It looks like Dymatize Nutrition has replaced their current pre-workout Xpand 2x with the new M.P.ACT.

M.P.ACT essentially has same ingredients as Xpand 2x, but they’re now consolidated into 3 different performance blends. If you’ve had a chance to try Xpand 2x, you’ll already have an idea of how you’ll like the new M.P.ACT.

A Formidable Duo

I was initially disappointed to see that M.P.ACT still features a proprietary blend. That being said, M.P.ACT does have a solid ingredient profile. Agmatine sulfate is one of my favorite ingredients right now for pump, and I was glad to see it in here.

To further help with getting a good pump, you’re also going to get beet root extract. Research shows beet root can lower blood pressure and improve vasodilation, delivering more blood and nutrients to muscles for better growth and recovery. [1]

Sticking To The Basics

If it ain’t broke, don’t fix it. There’s a reason ingredients like creatine monohydrate and betaine are in almost every pre-workout. These are two of the most researched and effective ingredients for increasing strength, lean mass, and improving overall exercise performance.

You’re most likely familiar with the benefits of creatine monohydrate─ increased strength, lean mass, and better body composition. [2]

Beta alanine works by saturating muscles with carnosine. This improves muscle ph balance, preventing lactic acid from building up so quickly and delaying the time it takes to feel that burning sensation in your muscles during a set. [3]

Although creatine and beta alanine are effective individually, studies show they work synergistically and are even more effective when combined.

One study showed that subjects supplementing with both creatine monohydrate and beta alanine experienced decreased muscle damage and less oxidative stress.[4]

Ingredients To Grow On

As I mentioned above, there’s quite a few ingredients amongst the different M.P.ACT blends. A few additional ingredients you’ll find to help with growth and recovery are branch chain amino acids (BCAA’s), rhodiola rosea, tyrosine, and caffeine.

M.P.ACT has 200 mg of caffeine per serving, but it looks like Dymatize is also coming out with a caffeine free version.

How My Workout Went With M.P.ACT

I will say that I was pleasantly surprised by M.P.ACT. If you don’t mind the caffeine I would definitely recommend taking at least 2 scoops, as the creatine and beta alanine is ostensibly underdosed with just 1 scoop.

However, I took 2 scoops and that definitely did the trick. I had great muscle pumps, and definitely felt stronger during my sets.

M.P.ACT Taste, Price, and Availability

You’re looking at a dollar per serving for M.P.ACT, as a 30-serving container can be found at most retailers for about $30. The “Cool Watermelon” flavor is also on point, and I loved drinking it.

Unfortunately, there’s a good chance you’ll need at least two servings to reach recommended dosages of ingredients like creatine and beta alanine. This means a $30 container would only last you 15 workouts.

M.P.ACT Final Thoughts

As long as you take at least 2 scoops, M.P.ACT is a great pre-workout that’s going to help you get better pumps, increase strength, and give you the motivation and energy to lift.
