pushxPWR Pump-Tart: Jess Whitman’s Stunning Stim-Free Pre-Workout Supplement

pushxPWR is the new brand from fitness coach and influencer Jess Whitman (@jesswhit_fit), who’s well-known for high-energy personality and overall good vibes on top of her fun and effective workouts. Her new product Pump-Tart is a stimulant-free pre-workout powder aimed at enhancing power output, better muscle endurance, greater muscle definition and cognitive enhancement – without the caffeine.

pushxPWR Pump-Tart!

pushxPWR Pump-Tart

pushxPWR is Jess Whitman’s new supplement brand, debuting with two supplements – one of which is Pump-Tart, a powerful and uniquely flavored stimulant-free pre workout supplement.

Looking at the tub, you’ll likely agree that Jess is targeting her female demographic, but don’t be fooled by that, guys — this is a pump supplement that can get even the biggest of bodybuilders pumped to the gills. The product delivers a powerhouse blend of L-Citrulline, Taurine, Betaine, L-Ornithine, and a clinically-studied dose of Nutrition21’s Nitrosigine.

An added bonus is the amazingly distinctive flavor — Pump-Tart was built to taste just like Strawberry Pop-Tarts! This adds a lot of fun to a workout routine and gives something to look forward to each day.

It’ll stack quite well with pushxPWR’s push-E pre workout supplement (which is well-built for Jess’s demographic at a lower stimulant profile), so we’ll have to cover that next. But for now, let’s dig into the Pump-Tart label:

pushxPWR Pump-Tart Ingredients

Not just a novelty beverage, Pump-Tart supplement delivers some serious pumps and performance-enhancing benefits. Each two scoop serving includes 6000mg of L-Citrulline, 2500mg Betaine Anhydrous, 1500mg Nitrosigine, 1500mg L-Ornithine Hydrochloride, 1000mg Taurine and 100mg of VasoDrive-AP. pushxPWR didn’t hold anything back on making Pump-Tart a top-shelf product and Jess’s meticulous attention to detail with this blend shows that she’s definitely on top of their lab game.

pushxPWR Pump Tart Label

The full pushxPWR Pump Tart Label — zoomed-in ingredients are below

With no caffeine nor stimulants, Pump-Tart avoids any extreme crashes in energy and is usable at any time of day that suits your workout schedule. People looking for an effective product to gain consistent strength and endurance improvements during their workouts should consider Pump-Tart and we’ll dive into each ingredient below with some insights.

  • L-Citrulline – 6000mg

    pushxPWR Pump-Tart Ingredients

    Jess’s demographic may be women, but even the biggest of bodybuilders will get huge performance and pumps with this formula!

    L-Citrulline has become one of the most reliable and most popular used nitric oxide boosters on the market today. Pump-Tart delivers an abundant 6000 milligrams providing a full clinical dose. This dynamic amino acid is needed in helping our bodies create more L-arginine, which in effect creates more nitric oxide (NO). Nitric oxide aids in the relaxation and expansion of our blood vessels, allowing for greater blood flow and delivery of oxygen to the body.[1,2] This effect (known as vasodilation) contributes to what weight lifters call “the pump.”

    In consequence, this provides the endurance and stamina we desire during exercise for those big pumps. In addition, our bodies receive more efficient nutrient delivery and reduced blood pressure giving us more sustainable energy, improved recovery and helping us avoid the dreaded “jitters.”[3-6]

    Most users know the greatness of L-citrulline at this point – the main idea here is nitric oxide pumps and it’s well-dosed – here it’s twice the clinically-tested dose for statistically significant nitric oxide improvements.

  • Betaine Anhydrous – 2500mg

    The role of Betaine (also known as trimethylglycine) as a muscle builder is similar to creatine, but adds a few different benefits. While creatine is well known for supplying phosphate, betaine is a methyl donor that doubles as an osmolyte, meaning it helps balance fluid levels across cells, keeping them quicker to recover[7,8] and preventing them from thermal shock.[9] Clinically-studied doses are 2500 milligrams per day for both muscle-building and weight loss in women,[8,35] and Pump-Tart delivers another serving of riches here.

