The Claim
Four weeks of 200 mg/day Tongkat Ali supplementation increases the cortisol-to-testosterone ratio by 36% in moderately stressed adults, indicating a shift toward a more anabolic hormonal environment that reduces stress-induced catabolism.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 200 mg of Tongkat Ali daily for four weeks increases the cortisol-to-testosterone ratio by 36% in adults with moderate stress, which is associated with a hormonal shift that reduces muscle breakdown caused by stress.
See the scientific wording
The cortisol-to-testosterone ratio improves by 36% after four weeks of 200 mg/day Tongkat Ali supplementation in moderately stressed adults, suggesting a shift toward a more anabolic hormonal environment that may counteract stress-induced catabolism.
Bioactive compounds in Tongkat Ali bind to a protein that holds testosterone in the blood, freeing more of it to act on tissues. At the same time, these compounds activate an enzyme that makes more building blocks for testosterone. This raises testosterone levels. The same compounds also reduce signals that tell the body to make stress hormone, lowering cortisol. Together, this shifts the balance toward muscle-building and away from stress-driven breakdown.
What the research says
1 studyTaking 200 mg of Tongkat Ali daily for four weeks lowered the stress hormone cortisol and raised the body-building hormone testosterone in stressed adults, making their hormone balance 36% better — just like the claim says.
