Ammo from Mtn Ops is awesome, tastes great, and really works. I've used it off and on for years, but got serious with it this April. Using it in combination with Magnum from Mtn Ops and a fairly strenuous daily workout routine, I've lost 56 pounds. I've felt great the whole time and have gotten off my blood pressure meds.
Ammo also blends really well. All the flavors are good, but my favorite is the good old chocolate flavor, which I blend in unsweetened almond milk.
