25g Cluster Dextrin®, full EAAs, ATP and hydration support

NutraBio Leg Day isn't your basic amino drink or a standard pre-workout. It's a stim-free intra-workout built for one thing: tough leg sessions that chew up glycogen, mess with hydration, and wear you down mentally. The plan here is straightforward. First, hit you with quick but easy-on-the-gut carbs from 25g Cluster Dextrin®—that's highly branched cyclic dextrin, a fancy carb that digests fast. Second, deliver a complete essential amino acid setup led by 2.5g leucine and a 2:1:1 BCAA ratio to help recovery while you're training. Third, back up hydration and muscle function with sodium, potassium, phosphorus, magnesium, taurine, and coconut water powder. Last, throw in non-stim boosters for ATP production, faster recovery, and mental drive.

The foundation is solid. 25g Cluster Dextrin® is a dose that actually helps in long, tough workouts. This carb clears your stomach quick and gives steady fuel, so you avoid that bloated feel from cheaper options and get real energy when reps pile up. You'll notice steadier power and less of that mid-workout crash on heavy leg days.

The aminos beat most 'BCAA' drinks because it's not just leucine hype. 2.5g leucine hits the low end of what's shown to flip on mTOR and start muscle protein synthesis. 1.25g isoleucine and 1.25g valine round out the 2:1:1 BCAA setup, with isoleucine helping muscles grab glucose and valine fighting off brain fatigue by blocking tryptophan. Then lysine, threonine, histidine, phenylalanine, methionine, and tryptophan make it a full EAA deal, not some limited BCAA-only thing.

Taurine at 2g is an excellent inclusion. Taurine supports cell

Key Highlights

• 25g Cluster Dextrin® — a real intra-workout carb hit for serious training, not just for show. This highly branched cyclic dextrin empties from your stomach fast and delivers steady fuel, giving you workout energy without the heavy, sloshy vibe from cheaper carbs.
• 7.6g EAA matrix with 2.5g leucine — enough leucine to touch the low end of what's researched for kicking off mTOR and muscle building, while the other essential aminos give what leucine-only stuff misses. So this actually helps trigger real muscle protein synthesis, not just fake it with a BCAA sprinkle.
• 2:1:1 BCAA ratio at 5g total — 2.5g leucine, 1.25g isoleucine, and 1.25g valine. Leucine sparks the muscle-growth signal, isoleucine aids muscle glucose pull-in, and valine helps manage that brain fog during long hauls.
• 2,000mg taurine — a strong dose for cell hydration, balance, and muscle work. In real terms, it makes workouts feel fuller and steadier, especially with carbs and electrolytes on sweaty leg days.
• 150mg elevATP® — the exact dose from human studies on boosting your own ATP, leg strength, and power. One of the top non-stim boosters for guys wanting more output without extra caffeine.
• 50mg Senactiv® — dosed right at the research level for recovery, glycogen refill, and muscle repair signals. Smart add that fits the goal: not just getting through the workout, but bouncing back quicker.
• 100mg NeuroFactor® — the studied dose of this coffee fruit extract that boosts BDNF in people. Not a caffeine buzz; it's here to keep your mind sharp and focused when tiredness tries to pull you away.
• 150mg L-DOPA from Mucuna pruriens — a dopamine booster that sets this apart from basic carb-amino mixes. Not a huge dose alone, but it adds a nice motivation kick and teams up well with NeuroFactor® for leg-day performance.

Who Is This For?

• High-volume leg guys doing 60-90 minutes loaded, who feel glycogen tank mid-way. 25g Cluster Dextrin® and full electrolytes tackle that, holding output when water and pre-stims fall short.
• Bodybuilders in growth phases wanting to keep performance across compounds and isolations without more caffeine. EAA with 2.5g leucine, taurine, Senactiv®, elevATP® boost endurance, density, and recovery mid-gym.
• Evening trainers needing support without caffeine messing sleep. Stim-free setup gives carb fuel, ATP, hydration, and brain stuff like NeuroFactor® minus the long caffeine hangover.
• Powerbuilders chasing rep quality and session length on squats and hinges. Cluster Dextrin® holds capacity, electrolytes, taurine, aminos support contraction, balance, and less fade from first to last set.
• Cutters holding muscle while training hard. 7.6g aminos and 25g intra carbs back performance and retention when calories low would otherwise kill output and bounce-back.
• Cross-trainers mixing lifts and conditioning with leg focus. Carb-electrolyte-amino build suits better than pump or stim pre that amps but skips real fuel.

How to Use

Mix 1 scoop in 12-16 oz cold water, start sipping 10-15 minutes before, and keep at it during. That setup works because benefits come from steady carbs, hydration, and aminos mid-session, not a pre-peak. If new to intra carbs or have a touchy stomach, try half first, then full on longer days. Shaker's best for mixing, with 25g carbs and branded actives. Fine with a light pre-meal, but skip big food right before or you slow the fast-carb point. For caffeine, do it separate in a mild pre 20-30 minutes ahead; treat this as your intra layer, not stim hub. Stacks well with daily creatine and post protein. No cycling needed, no stim load. Store sealed, cool and dry—carb powders grab moisture easy.

What to Expect

First 0-10 minutes: it drinks like a true intra, not a thick shake. No stim kick; it's smooth, with hydration and gut ease hitting first since Cluster Dextrin® goes down better than cheap carbs. 10-30 minutes: as sets start, things feel steadier, less empty—big if you crash early on legs. 30-60 minutes: here's where it shines, carbs, taurine, electrolytes holding output while NeuroFactor®, Mucuna, and elevATP® keep drive and power. 60-90 minutes: instead of big drop, focus and capacity fade slower. Days 1-7: best on intra energy and hydration. Weeks 2-4: consistent use shows bigger gains in training quality and recovery from elevATP®, Senactiv®, and reliable fueling.
