Does my intake and cycling schedule for tongkat ali and fadogia agrestis correspond with Andrew Huberman's recommendations from the episode Optimize Sleep, Enhance Performance, and More | Dr. Andrew Huberman and the clip Testosterone Insights? I take 400mg daily of tongkat ali with 3% eurycomanone and 600mg fadogia agrestis at a 20:1 ratio, and I've been doing so for a couple of years. Blood tests show a moderate increase in testosterone, and I have felt an increase in libido and vitality. I take them together in the morning with a little yogurt to aid mild nausea caused by the tongkat ali, and I cycle these supplements with eight weeks on and two weeks off.
