8. Evogen – EVP

Created and owned by the “fitness guru” himself Hany Rambod, EVP was one of the first brands making the stimulant free PWO supplements, and the formula actually works well.

However, since then many new brands and formulas have hit the market.

Another reason why we couldn’t rank it any higher was because the formula consists of a major proprietary blend so unfortunately without knowing what amounts of each ingredient is in there we cannot rank it any higher.

Overall though, this is a decent non-stim PWO that will definitely help you in the gym.

Also, it may be important to not get their EVP non-stim mixed up with their caffeinated version EVP Plus.

Highlights for Evogen – EVP

  • Evopoietin 1-Alpha Proprietary Blend – 9.22g
  • Promote Muscle Pumps
  • Enhance Performance
  • Average Price

7. PEScience – High Volume

PEScience has become a known brand in the recent years, especially for their great tasting, clean protein powder Select.

They have continued to produce quality products and it proves with the release of High Volume, their stimulant free PWO.

High Volume is another simple formula that contains citrulline, arginine nitrate, agmatine sulfate, and a “performance pump matrix”.

While this is a decent formula, what you might want to watch out for is their labelling; for example it says there is 4-grams of l-citrulline but this is per 2 scoops. If you plan on taking 2 scoops there will only be 18 servings per tub, which isn’t a lot for their retail price. Along with this, and their formula containing a proprietary blend it ranked in at #7 on our list.

Overall, if you’re looking for a decent pump formula and have the extra cash, this product could be a good option for you.

Highlights for PEScience – High Volume

  • Serving Size is Per 2 Scoops
  • Creatine Free
  • Performance Pump Matrix Formula

6. Core Nutritionals – PUMP

Created and owned by Doug Miller, known as the top professional natural bodybuilder around.

Once Doug left his full-time job and pursued Core Nutritionals, they’ve relabelled and a lot of reformulating on their products, along with releasing some which is why their stim-free PWO PUMP earned #6 on our list.

This formula is simple and contains no proprietary blends with an average price point.

In the PUMP formula there is agmatine sulfate, citrulline, hydromax, and nitrosigine. At stronger dose per scoop versus high volume, using 2 scoop is an option but not necessary for most people. It was only ranked at #6 because this formula could use a couple more ingredients to make it a completely rounded stim-free PWO. However, if you’re looking for a decent PWO without wanting to double scoop this is a good option.

Highlights for Core Nutritionals – PUMP

  • No Proprietary Blends
  • Creatine Free
  • Hydration
  • Promotes Intense Pumps
  • Citrulline – 3g (Per Scoop)

REDCON1 came in swinging with their stim-free PWO Big Noise and it’s gathered some positive attention.

This is a good proprietary blend free formula that will help you stay focused and ready to workout.

What some people may not like about this non-stim pre is the fact that its formula does not contain any citrulline, which a lot of people enjoy taking in their caffeine or caffeine free PWO’s.

However, this formula does include Alpha-GPC to help with focus, mood, and more.

One more ingredient worth the mention in this formula is betaine anhydrous that is not often found in any type of PWO’s, so good job to them on putting it in there.

  • Promotes Great Pumps
  • Increased Focus & Performance
  • No Citrulline Malate
  • Average Pricing

A combination of these ingredients at fair doses will allow you to get the pumps necessary for a solid workout.
