Gorilla Mode Nitric Upgraded Stimulant Free Pre-Workout – Best Tasting and Most Effective Stimulant Free Pre-Workout/Massive Pumps · Vasodilation · Power / 804 Grams (Blue Raspberry)
- 10,000 MG PURE L-CITRULLINE - Many pre-workouts fall short of including the maximum effective dosage of PURE L-Citrulline, often artificially inflating their labels with Malic Acid by using Citrulline Malate. In reality, this means you’re only getting 1/2 to 2/3 as much L-Citrulline as the label implies. L-Citrulline is the most effective supplement to boost nitric oxide (NO) in the body – enhancing pumps, endurance, and recovery time.
- 5000 MG CREATINE MONOHYDRATE, 4000 MG HYDROPRIME, 4000 MG BETAINE ANHYDROUS, 3000 MG TAURINE - 8 combined grams of Hydroprime and Betaine work in synergy to supersaturate the muscle and induce a state of hyper-hydration for massive pumps, endurance and power. Lastly, we included a big dosage of Taurine, which enhances performance by improving muscle contraction, reducing oxidative stress, and promoting cellular hydration.
- 1500 MG SODIUM NITRATE AS NO3-T, 1000 MG AGMATINE SULFATE, 508 MG VASODRIVE-AP - These ingredients work synergistically to maximize nitric oxide production to improve pumps and performance. Agmatine increases eNOS, which, with L-Citrulline, covers the Arginine–eNOS–nitric oxide (NO). The nitrate–nitrite–nitric oxide (NO) pathway offers a high dose of nitrates. VasoDrive-AP tackles vasodilation from another angle via the inhibition of ACE, increasing oxygen and nutrient-carrying capacity.
- MIXES EFFORTLESSLY AND TASTES INCREDIBLE - Pre-workout ingredients are tricky to flavor, but even with 40 grams of active ingredients in Gorilla Mode Nitric, we nailed both the taste and mixability. We carefully selected ingredients like HydroPrime Glycerol, which mixes effortlessly to ensure every sip is as smooth and delicious as it is effective. The result? A formula that delivers massive pumps and peak performance without the synthetic aftertaste, chalkiness, or grit.
- 32,000+ MG TOTAL NITRIC OXIDE PRECURSORS, PLASMA EXPANDERS AND VOLUMIZING AGENTS - Loaded formula designed to comprehensively cover every worthwhile vector that supports skin-splitting muscular fullness, vasodilation, and pumps.
No. 7
Gorilla Mode Nitric Upgraded Stimulant Free Pre-Workout – Best Tasting and Most Effective Stimulant Free Pre-Workout/Massive Pumps · Vasodilation · Power / 808 Grams (Sour Gummy Worms)
- 32,000+ MG OF TOTAL HIGH IMPACT INGREDIENTS - Introducing Gorilla Mode Nitric, our turnkey stimulant-free pump pre-workout. Stacked with 32,478 mg of nitric oxide precursors, plasma expanders, electrolytes, and volumizing agents. Gorilla Mode Nitric powder pushes the limits of what a non-hormonal pre-workout can achieve, all while fitting into a regular container (any more, and we’d need a protein-sized tub to hold it all).
- 10,000 MG PURE L-CITRULLINE - Many pre-workouts fall short of including the maximum effective dose of PURE L-Citrulline, often artificially inflating their labels with Malic Acid by using Citrulline Malate. In reality, this means you’re only getting 1/2 to 2/3 as much L-Citrulline as the label implies. L-Citrulline is the most effective supplement to boost nitric oxide (NO) in the body – enhancing pumps, endurance, and recovery time.
- 5000 MG CREATINE MONOHYDRATE, 4000 MG HYDROPRIME, 4000 MG BETAINE ANHYDROUS, 3000 MG TAURINE & ELECTROLYTES - Supersaturates muscle cells with fluid, supporting hydration and volumization that drive massive pumps, endurance, and power. Creatine reliably improves strength, power output, and muscle size. Complementary osmolytes and electrolytes enhance cellular hydration and performance, while Taurine supports muscle contractions, cellular health, and resilience against oxidative stress.
