Harness by Arms Race Nutrition Overview

Harness is the first product that was introduced by Arms Race Nutrition, a collaboration between Julian Smith and natural pro-bodybuilder Doug Miller. This is Doug’s third brand. The premise is to use only science based, proven ingredients, with a hint of an old-school mentality.

Judging by the formula, Harness appears to be a strong pre-workout formula. I can understand why they suggest that everyone start with one scoop, instead of the full two-scoop serving size.

For every two scoops, you are getting 5 grams of straight L-Citrulline. If you don’t get a pump from that, then I don’t know what to tell you. Not only does ViNitox, a combination of L-Ornithine, L-arginine, and nitrates, help give you a better pump and help with performance in the gym (10% increase in training time and a 13% increase in delaying fatigue), but it can also help with performance in the bedroom. Yep, ViNitox has been shown to have promising affects on the deadly, and embarrassing, erectile dysfunction (ED).

Not only will it help with both workout and bedroom pumps, but Harness will get you going. Yep, it’s loaded with stimulants. 350mg of Caffeine Anhydrous and 75mg of ZumXR XR Caffeine combined with 150mg of ElevATP should work for almost any stimulant junkie out there. And then there is 250mg of Citicoline, which will help get you focused on destroying any weight that dares to stand in your way.

When choosing a pre-workout supplement, you should look for the following four things: Increased energy, improved focus, enhanced pumps, and better recovery. Well, it appears that Harness by Arms Race Nutrition checks all the boxes. After we get our hands on a tub or two, we will let you know what we think.
