Pump Addict is used in actual supplement names, so the phrase does not simply mean a lifter chasing a pump. Believe Supplements sells Pump Addict Max and Pump Addict SF; Muscle Addiction sells a separate Pump Addict Ultra Hardcore. Check the brand and suffix before assuming a product is stimulant-free. This guide reviews manufacturer pages and label images checked October 12, 2026, without personal testing.
Believe Pump Addict Max: notice the half-scoop label
The official Max page links a panel defining one serving as half a scoop, 10.6 g, with 40 such servings. Selected amounts per half scoop are:
- Caffeine: 175 mg
- Citrulline malate: 4,080 mg, declared to provide 2,285 mg L-citrulline
- Beta-alanine: 1,750 mg; betaine: 1,250 mg
- L-tyrosine: 500 mg; L-theanine: 100 mg
- Agmatine sulfate: 400 mg
- Alpha-GPC 50%: 500 mg material, declared to provide 250 mg choline alfoscerate
The page’s comparison chart uses full-scoop figures including 350 mg caffeine and 20 servings. Those two caffeine and serving-count presentations agree once the half-scoop versus full-scoop basis is accounted for. That arithmetic is not a recommendation to double the labeled serving.
An Alpha-GPC discrepancy remains
The chart labels Alpha-GPC 50% as 500 mg on its full-scoop basis. Doubling the linked half-scoop panel instead gives 1,000 mg of 50% material, providing 500 mg choline alfoscerate. The displayed Tropical Orange front image also prints 250 mg beside Alpha-GPC 50%, whereas the half-scoop panel lists 500 mg material. The sources do not consistently distinguish material weight from active yield. The front also shows 430 g net weight, while 40 times the shared panel’s 10.6 g serving is 424 g, a 6 g difference. Neither mismatch is resolved by the page. Ask Believe to confirm the exact flavor and lot rather than treating those numbers as interchangeable.
Believe Pump Addict SF: a separate stimulant-free formula
The official SF page describes this version as caffeine- and stimulant-free. Its linked panel lists a 14 g scoop and 25 servings, with 6,000 mg citrulline malate, 2,000 mg agmatine sulfate and 1,000 mg leucine. It also lists glycerol monostearate, pink salt and trisodium citrate.
Mineral compound weights need their qualifiers: the panel’s 150 mg potassium citrate provides 55 mg potassium, and 150 mg magnesium glycinate provides 22 mg magnesium. Do not report each as 150 mg of elemental mineral. Similarly, the 6,000 mg citrulline-malate entry is not a declaration of 6,000 mg pure L-citrulline.
Muscle Addiction Pump Addict Ultra Hardcore
Muscle Addiction’s product is another formula entirely. Its Candy Explosion panel gives one scoop as 7.57 g and two as 15.14 g. It declares 150/300 mg caffeine anhydrous, 3,000/6,000 mg L-citrulline and 1,500/3,000 mg betaine for those respective amounts. Additional entries include N-phenethyl dimethylamine, theobromine, methylliberine, theacrine and rauwolscine. It is not a caffeine-free pump powder.
Do not apply the Believe SF directions or ingredient amounts to this product merely because both names contain Pump Addict. Read its complete panel and container warnings.
How to compare them meaningfully
- Record the manufacturer, complete name, country label and flavor.
- Write down the serving in grams and whether the figures use half, one or two scoops.
- Distinguish ingredient-material weight, active yield and elemental mineral amounts.
- Review every stimulant entry and caffeine from drinks and other supplements.
- Ask the manufacturer to clarify inconsistent information before relying on it.
The FDA’s caffeine guidance emphasizes individual sensitivity and relevant medications or conditions. A stimulant-free label also does not establish that every other ingredient suits every person. Check the full product with a clinician or pharmacist when needed.
Finally, NIH’s exercise-supplement review distinguishes ingredient research from evidence for finished combinations. A larger pump, a tingling sensation or a product name does not prove greater muscle growth or faster recovery. Commercial alternatives pictured elsewhere are separate products with separate labels.
