What is in Chaotic Pump
L-citrulline (6,000 mg) and arginine (200 mg). These are the main pump ingredients on the panel. The NIH Office of Dietary Supplements (ODS) says research to date does not provide strong support for taking citrulline, and that arginine at 2 to 20 g a day has little to no effect on performance. So treat the pump as the brand's promise rather than a proven outcome.
Agmatine sulfate (1,500 mg), alpha GPC 50% (400 mg) and huperzine A (100 mcg). None of these is named in the Australian Institute of Sport (AIS) Sports Supplement Framework groups, so there is no AIS guidance on them. Any focus or pump benefits are the brand's claims.
Coffee fruit extract (100 mg, yielding 7 mg of caffeine). That is a very small amount of caffeine. The AIS says caffeine's performance benefit comes at about 2 to 3 mg per kg of body weight (around 200 mg), so Chaotic Pump is not built around caffeine. The AIS also notes caffeine can affect sleep even at low intakes, so evening users should still watch how they sleep.
Himalayan pink salt (200 mg), potassium citrate (75 mg), AstraGin (30 mg) and vitamin B3 (13 mg) round out the panel. AstraGin is listed on the label as astragalus and Panax notoginseng root extracts.
Who it suits
- People who train in the evening or want a low-caffeine pre-workout.
- Lifters who already get caffeine from coffee and want a pump product without doubling up.
- Experienced users comfortable with a multi-ingredient formula.
- Anyone who prefers a smaller 20-serve tub to try a product.
Who should check first
- Under 18, pregnant or breastfeeding: talk to your doctor before using any pre-workout.
- Medical conditions or medication: ask your doctor or pharmacist first, especially if you take regular medicines, as the formula has several active ingredients.
- Caffeine: it has about 7 mg per scoop. Count it with your coffee, energy drinks and any other pre-workout on the same day.
- Allergies: the panel we checked lists only the active ingredients. Read the full ingredient list and allergen statement on the tub.
- Drug-tested athletes: a Sport Integrity Australia survey found 35% of 200 supplements bought online in Australia contained a prohibited substance, with pre-workouts among the most likely to be contaminated. Sport Integrity Australia points to HASTA or Informed Sport certified products. Read our guide for drug-tested athletes.
How to use Chaotic Pump
The panel we checked lists a serve of 1 scoop (11 g) and 20 serves per tub, but does not show mixing directions. Follow the directions printed on your tub for water and timing, and do not exceed the recommended serve.
If you are new to pump pre-workouts, start with half a scoop to see how you respond. If you stack Chaotic Pump with a caffeinated pre-workout, add up the caffeine. FSANZ advises healthy adults to have no more than 400 mg of caffeine a day from all sources and no more than 200 mg in a single serving, and pregnant or breastfeeding women no more than 200 mg a day. Read our pre-workout caffeine guide.
How it compares
- Chaotic Rage by Mad House Innovations: the stimulant sibling. A 15.3 g scoop lists 200 mg of caffeine anhydrous plus di-caffeine malate yielding 37.5 mg (237.5 mg in total), and 3,500 mg of beta-alanine.
- Evogen EVP AQ: a liquid with 20 g of vegetable glycerol and 2.5 g of betaine per full 2 tablespoon serve, and no caffeine listed. Evogen says it can be taken alone or stacked.

FAQs
Does Chaotic Pump contain caffeine?
Only a little. The 100 mg of CognatiQ coffee fruit extract yields about 7 mg of caffeine per scoop, compared with 237.5 mg in a scoop of Chaotic Rage.
Can I stack Chaotic Pump with a stimulant pre-workout?
You can, but add up the caffeine from both products first. FSANZ advises healthy adults to keep to 200 mg of caffeine in a single serving and 400 mg a day from all sources. Start with half a serve of each.
Is Chaotic Pump good for beginners?
It can suit beginners who want to avoid high caffeine, but it is a multi-ingredient formula. Start with half a scoop and follow the directions on the tub.
When should I take Chaotic Pump?
Follow the timing printed on your tub. With about 7 mg of caffeine per scoop it is far lower in caffeine than a stimulant pre-workout like Chaotic Rage, so it can suit evening sessions. The AIS notes caffeine can still affect sleep even at low intakes.
Is Chaotic Pump suitable for drug-tested athletes?
The information we checked does not mention batch testing or certification. If you are tested, choose a product certified by HASTA or Informed Sport and check with your sport before use.
