48 serving tub that just does not cut it, Magnum’s Opus is half of what Jack3d offers

Magnum Nutraceuticals is not a well known brand but their new Opus pre-workout has been popping up for quite a few people. It contains 48 servings with a maximum of two per day. It is apparently stimulant free so expect about half or less of a pump that DMAA infused supplements.

Available in just one flavor, cellular punch, you will be a lot better off with your current pre-workout.