- 1500 MG SODIUM NITRATE AS NO3-T, 1000 MG AGMATINE SULFATE, 508 MG VASODRIVE-AP - The Arginine–eNOS–nitric oxide (NO) pathway is the primary driver of vasodilation, covered in this formula by L-Citrulline and Agmatine. The nitrate–nitrite–NO pathway, often neglected in pre-workouts, is leveraged here with a high dose of Nitrates to drive NO production even further. VasoDrive-AP promotes vasodilation from another angle by inhibiting ACE, which increases oxygen and nutrient delivery capacity.
- MIXES EFFORTLESSLY AND TASTES INCREDIBLE – With over 40 grams of active ingredients per serving, Gorilla Mode Nitric powder still nails taste and mixability. We use HydroPrime Glycerol and premium flavor systems tested for years to ensure every sip is smooth, clean, and delicious. No grit, chalkiness, or synthetic aftertaste—just massive pumps, peak performance, and a naturally colored pre-workout you’ll actually look forward to drinking.

- Caffeine-Free Pre-Workout – This evidence-based formula relies on proven performance enhancing and nitric oxide-boosting ingredients to deliver an incredible workout experience with zero filler. Expect intense pumps, improved endurance, and faster recovery without stimulants. The ultimate stim free pre workout.
- Premium Nitric Oxide Boosting – Featuring 6 grams of pure L-citrulline (not citrulline malate, which contains less active citrulline), 2 grams of arginine nitrate (NO3-T), and HydroMax glycerol to enhance blood flow, nutrient delivery, and muscle performance.

Part of getting a great pump and performance experience in your workout comes from being properly hydrated, something our competitors neglect. We are the pioneers of the non stim preworkout, with High Volume existing since 2012.
- Versatile and Stackable – Use High Volume solo for pumps and endurance or stack it with stimulant pre-workouts, BCAAs, or creatine for amplified performance, blood flow, and recovery support. An essential non stim pre workout to have in your gym bag. If you aren't looking to avoid caffeine, stack with an energy drink, or save it for a late night workout.
- Unmatched Flavor and Mixability – With refreshing taste and award-winning flavors like Guava Pineapple Punch and Sour Peach Candy, High Volume delivers a delicious flavor you will look forward to every day. And since it's a stimulant free pre workout, you can drink it anytime!
The Smart Buyer’s Guide to Non-Stimulant Pre-Workouts
Are you looking to boost your gym performance without the jitters and crash that come with caffeine? Non-stimulant pre-workouts are your answer! These supplements focus on improving blood flow, muscle endurance, and focus using ingredients that don’t rely on high doses of stimulants. This guide will help you pick the best one for your fitness goals.
Key Features to Look For
A great non-stim pre-workout focuses on three main areas: pumps, endurance, and focus. Look for these features when comparing products:
- Vascularity and “The Pump”: This is the main goal of many non-stim users. Look for ingredients that increase nitric oxide (NO) production. NO helps widen your blood vessels, letting more blood and oxygen reach your working muscles.
- Endurance and Stamina: These ingredients help delay muscle fatigue so you can push through those last few tough reps. They help manage the acid buildup in your muscles.
- Mental Clarity (Focus): Even without stimulants, you need to stay locked into your workout. Good non-stim formulas often include non-caffeine nootropics to sharpen your mind.
Important Ingredients: What to Find on the Label
The quality of a non-stim pre-workout truly depends on the ingredients it uses. Always check the serving size and the amount of each active ingredient. Here are the heavy hitters:
For Blood Flow and Pumps:
- L-Citrulline or Citrulline Malate: This is the king of pump ingredients. It converts to L-Arginine in the body, boosting nitric oxide. Aim for 6 to 8 grams per serving.
