A tip for the sports fans, if you do a lot of cardio exercise (jogging, running, cycling, swimming etc) you should try to use Beta Alanine and citrulline malate together with kratom before you start your exercise. It gives me tremendous endurance and can keep going lots longer without getting tired.

I also use the combination with my weight lifting and it also seems to work rather well here. Kratom for the focus, and beta alanine and citrulline malate for the increase in strenght and endurance it seems a great combination
