs concentrate hormones, vitamins, and mitochondrial cofactors at levels no farmed animal can match.
The same organs Viking warriors and Sami hunters ate to stay strong, fertile, and dangerous into old age. Fed those compounds, the pathway your testes use to build testosterone finally has what it's been starving for. Your body builds your levels back — the way nature intended.
