About the 5htp not being able to cross the blood brain barrier. I remember reading somewhere on bluelight that if you mix vitamin b6 and 5htp they will react and and the 5htp transforms into 5ht and this can`t cross the blood brain barrier. Could this be what you rememberered?
As for how fast 5htp works. I feel happy and slightly euphoric right after I take them and then I get rushes like 15 min after ingestion. And I remain happy for the rest of the day.
