NutraBio Labs Leg Day Intra Workout Fuel (20 Servings)

If you spend your gym time texting on the squat rack, LEG DAY isn't for you. If the highlight of your workout was bragging about shorting Game Stop, take a pass. But if the clanging of iron and grunting of all-out effort is your call to action. If you make every workout life altering, decimate every set, annihilate every rep, then LEG DAY is your liberator.

NutraBio Labs Leg Day is a supreme intra workout formula with the following key ingredients:

Bioenergy Ribose

Bioenergy Ribose is a novel 5-carbon carbohydrate that regulates the body's natural energy production. Ribose is present in every cell of the body and serves as the backbone of the ATP molecule. This premium ergogenic is ideal for dedicated athletes and weekend warriors to help improve performance, boost stamina, delay the onset of fatigue, reduce muscle soreness, and promote stable energy levels.*

L-Dopa

L-Dopa is an amino acid that is naturally produced by the body, and it's also readily found in Mucuna pruriens (velvet bean). It serves as the direct precursor to dopamine, a neurotransmitter involved in mood, motivation, focus, and motor control. Exhaustive exercise is known to deplete dopamine levels which can lead to reductions in performance and increased feelings of fatigue. Supplementing with L-Dopa may help attenuate the onset of fatigue, allowing athletes to continue to train at a high level for longer, ultimately accomplishing more work and making greater gains.*

elevATP

elevATP contains a patented blend of plant bio-inorganic trace minerals and polyphenols from ancient peat and apple extracts that has been shown to increase intracellular ATP levels in whole blood and muscle. Studies in healthy, resistance-trained athletes note that supplementation with elevATP can improve strength, power, and performance.

NeuroFactor

NeuroFactor is an all-natural, patented extract of whole fruit from the Coffea arabica plant that contains a unique profile of polyphenols that have been shown to stimulate the production of Brain-Derived Neurotrophic Factor (BDNF) -- a neuroprotein that plays a key role in the development, maintenance, and repair of neurons as well as offers protection against neuro-degeneration. BDNF is also known to impact learning, memory, and higher thinking, which may help athletes stay “locked in” for longer during intense training sessions.*

Senactiv

Senactiv is a 100% natural ingredient containing a unique blend of panax notoginseng and rosa roxburghii that is backed by 6 human clinical studies. Specifically, supplementation with Senactiv is noted to enhance muscle energy by boosting citrate synthase activity by 47%. Citrate synthase is an important enzyme that is responsible for producing more ATP. And, Senactiv is also known to support muscle preservation and regeneration via the removal of old cells and reducing inflammation.*

Cluster Dextrin

There's no other way to say it -- carbohydrates fuel performance. They are the body's preferred source of energy during intense physical activity...like the kind you'll be doing on leg day.*

Cluster Dextrin (highly-branched cyclic dextrin) is a premium-grade high-performance carbohydrate that helps fuel the demands of hard training athletes.*

Cluster Dextrin has a high molecular weight and ultra-low osmolality, allowing it to rapidly navigate the GI tract and then be efficiently transported to muscle cells. This primetime performance carb is also low glycemic so it won't spike blood sugars, but will provide a smooth, sustained release of energy to power you through your entire workouts.*

Research also indicates that supplementing with Cluster Dextrin may improve time to exhaustion and reduce stress hormone response and lower urinary cytokine levels to intense exercise.*

Growth Factor BCAA/EAA

The body uses around 20 amino acids to construct protein, including the kind that make up skeletal muscle tissue.*

Of those 20-odd amino acids, nine of them must be obtained through the diet as the body cannot make them. These are called essential amino acids (EAAs).

