Core Nutritionals is no stranger to launching stacked new supplements for the Arnold Sports Festival; we saw exactly that a couple of years back with the reveal and release of its absolutely loaded, premium pre-workout Ascension. That product has since been discontinued, although at the end of this week, for the 2026 edition of the Arnold Expo, the reputable brand is doing it all again with the debut of a premium pump-powering pre-workout.
For this year’s Arnold Sports Festival, Core Nutritionals is launching Pump Black, a special edition version of its already available, stimulant-free supplement, Pump. The upcoming Pump Black is a much more jam-packed offering, with a huge 27g serving, breaking down in a total of 20g of actives. The formula has been crafted specifically to enhance muscle pumps, performance, and focus, similar to the regular Core Pump, but with a wider variety of ingredients.
You can see the complete set of components and dosages in Core Nutritionals’ Pump Black directly above, and it is not short on highlights. In a full serving, you get 10g of straight citrulline from pure citrulline and NO3-T citrulline nitrate, 3.2g of beta-alanine also from regular and NO3-T beta-alanine, and then 2.5g of a blend of regular and NO3-T betaine nitrate. That takes care of the pump and performance promises in the special edition product, with tyrosine and Cognizin in there too to drive up focus and cognition.
As mentioned, Pump Black is a ramped-up version of Core Nutritionals’ original stimulant-free pump-enhancing pre-workout Pump with simply more for pumps and focus, especially thanks to the NO3-T nitrates and Cognizin. Again, the brand is releasing the premium pre-workout at the end of this week, at the Arnold Sports Festival in Columbus, Ohio, as well as through its website, in tubs of 20 maximum servings and a flavor called Red Alert.
