I agree. I’d like to try Plazma, but honestly $67 for as few servings as there is - I just can’t afford that. I’m an at-home, basement lifter - not a competitor. I am looking for a boost in the mornings (since I left around 5am) and sustained energy, and that’s about it.
What is karboline? Google search returns nothing (in English).
And so I guess I don’t understand. Looking up DMAA, it looks like it is banned by the FDA, has all kinds of nasty side effects, and you are saying it’s amphetamine. How can this be on the market??
…and now I’m stuck with a bottle that I’ve got to finish, because I’m too cheap to dump it down the drain. 
Any suggestions on a good pre-workout that ISN’T a banned substance?