Without sufficient amounts of these essential amino acids, performance, recovery, muscle growth, and ultimately health is compromised.*

LEG DAY delivers a robust 7.6 grams of essential amino acids (including 2.5 grams of leucine) to stimulate protein synthesis, combat muscle breakdown, and support muscle recovery and repair.*

L-Ornithine

Ornithine is an amino acid that is naturally produced by the body and plays a key role in the urea cycle, which takes ammonia, a waste product of amino acid breakdown, and converts it to urea.*

Supplementation with ornithine supports ammonia buffering, which may help delay the onset of fatigue, increase anaerobic performance, and promoted faster recovery.*

Electrolyte & Hydration Optimizer

Proper hydration is vital to optimal performance.*

In fact as little as a 2% decrease in hydration is known to reduce performance and increase perception of fatigue, and it may also increase risk of injury.*

Intense exercise causes intense sweating, and when you sweat, you're not only losing water, but valuable electrolytes too. These same electrolytes are responsible for optimal muscle function (strength, power, etc.).*

Failing to replace these depleted electrolytes can lead to premature faituge, performance dropoff, difficulty concentration, and cramping.*

LEG DAY includes a comprehensive array of essential electrolytes as well as a full 1,000mg of Taurine -- an amino acid that functions as an osmolyte, which encourages muscle cells to absorb more fluid, increasing muscle fullness and hydration while combating the onset of fatigue.*

AstraGin

AstraGin is a novel complex of highly purified and fractionated Panax notoginseng and Astragalus membranaceus shown in 16 in-vitro and eight in-vivo studies to increase bioavailability and absorption of several key nutrients, including the uptake of numerous amino acids (e.g. leucine 58% increase).*

AstraGin may also support better muscle recovery and growth following training as studies on ginsenosides (one of the active components in AstraGin) note that it activates the mTOR signal pathway by regulating upstream kinases in muscle cells.*


Suggested Use: For intra-workout, mix 1-2 scoops (1-2 servings) with 32-64 ounces of cold water. Drink approximately 1/3 of mix 20 minutes prior to intense training, then sip the remainder throughout your training session. As a peri-workout, use pre, intra or post training to enhance endurance and recovery

The Chuck Norris of Dog Toys
Color: Orange
If dog toys were superheroes, the Nevperish K9 Training Ball would be Batman—indestructible, effective, and always ready to save the day. This thing flies. I’m not saying I could take out a rogue squirrel in a single throw, but… let’s just say those little guys know to keep their distance now. My 100lb German Shepherd, who we affectionately call "The Toy Terminator," has destroyed every squeaky, chewy, or bouncy thing in her path. But this? This glorious, rope-swinging masterpiece? She’s met her match. It’s like her teeth have signed a peace treaty with this toy. Speaking of flying, if you have neighbors with a backyard that’s less than a football field away, be prepared for some fence-hopping cardio. I’ve had more awkward encounters with my neighbors than I care to admit. Thankfully, my shepherd has learned the art of the double hop—over their fence and back—like some four-legged ninja gymnast. Bonus: great entertainment for the neighbors. This toy isn’t just a ball on a rope; it’s a lifestyle. Open fields? Perfect. Tug-of-war? Immaculate. Backyard fetch? A cinematic masterpiece. It’s basically the Swiss Army knife of dog toys, minus the danger of accidental stabbing. Pro tip: Don’t underestimate how far this thing can go. My first throw ended with the ball in orbit—or maybe it just bounced off a satellite. Either way, my dog was thrilled, and now I need an arm warm-up routine before playtime. So, if you want a toy that’ll outlast your dog’s dental fury and make fetch sessions the stuff of legend, this is it. 10/10, would absolutely get weird looks from neighbors again.

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.

Great for smaller dogs
Size: Small
These two balls are perfect for the smaller mouthed dog that loves to play fetch. These balls are not only super durable (lots of teeth biting), but float in the baby pool we use for our miniature dachshunds. The value here is much better than you’d find anywhere else. The noise, if bitten hard enough, was “low” at best. Easy to spot/find if overthrown. Will definitely buy again once these are in bad repair; so far, so good-love these for my fur babies!

My dogs favorite balls
Size: Medium
These are great for my dog who always has to have a ball in her mouth. Not too hard so I don't have to worry about her teeth. They last for ever. They do lose their shape a little over time (like I said, she always has a ball in her mouth) they become a little oval in shape. They still bounce, she still chases it and she still chews on it so I don't think she notices or cares. I've gotten her a bag full of these over time and I have only seen one that she chewed a chunk out.
