I started using MTN OPS Ignite solely because it was offered on Guidefitter. Now, I am hooked. I take 1 scoop every morning before a workout and I feel great after. It doesnt give me the jitters or make my skin feel itchy like some other powders do a few minutes after drinking. The scoop and suggested water usage, are larger than previous powders I've tried, but the flavor is great so I cant really complain too much.
