…discussing Tongkat Ali supplementation for testosterone production
“We can talk about things that affect the steroidogenesis cascade. So we could touch on Tongkat Ali. Also known as Long Jack, and that upregulates several different enzymes in the steroidogenesis cascade. Anywhere from 300 to 1,200 milligrams a day. With Tongkat, you need to be careful with the standardization because if you're thinking about a general Tongkat supplement, which is by far the most well-studied, then you're looking at the uricominone content, which is a plant compound that is likely the main active pharmacologic effect.”

…discussing supplements with peer-reviewed research for increasing libido
“Another substance that has been shown to increase libido across a range of human populations is so-called Tongat Ali. This is an herb. There's a Malaysian version and an Indonesian version. My understanding is that the Indonesian variety of Tongat Ali is the one that is most potent for its effects on libido. Previously, I've talked about Tongat Ali taken in 400 milligram per day capsules as a means to increase the amount of free, meaning unbound testosterone.”
