Alpha Lion Extreme means SUPERHUMAN Extreme, a named high-stimulant pre-workout. This guide uses the manufacturer’s current red-tub formula. Older Extreme reviews and packaging should not be treated as a specification for every product sold under that name.
Current label: 376 mg caffeine yield
The Supplement Facts panel lists one 19.7 g scoop and 21 servings. Caffeine comes from 340 mg caffeine anhydrous, 34 mg extended-release material yielding 25 mg caffeine, and 14 mg delayed-release material yielding 11 mg. The total is 376 mg caffeine, rather than the 388 mg weight of those three ingredients.
Other disclosed amounts include 6 g L-citrulline, 3.2 g beta-alanine, 2.5 g betaine anhydrous, 2 g L-tyrosine, 1 g agmatine sulfate and 500 mg VitaCholine choline bitartrate. The latter supplies the separately listed 200 mg choline.
An important extract-weight distinction
The label specifies 120 mg bitter orange extract standardized to at least 25% p-synephrine. That corresponds to at least 30 mg p-synephrine, not 120 mg pure synephrine. The product webpage’s shorthand does not preserve that distinction. Other entries include 100 mg ivy extract, 20 mg huperzia extract standardized to 1% huperzine A, 10 mg vincamine and 1 mg Alfabin rauwolscine material marked 90%.
Why tolerance alone is not enough
This is a multi-stimulant product. Being comfortable with coffee does not establish how you will respond to the full combination. NCCIH reports inconsistent performance findings and unresolved cardiovascular safety concerns for bitter-orange supplements. Reported serious events often involved multi-ingredient products, so causation is not established.
The 376 mg caffeine serving is close to the FDA’s general 400 mg daily reference for most adults. That number is not a personal target and does not certify combinations of stimulants as safe. Avoid additional caffeine or stimulant products, and have a clinician assess suitability if you take medicines or have a medical condition.
Before choosing a tub
Match the exact Supplement Facts, serving weight and warnings to the version you are buying. If you need caffeine-free training support, compare a separately labeled stimulant-free formula. Extreme branding and a larger stimulant load do not establish better training results, and this guide does not claim hands-on testing.
