I might be messing up the conversion but Plazma works out to, at most, $7 US per workout which is less than 6 pounds. Cut that cost in half if you use 1 scoop, which is fine for many lifters and/or easier workouts (like arm day vs a bigger workout like leg day).
Surge Workout Fuel uses the same basic ingredients as Plazma and is a legit alternative, and it's much less expensive at just over $2 US per workout.
I haven't seen a do-it-yourself version that matches all the ingredients at comparable doses and still works out less expensive. We could also factor in the time/hassle of scooping together a half-dozen powders before every workout vs using just one product. I'm just saying, the "homemade is cheaper and better" just doesn't pan out from what I've seen.
No-Doz. Under 10 bucks for a two month supply.
Surge Workout Fuel.
So, no protein/aminos or carbs?
