DOES IT WORK?
Results vary. 7,8-DHF is genuinely exciting in preclinical research. It crosses the blood-brain barrier and activates TrkB receptors just like BDNF does. Animal studies are impressive. But there are zero human clinical trials, and we don't know the right dose, safety profile, or whether it actually works in people.
