The $4.5 Billion Testosterone Opportunity

Getting the Science Right

Wednesday 28 October, 12pm to 12.50pm Las Vegas time (PDT)Product Development Theater A, Bayside B, Level 1

Testosterone support is a $4.5 billion market growing about 10% a year, and the gap between claims and credible science is widening. Using Tongkat Ali as the case study, four experts look at why extract ratios mislead, and how standardisation and clinical evidence show what works.

The questions, in running order

  1. Where does Tongkat Ali come from, and why does that matter?Chris Kilham
  2. How much of its traditional use has clinical research confirmed?Dr Annie George
  3. How much Tongkat Ali does it take to get those results?Dr Annie George
  4. What does a ratio like 200:1 actually tell a buyer?Dr Stefan Gafner
  5. Who carries the risk when a product falls short?Dr Stefan Gafner
  6. What should a Tongkat Ali specification include?Dr Annie George
  7. What should a buyer ask their supplier tomorrow?All panellists
