lamp, try 27 grams of high GI carbs. Plus it has no fat. Myoplex MRP's wouldn't even pass for a clean or balance meal for a bodybuilder, not to mention using as a pre-workout meal.
Bro, I find some natural peanut butter, or a big hunk of swiss work great for me pre-workout, but I do low carbs year round and am used to burning ketones for fuel, so it may not work as well for you. At the very least, you do not get bloating from them, even when drinking a lot of water during your workout.
