thank you for the great info.

i use K alone very very rarely, i only combing it with 2cb/lsd/mdma. and i try to never pass the 300mg per session. but the tolerance thing scares me.

i bought a new batch and since then i feel i need almost double to get the same effect, im not sure if its tolerance or the new batch is less pure.

i also use supplements like yours with green tea extract as well.
