Efectiv Legacy Pre-Workout, 400mg Caffeine, 8g Citrulline and Six Trademarked Ingredients
Efectiv Nutrition Legacy is a high-stimulant pre-workout built for experienced users who want a noticeable step up from standard formulas. The total stimulant load per serving is approximately 1200mg, headlined by 345mg of caffeine anhydrous and 52mg of Infinergy (di-caffeine malate), which provides a dual-phase energy profile. The anhydrous caffeine hits quickly while the di-caffeine malate extends the effect over a longer window.
Beyond the stimulant profile, Legacy includes 8g of pure L-citrulline for pump and blood flow support. This is worth noting because many pre-workouts list citrulline malate (a 2:1 blend of citrulline and malic acid), which means 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 also includes six trademarked, research-backed ingredients: AstraGin for nutrient absorption, BioPerine (black pepper extract) for bioavailability, Infinergy for sustained caffeine release, S7 (a plant-based blend shown to increase nitric oxide by up to 230% in research), VitaCholine for focus support and Zynamite (Mangifera indica extract) for mental energy. Every ingredient dose is printed on the label with no proprietary blends.
A 390g tub provides 20 full servings at a 20g scoop size. This is not a daily-use pre-workout. It is designed for the one or two hardest sessions per week where you want maximum output. Start with half a scoop to assess tolerance if you have not used a high-stim formula before. Avoid taking within 6 hours of sleep.