    Betaine Fat Loss Women

    2.5 grams of betaine per day led to significant fat loss in women in eight weeks![35]

    In addition to the muscle growth benefits, many users confirm improved workout pumps with adequate water intake. This is due to its osmolyte function, improving water retention and maintaining the integrity of cells. Studies have also shown there may be elevation in nitric oxide.[10]

    Betaine has also shown to be an efficient fat burner, which will be useful to Jess’s dieting fans and followers. A 2019 systematic review of six studies with 195 participants found that betaine supplementation significantly reduced total body fat mass and body fat percentage.[11] In 2004, an athletic-based research team found that a six-week training program with 2500mg of betaine per day yielded a 3% reduction in body fat,[8] and another in 2018 had similar success.[35]

    All in all, the weight loss effect is a feature every Pump-Tart user should find useful in reaching their fitness goals — but we’re really here for that water-bourne pump.

  • Nitrosigine (Inositol-Stabilized Arginine Silicate) – 1500mg


    Move over L-arginine, Nitrosigine (inositol-stabilized arginine silicate) actually makes it work as originally desired!

    Pump-Tart continues to impress with another powerful and notable ingredient with Nitrosigine, created by the developers at Nutrition21.[12] pushxPWR didn’t hold back on the serving amount either — Pump-Tart delivers big with a 1500 milligram dose, the clinically-studied dose used in all of Nutrition21’s research that’s been shown to be comparable to 8 grams of citrulline malate.[13]

    Nitrosigine features a patented inositol-stabilized arginine silicate, and the beauty is in how it increases the bioavailability of L-arginine, allowing for more viable and potent nitric oxide boosting. Nitrosigine is rapidly becoming one of the industry’s most studied and sought after ingredients, with robust research coming out frequently.

    With the increased bioavailability of L-arginine, users get a more sustainable nitric oxide boost, giving superior results. Research has shown that blood arginine levels increase for six hours after use.[14,15] Analysis has proven that when arginine is used with citrulline, there’s a synergistic effect limiting arginase activity and preventing the breakdown of the arginine.[16-18] pumpxPWR clearly understands this significance and provides an applicable dosage with their Pump-Tart formula.

    Nitrosigine Nootropic

    Nitrosigine as a nootropic? Research shows vastly improved TMT scores, and the arginine nitric oxide pathway does work in the brain, so…

    A stimulant-free pump ingredient that provides cognitive enhancement

    In addition to giving you a heightened pump and improvement to your athletic performance, there’s an abundance of data to suggest that Nitrosigine delivers cognitive-boosting benefits as well.[19-22]

    Lengthy and laborious activities, such as intense athletic actions that are fast-paced and cognitively rigorous, can be mentally taxing. Research has affirmed that mental fatigue decreases athletes’ responsiveness and bodily movements, as well as sport-specific technical performance,[20] consequently proving the seriousness of cultivating a safe and reliable cognitive state during intense exercise. By upholding cognitive function and averting mental fatigue from strenuous exercise, athletes can go on focused and energized for prolonged periods.

    Key findings in a recent study on healthy individuals has also shown that Nitrosigine substantially improves cognitive function compared to those on a placebo.[21] Inositol, a core molecule in Nitrosigine, has also been shown to increase mental stamina, focus, and alertness.] Pump-Tart’s supplementation with Nitrosigine provides the additional leverage desired to get the most out of our workouts and give us a competitive advantage in any sport.

    While citrulline may be the largest-dosed ingredient, we consider Nitrosigine to be the star of the show in Pump-Tart.

  • L-Ornithine Hydrochloride – 1500mg

    Pump-Tart Supplement

    Jess’s branding game? On point.

    L-ornithine hydrochloride is an endurance-boosting amino acid that binds to ammonia and releases more citrulline in the process. L-orthinine is one of the three amino acids involved in the urea cycle (the other two are L-arginine and L-citrulline). The urea cycle is vitally important for converting highly toxic ammonia into urea and excreting it from the body.

