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.

Frequently Asked Questions

Why does Legacy use pure L-citrulline instead of citrulline malate?

Citrulline malate is a 2:1 blend of L-citrulline and malic acid, so a 6g dose only provides about 4g of actual citrulline. Legacy uses 8g of pure L-citrulline per scoop, so the entire dose contributes directly to nitric oxide production and blood flow during training. That gives Legacy a higher effective pump dose than many formulas listing similar or larger amounts of citrulline malate.

How does Legacy compare to Applied Nutrition ABE?

Legacy is a noticeably stronger formula. ABE contains roughly 250mg caffeine, 4g citrulline malate and 2g beta-alanine per serve. Legacy contains 400mg dual-source caffeine, 8g pure L-citrulline, 3.2g beta-alanine and a total stimulant load of around 1200mg. ABE works well as a regular training-day pre-workout. Legacy is built for experienced users who want maximum support on their hardest sessions.

What is S7 and what does it do in the Legacy formula?

S7 is a plant-based blend of green coffee bean, green tea, turmeric, tart cherry, blueberry, broccoli and kale included in the Legacy formula. Research on S7 has reported increases in the body's own nitric oxide production. In Legacy, higher nitric oxide levels alongside 8g pure L-citrulline support blood flow to working muscles, contributing to pumps and endurance during training.
