I've taken phen dozens of times over the past couple years but why is it always recommended to take phen and caffeine at exactly the same time? What I'm getting at is if it takes me about 3 hours before I feel the effect of phen, wouldn't I want to then take caffeine at the 3 hour mark?
Same thing with kratom too as I see people recommending both simultaneously, isn't this kinda defeating the purpose of the intended effect?