    Studies show that L-ornithine is efficient at warding off fatigue.[23] With high intensity exercise, ammonia levels begin to rise, and this increase in ammonia immensely reduces muscle function.[24] Preventing this increase in ammonia drastically improves muscle performance.[25]

    Once again, pumpxPWR proves that they’ve done their due diligence in making Pump-Tart a high quality product – we don’t see ornithine taken advantage of enough. While most of us know of the efficacy of citrulline and Nitrosigine, L-ornithine deserves more attention and should be considered the most “underrated” ingredient in the formula — especially at this solid dosage.

  • Taurine – 1000mg

    pushxPWR Jess Whitman

    Progress without Restriction. That’s pushxPWR

    In Pump-Tart we get a mighty 1000 milligram serving of taurine, giving us a solid boost of endurance and cognitive benefits. In a 2018 meta-analysis, researchers observed ten different studies and analyzed taurine’s effects on stamina.[26] The researchers concluded that when doses of taurine ranged from 1 to 6 grams per day (in single doses and for up to 2 weeks) across numerous subjects, it significantly increased overall endurance performance.

    Taurine is also an osmolyte, giving more support to our cells and balancing water in our bodies.[27] This makes taurine a perfect pairing with betaine as it further boosts muscle contraction biochemistry while cutting down oxidative stress and even enhancing fat digestion.[28-31] Hydration is critical for maximum physical performance and pushxPWR once again comes through.

    Cognitively, taurine benefits focus by protecting the brain against inflammation and stress.[29] It also upregulates GABA receptors, and boosts activity in neuronal synapses.[26] Taurine’s assistance here helps with the reproduction of new brain cells, and has been identified as an effective advancement in brain development.[32]

    Taurine has many awesome benefits that go well beyond athleticism, and we love seeing it in the Pump-Tart formula.

  • Low-Molecular Weight BioActive Peptides (as VasoDrive-AP) – 100mg

    Nitrosigine vs. Arginine HCl

    One last Nitrosigine immage — with Arginine HCl, plasma arginine drops off a cliff. With Nitrosigine (ASI), it keeps on ticking. The uptick at hour 4 seems to be due to arginase inhibition!

    VasoDrive-AP is a unique ingredient that promotes better pump performance by delivering greater blood flow and vasodilation, while simultaneously reducing blood pressure.[33] Developed by Noyanturi, VasoDrive-AP is a proprietary ingrredient produced through a patented fermentation and enzymatic process. This unique procedure produces two lactotripeptides, Valyl-Prolyl-Proline (VPP) and Isoleucyl-Prolyl-Proline(IPP), which have the impressive outcome of hindering angiotensin converting enzyme (ACE).[33]

    For those that are unaware, ACE causes vasoconstriction, which reduces blood flow, decreases nutrient and oxygen delivery, and ultimately decreases your performance[34] — the exact opposite of what you want while training! VasoDrive-AP prohibits this process providing a clearer pathway to achieve greater pumps and better physical performance.

    An ingredient gaining in popularity which pays huge dividends in the gym and we love to see it in this formula. As a final note, VasoDrive-AP is made from hydrolyzed milk casein, so people with severe dairy allergies should be aware of this ingredient – although we’re confident that it’s primarily just the tripeptides and not any milk derivatives inside.

Flavors Available

pushxPWR Pump Tart

As mentioned in the intro, Pump-Tart launched with a Strawberry flavor modeled after the industry’s favorite toaster pastry! While it’s tough to get that wheat flavor in, the word on the street is that Jess killed it with this flavor — it’s a fun, sweet flavor experience.

pushxPWR = Progress without Restriction

Pump-Tart is one of the first two supplements from pushxPWR — the other being the push-E stim-based pre-workout that you can stack this with. However, given the team’s initial success we highly doubt it will be their last!

Jess and the team deserve a round of applause for bringing a product to market that’s a proper formula for their mostly-female client base, but also suitable for any hardcore gym monster! It’s refreshing to see a young brand coming into the industry with authentic creativity and delivering research proven results.

Jess has a level of enthusiasm that is contagious and signals pushxPWR will be a rising force for many years to come. If Pump-Tart is any indication of the level of thought and diligent analysis put into pushxPWR products, this is a brand that is just getting started and we’re excited to see what else they’re cooking up!

Next up? The push-E pre-workout supplement!
