Jacked Factory pre-workout is a brand-level search, not one fixed formula. Nitrosurge is its caffeinated powder; Pumpsurge is a separate stimulant-free option. Nitrosurge Black and Shred names also appear in the brand’s range, so verify the complete product name before applying a label or review.
Nitrosurge: the standard label
The official Nitrosurge page identifies a creatine-free formula. Its displayed Supplement Facts graphic lists one scoop, 8.4 g, or two scoops, 16.8 g, with 30 or 15 servings. It gives:
- L-citrulline: 3 g / 6 g.
- Beta-alanine: 1.6 g / 3.2 g.
- Betaine anhydrous: 1.25 g / 2.5 g.
- Caffeine anhydrous: 180 mg / 360 mg.
- L-theanine: 90 mg / 180 mg.
- Theobromine: 50 mg / 100 mg.
- AstraGin: 25 mg / 50 mg.
These are one- and two-scoop amounts, not two competing formulas. Flavor-specific scoop weights and packaging can differ: the Watermelon tub pictured is labeled 240 g and 30 servings, while the displayed panel example uses 8.4 g. Use your own container’s matching panel.
How Pumpsurge differs
Pumpsurge is marketed without caffeine or other stimulants. Its ingredient list includes citrulline, betaine, glycerol, tyrosine and other components; it should not be treated as Nitrosurge with an identical label minus caffeine. A person avoiding stimulants should compare Pumpsurge directly rather than infer the entire brand is high-stimulant.
What matters in practice
Doubling Nitrosurge doubles the caffeine along with the pump-related ingredients. There is no requirement to progress to the maximum amount to make the purchase worthwhile. Compare the per-use cost at your intended serving rather than taking a 30-serving headline at face value for two-scoop use.
Beta-alanine tingling is not a measure of workout quality. Evidence for this ingredient generally involves regular supplementation over time, while research findings for multi-ingredient combinations cannot be assumed from each ingredient separately. NIH’s evidence review provides that broader context.
Count other caffeine sources, avoid combining stimulant pre-workouts, and stop use if you experience unwanted effects. Medication, medical conditions or pregnancy warrant professional advice before choosing a supplement. Caffeine-free products also need a complete ingredient and interaction check.
Comparing with Bucked Up
Compare a named Jacked Factory formula with a named Bucked Up formula at their actual serving sizes. Check total caffeine, ingredient forms, creatine and allergens first. Brand popularity or claims of transparency do not establish that one will outperform the other, and an ingredient list cannot predict your personal taste preference or results.
