I was going to resurrect this thread. Funny how it popped up. I was feeling like my stamina was decreasing lately, so I bought some SJW and 5htp about a month ago. So far I don’t think it is helping, just as I thought it didn’t help the other times I experimented. But I will give it more time.
I think SJW might give me some stress reduction if nothing else. I think 5htp may give me some weight loss (due to stomach discomfort) if nothing else.
I read that l-tryptophan works better than 5htp, because it somehow makes it to your brain better, whereas the 5htp ends up being consumed in the gut. But l-tryp is hard to find and you have to take a lot of it.
