About the Product
Marvelous Nutrition's INFECTED is the flagship non-stimulant pre-workout (non-stimulant) from the Marvelous Originals portfolio, formulated with ultra-pharmaceutical grade ingredients for maximum pump, muscle building, and caffeine-free energy. The absence of stimulants (no caffeine, no synephrine, no guarana) makes it suitable for nighttime workouts, for caffeine-sensitive athletes, or for use in parallel with a stimulant pre-workout without overloading the central nervous system. The most innovative ingredient in the formula is Zynamite® (patented mango leaf extract, Mangifera indica), which provides caffeine-free energy and focus via a completely different mechanism. The formula also includes L-Citrulline D-Malate, Arginine AKG, creatine monohydrate, betaine HCl, beta-alanine, and beetroot extract (15% nitrates) for maximum pump and performance. Flavors: Fruit Punch and Watermelon. Vegan.
Benefits
The non-stimulant pre-workout: the solution for nighttime workouts, caffeine sensitivity, and stacking:
INFECTED fills a specific niche in Marvelous's range: the athlete who wants the pump, vasodilation, and performance benefits of a complete pre-workout but without the caffeine that would interfere with sleep (workouts after 6 PM) or without adding more stimulants to their day (for those who have already consumed caffeine in coffee or a morning pre-workout). In addition to standalone use, INFECTED can be stacked with Experiment or Power M.F for higher intensity sessions, where INFECTED adds the pump component and the stimulants from the other pre-workout add the energy — without duplicating conflicting ingredients.
Zynamite® (mango leaf extract, Mangifera indica): caffeine-free energy and focus:
Zynamite® is a patented ingredient from Nektium (a Spanish botanical ingredients company) extracted from the leaves of Mangifera indica (mango tree) and standardized for mangiferin (the main C-glucosidic xanthone in mango leaf). Mangiferin has multiple mechanisms of action relevant to athletic performance without conventional adrenergic stimulation: it inhibits phosphodiesterase (PDE) — the same mechanism as caffeine, but with greater selectivity for PDE-4 and PDE-5 subtypes vs. PDE-1 (which may explain less impact on heart rate and anxiety compared to caffeine); it has antioxidant and anti-inflammatory properties (inhibition of NF-κB and free radical scavenging); and it has a neuroprotective effect (modulation of dopaminergic and serotonergic transmission). The clinical trial by Gelabert-Rebato et al. (2019), published in Nutrients, documented that Zynamite® improved performance in high-intensity exercise (Wingate sprint and countermovement jump) and muscle recovery markers compared to placebo, with a favorable side effect profile and without the typical cardiovascular stimulant effects of caffeine.
Beetroot extract 15% nitrates: vasodilation via endogenous NO pathway independent of arginine:
Beetroot extract (Beta vulgaris) standardized to 15% nitrates (NO₃⁻) adds a completely different and complementary nitric oxide production pathway to that of citrulline/arginine. Dietary nitrates are converted to nitrites (NO₂⁻) by oral cavity bacteria and salivary glands, and nitrites are subsequently reduced to NO (nitric oxide) by various tissue reductases (including deoxyhemoglobin and xanthine oxidase), especially under conditions of low pH and low O₂ — that is, precisely the conditions created in muscles during high-intensity exercise. This NOS-independent (nitric oxide synthase) NO production pathway works even when the arginine-NOS pathway is saturated or inhibited, making beetroot nitrates synergistic (and not merely additive) with the citrulline/arginine in the formula. The meta-analysis by Siervo et al. (2013) documented that supplementation with beetroot juice (rich in nitrates) significantly reduced systolic blood pressure and improved O₂ efficiency during exercise.
L-Citrulline D-Malate + L-Arginine AKG: the dual vasodilator stack (shared with Experiment):
As described in Experiment, the combination of L-Citrulline D-Malate 2:1 and L-Arginine AKG provides rapid onset (arginine AKG) + prolonged sustenance (citrulline malate) of NO production and muscle pump. The addition of beetroot extract with nitrates adds a third NO pathway independent of the previous two, creating a trilogy of NO sources with distinct and complementary mechanisms.
Creatine monohydrate + Beta-alanine + Betaine HCl: the muscle performance stack:
INFECTED includes the three muscle performance compounds with the most clinical evidence — creatine (PCr resynthesis), beta-alanine (H⁺ buffering via carnosine), and betaine (methyl group donor, support for endogenous creatine synthesis, and osmoprotector) — in a non-stimulant pre-workout, which is relatively uncommon in the market where many non-stim pre-workouts only focus on pump and omit muscle performance components.
Complete Electrolytes + Vitamins B6, D3, B12: integrated metabolic support:
Like Savior and Maze, INFECTED includes electrolytes (Na, K, Mg, Ca) and vitamins B6, D3, and B12 for complete metabolic support, making it a nutritionally complete pre-workout instead of just a pump and performance stack.
Uses
Recommended dose: Mix 1 serving with 250 to 300 ml of cold water, 15 to 30 minutes before training. As it contains no stimulants, it can be consumed at any time of day, including during nighttime workouts, without impacting sleep. For stacking with a stimulant pre-workout, mix INFECTED with half a serving of Experiment or Power M.F to simultaneously cover pump (INFECTED) and stimulant energy (Experiment/Power M.F).
