Stimulant-free pre-workout to train anytime during the day
Evostamina from SportSeries is a flavored dietary supplement made with mineral amino acids and plant extracts, with sweeteners.
Designed as a stimulant-free pre-workout for intense training blocks, especially when you train late and don’t want to rely on caffeine. Evostamina’s approach is clear: instead of “pumping you up” with stimulants, it bets on a balanced formula that tackles other aspects independent of caffeine, with a core composition based on bicarbonates, standardized extracts (nitrates and polyphenols), and amino acids commonly found in high-end pre-workouts.
If you like training hard but want a stimulant-free option, here’s your “black potion”.
The “Black Potion”: a unique HSN experience
Evostamina is known as “the black potion” because of the dark color the mix takes on when prepared. It’s not just an aesthetic nod: it’s a way to turn the pre-workout into a habit, something that matters more day to day than it seems, since the absence of stimulants depends on taking advantage of the nutritional benefits of supplementing daily (not occasional) intake of bicarbonates and amino acids.
Evostamina is also a delicious pre-workout: We’ve perfectly balanced the aroma work to develop incredible flavors that fit deliciously with the type of product it is, along with a balanced sweetness and acidity so you’ll enjoy Evostamina as a pre-workout you’ll want to repeat day after day.
The formula’s core: bicarbonates, nitrates, and polyphenols
If your goal is a stimulant-free pre-workout, the real value lies in the blend’s architecture. In Evostamina, the core is built with three components that together set it apart from other stimulant-free pre-workouts designed just for marketing.
Sodium and potassium bicarbonate: Evostamina’s “buffer” component
Bicarbonates are a key pillar of this formula. Based on research like that from the International Olympic Committee positioning them as a buffer athletes should consider, without stimulant load, being compounds with a high level of evidence.
Standardized beetroot extract in nitrates
Beetroot has become a classic in modern pre-workouts. The difference is in how it’s formulated: In Evostamina, we’ve used a high-concentration extract (25:1) of Beta vulgaris root with standardized nitrate content, which ensures consistency by guaranteeing a reliable amount of its nutrients relevant for athletes.
Vinitrox™: grape and apple polyphenols with a leading patent
To complete Evostamina’s formula, we included a significant dose of polyphenols from concentrated grape (Vitis vinifera) and apple (Malus pumila) extracts under the brand Vinitrox™. A “top” patent that strengthens Evostamina’s composition as a complete stimulant-free pre-workout, no caffeine needed.
An amino acid stack with citrulline, beta-alanine, and taurine
Evostamina doesn’t just focus on bicarbonates or nitrates. Beyond the formula’s core, we included a set of amino acids specifically selected for their synergistic traits: beta-alanine with bicarbonates and citrulline with nitrates.
L-citrulline from plant-based fermentation: 100% plant-based
The fact that L-citrulline comes from a plant-based fermentation process is a formulation detail that’s “very us.” Instead of using cheap amino acid sources or synthetic alternatives, we prefer to use quality plant-based raw materials.
Beta-alanine and taurine: strategic doses in the formula
Beta-alanine and taurine are classic amino acids in pre-workout formulas. In Evostamina, their role is to complete the blend and leverage the synergistic characteristics they share with the formula’s core compounds to round it out without stimulants.
What else does Evostamina bring you?
We can’t overlook another key element in Evostamina’s formula: creatine monohydrate:
- Creatine improves sports performance in successive bouts of brief, high-intensity exercise. The beneficial effect is achieved with a daily intake of 3 g of creatine. Intended for adults performing high-intensity exercise.
- Daily creatine intake may enhance the effect of resistance training on muscle strength in adults over 55 years old. Targeted at adults over 55 who regularly do resistance training; the beneficial effect is obtained with a daily intake of 3 g of creatine combined with resistance training, allowing an increase in workload over time and should be performed at least three times per week for several weeks, with an intensity of at least 65%-75% of one repetition maximum load.
As you can see: Evostamina isn’t just a simple stimulant-free pre-workout, but a complete proposal thanks to its formula design and user experience.
How to use it in your routine: don’t limit it to training days
If you train endurance (or face a tough block) and don’t want to use caffeine or stimulant formulas, Evostamina is perfect. Keep in mind that the formula’s benefits depend on daily use, not occasional, like other pre-workouts. Evostamina won’t work properly if you only use it one or two days a week.
For training in the late afternoon or evening or if you’re sensitive to caffeine
A great practical point of Evostamina is clear: it doesn’t rely on stimulants. That makes it a handy option for those who train late in the day, those who already consume coffee and don’t want to pile on more stimulants, or those who simply prefer a pre-workout without jittery feelings because they’re sensitive to caffeine.
Comparison with other HSN pre-workouts: choose based on your preference
At HSN, Evostamina is one of the best pre-workout options, but you have many others.
If you want stimulants: Evordx 2.0
Evordx 2.0 is the classic choice for those looking for a more pronounced “push” experience and don’t mind using caffeine.
If you want another stimulant-free alternative: Evopump powder
Evopump powder is another stimulant-free alternative with a different focus than Evostamina: it stands out for its high nitrate content. If your priority is a stimulant-free pre-workout more focused on strength than endurance sports, it’s your clearest option.
Common questions before choosing Evostamina
Is it a pre-workout suitable for night training?
Yes. It’s designed precisely for those who train late and don’t want to rely on stimulants. If your priority is to perform well while protecting your rest routine, Evostamina is perfect for you.
Why does Evostamina produce bubbles?
Because of the effervescence from the contact between bicarbonates and acidic compounds in the formula. You can prepare it directly in a glass; be careful if you mix it by shaking in a shaker, so it doesn’t build pressure from bubble production. It doesn’t need long mixing or intense shaking.
Why does the mix turn so dark?
Because of Vinitrox™ that dyes the liquid and gives it that characteristic “black potion” look.
Is it for me if I don’t do endurance?
Yes, as long as you’re looking for a stimulant-free pre-workout with a complete formula. It works very well for intense training in general, especially if you avoid caffeine or train late in the day.
Why choose Evostamina: formulation quality above all
Evostamina stands out for a simple but uncommon idea: not trying to “replace” caffeine, but building a real alternative with quality ingredients, standardized extracts, and a specific amino acid selection that, together with studied doses, provides real value as a stimulant-free formula.
