Read before you buy. — Mostly Legit

  • "Caffeine + L-theanine reduces jitters"

    Clinical trials confirm this combo improves focus and reduces anxiety compared to caffeine alone at 200mg doses.

    Examine.com L-theanine + caffeine research summary
  • "Proprietary blend hides ingredient doses"

    Only caffeine (220mg) is disclosed. Beta-alanine, ginseng, rhodiola, L-tyrosine doses are hidden, making efficacy verification impossible.

  • "Beta-alanine extends fatigue resistance"

    Clinical studies use 4.8-12g daily for weeks. Pre-workout single doses are typically 2-3g, likely too low for proven benefit.

  • "Rhodiola enhances endurance"

    Reduces fatigue perception, but lab testing shows product quality varies 0-3x label claims—no third-party testing disclosed.

Consumer advice

If you're sensitive to caffeine jitters, this is a solid choice because L-theanine genuinely smooths out caffeine's edge. However, verify you actually need a pre-workout before buying—coffee with a scoop of whey protein is 90% as effective for 1/10 the cost. Check the supplement facts label (visible in product images) to confirm the proprietary blend doesn't hide underdosed actives. Subscribe for 15% off if you plan to use it regularly, but cancel immediately if you don't—subscription traps are common in this category.
