Efectiv Legacy Pre-Workout, 400mg Caffeine and 8g Pure L-Citrulline Per Scoop
Efectiv Nutrition Legacy is a high-stimulant pre-workout built for experienced users who want a real step up from standard formulas. Each 20g scoop delivers a total stimulant load of around 1200mg, headlined by 400mg of caffeine from a dual-source blend (caffeine anhydrous for a fast onset plus Infinergy di-caffeine malate for a longer tail).
Beyond the stimulants, Legacy provides 8g of pure L-citrulline per scoop for blood flow and pump support. Many pre-workouts list citrulline malate (a 2:1 blend with malic acid), so only two-thirds of the listed dose is actual citrulline. Legacy uses the pure form, so the full 8g goes toward nitric oxide production.
The formula includes six trademarked, research-backed ingredients: AstraGin for nutrient absorption, BioPerine for bioavailability, Infinergy for sustained caffeine release, S7 (a plant blend studied for nitric oxide), VitaCholine for focus and Zynamite (Mangifera indica extract) for mental energy. Every dose is printed on the label, with no proprietary blends.
The 390g tub provides 20 full 20g servings. Legacy is not a daily pre-workout; it is built for the one or two hardest sessions per week. Start with half a scoop to assess tolerance and avoid taking within six hours of sleep.
