Last. Neurogenesis is a slow process, yes. But i feel some improvement after taking it for almost a month actually. It helps against anxiety and depression also. And NGF: Nerve growth factor - Wikipedia

And all of the scientific evidence was in the youtube video i linked before, and i have also read about the rats in neurogenesis. (Pubmed.) I'm really happy i stumbled across it a while back. The mushroom is unique in NGF and neurogenesis. I will try it out for 6 months or more and see what happens.
I'm loving it. Anyways, we can write on here another time. Peace out. Good night
