Testosterone 101 - Legitimate Medicine or Unnecessary optimisation? | aGL x Dr. Mark Forbes
Notas do episódio
Most men with low testosterone don’t need TRT. They need to find out why it’s low.
Vascular surgeon Dr Venu Bhamidi sits down with endocrinologist Dr Mark Forbes, who has decades of experience treating hormonal and metabolic disorders, for a frank look at testosterone and the modern man. They cover what testosterone really does, whether “male menopause” exists, and the biggest hidden causes of low T: body fat, SHBG, overwork, poor sleep and untreated sleep apnoea.
Mark explains when you should actually get tested, how even a couple of doses of testosterone can switch off your natural production for months, and the real risks of TRT and steroid use. Those risks include thickened blood, heart rhythm problems, wiped-out sperm counts and shrinking testicles. He also gives his verdict on popular testosterone supplements, from zinc and magnesium to ashwagandha and Tongkat Ali.
Then Venu puts his own blood results on the table and has them read live, unseen, to show why you can’t make a diagnosis on a number.
Essential listening for men aged 25 to 65, for young men in gym culture, and for anyone thinking about starting testosterone.