- Nitrates (e.g., Beetroot Extract): These also increase NO production, leading to better blood flow and oxygen delivery.
For Endurance and Power:
- Beta-Alanine: This ingredient helps buffer lactic acid in your muscles. You will feel a harmless tingling sensation (paresthesia) when you take it. Look for 3 to 5 grams.
- Creatine (Often included, but sometimes sold separately): While not strictly a pump ingredient, creatine boosts strength and power output significantly.
For Focus Without Jitters:
- L-Tyrosine: This amino acid supports the production of neurotransmitters that help maintain focus, especially when you are physically tired.
- Huperzine A or Alpha-GPC: These compounds help support cognitive function and mind-muscle connection.
Factors That Improve or Reduce Quality
Not all formulas are created equal. Pay close attention to how the ingredients are dosed.
Quality Boosters:
- Clinical Dosing: The best products use the amounts of ingredients proven effective in scientific studies (e.g., 6g of Citrulline).
- Transparent Labeling: You should clearly see the exact amount of every active ingredient. Avoid “proprietary blends” that hide ingredient amounts.
Quality Reducers:
- Underdosing: If a product lists a great ingredient but only gives you a tiny amount, it won’t work well.
- Excessive Fillers: Too many unnecessary additives or artificial sweeteners can sometimes detract from the core formula.
User Experience and Use Cases
Non-stim pre-workouts offer great flexibility. You use them when you need performance enhancement but must avoid stimulants.
When Should You Use It?
- Late-Day Workouts: If you train after 4 PM, a stim-free option prevents sleep disruption.
- Stacking: Many experienced users take a non-stim pre-workout for pumps and then add a small dose of caffeine separately, or use it alongside other non-stimulant supplements like creatine.
- Beginners: If you are sensitive to caffeine, this is the perfect starting point for pre-workout supplementation.
When you take it, you should feel a noticeable increase in muscle fullness and be able to complete more reps before your muscles burn out. The focus should feel smooth, not sharp or jittery.
10 Frequently Asked Questions (FAQ) About Non-Stim Pre-Workouts
Q: What is the main difference between stim and non-stim pre-workouts?
A: The main difference is caffeine. Non-stim pre-workouts do not contain high amounts of caffeine or other central nervous system stimulants. They focus on blood flow and endurance instead.
Q: Will a non-stim pre-workout still give me energy?
A: Yes, but differently. They provide the energy needed for muscle work (endurance) rather than the “wired” feeling you get from caffeine. You feel less fatigued.
Q: When is the best time to take a non-stim pre-workout?
A: Take it about 20 to 30 minutes before you start exercising. This gives the ingredients time to get into your bloodstream and start working on blood flow.
Q: Can I take this every day?
A: Generally, yes, because they lack stimulants. However, it is always best to cycle off any supplement occasionally to ensure your body keeps responding well to the ingredients.
Q: Why do some non-stim products make my skin tingle?
A: That tingling feeling, called paresthesia, comes from Beta-Alanine. It is harmless, but it means the ingredient is present and working to buffer acid in your muscles.
Q: Are non-stim pre-workouts good for evening workouts?
A: Absolutely. They are ideal for evening sessions because they improve performance without interfering with your ability to fall asleep later that night.
Q: Do I need to cycle off non-stim pre-workouts?
A: Cycling is less critical than with high-stim products, but it is still wise. Your body might get used to ingredients like Citrulline over time.
Q: How much L-Citrulline should I look for?
A: For best pump results, look for a total dose between 6 grams and 8 grams of L-Citrulline or Citrulline Malate per serving.
Q: Can I mix a non-stim pre-workout with creatine?
A: Yes, you can mix them. Many people mix their non-stim pre-workout powder directly with their daily creatine dose for convenience.
Q: What should I do if I don’t feel any pumps?
A: First, ensure you are taking the full recommended serving size. Second, make sure you are properly hydrated, as water is essential for achieving a good muscle pump.
