Benefits

Gnarly Caffeine-Free Pre-Workout is the performance primer for athletes who want to show up ready without the stimulant, whether it’s an evening session, a second workout of the day, or a sensitive stomach. Science-backed ingredients at effective doses, no proprietary blends, no junk, no caffeine.

Multi-ingredient performance formula: citrulline malate, beta-alanine, vegan BCAAs and ginseng at clinically relevant doses

Zero caffeine: the same Gnarly Pre formula with the stimulant removed

Function

A great pre-workout isn’t just about energy, it’s about priming every system that determines performance. Gnarly Caffeine-Free Pre-Workout keeps the multi-ingredient approach of Gnarly Pre because different ingredients target different physiological levers, and removes the caffeine for athletes who train late, train twice, or simply don’t want a stimulant.

L-Citrulline / Citrulline Malate drives nitric oxide production, which dilates blood vessels and improves blood flow to working muscles. The result is better oxygen delivery, improved nutrient uptake, enhanced muscle pumps, and a meaningful impact on power output and endurance during high-intensity work.

Beta-Alanine buffers lactic acid accumulation in muscle tissue, extending the time before fatigue forces performance decline during high-intensity efforts. It’s the ingredient responsible for the harmless tingling sensation (paresthesia) some athletes experience, a sign it’s working. Beta-alanine benefits are cumulative, so consistent use is key.

Panax Ginseng supports natural energy and focus without a stimulant, and Vegan BCAAs stimulate muscle protein synthesis to help you recover for the next session.

How to Use

Mix 1.5 tbsp (14g) with 10–12 oz of cold water. Consume 20–30 minutes before training.

Caffeine-free, so it works for evening sessions and anyone sensitive to stimulants. Want a moderate dose? Mix ½ scoop with ½ scoop of regular Gnarly Pre for about 90mg of caffeine per serving.

Stack: Follow with Gnarly Hydrate during your session and Gnarly Whey or Vegan Protein post-workout for a complete pre-to-post training system.

Ingredients

Active Ingredients (Strawberry Lemonade Caffeine Free): Citrulline Malate 2:1 (5g), Vegan BCAAs 2:1:1 — L-Leucine, L-Isoleucine, L-Valine (4g), CarnoSyn® Beta-Alanine (2.5g), Panax Ginseng Root Extract (150mg)

Other Ingredients (Strawberry Lemonade Caffeine Free): Stevia Leaf Extract, Natural Flavors, Citric Acid, Malic Acid, Beet Juice Powder (for color), Calcium Silicate, Silicon Dioxide

Gnarly Effect

Citrulline’s pump and blood flow benefits are active within 30–45 minutes. Without caffeine there is no stimulant kick or crash, so it can be taken late in the day.

Results vary based on training intensity, diet, sleep, and individual physiology, but may include improved training intensity and volume, faster warm-up times, extended time to fatigue during high-output efforts, and improved strength and power output over time with consistent use.

Frequently Asked Questions

No fine print, no confusion. These are the questions we hear most about our products, our standards, and how Gnarly fits into real training days.

Gnarly PRE contains BCAAs, do I still need to take Gnarly BCAAs?

We recommend taking Gnarly PRE 20-30 minutes before your workout, drinking Gnarly BCAAs during your workout and then following up with your favorite Gnarly protein. This keeps leucine levels (one of the branched chain amino acids critical to preventing muscle breakdown and promoting muscle growth) in your blood high and maximizes the benefit you get from your training while minimizing soreness and fatigue.

When I take Gnarly PRE my face and hands tingle, is this normal?

Tingling in your hands and face after taking Gnarly PRE is completely normal. Gnarly PRE includes Beta Alanine, an ingredient that increases muscular carnosine levels and helps buffer muscular acidity. Beta Alanine also causes “pins and needles” type tingling, the medical term for which is paresthesia. Paresthesia is a harmless side effect but can be reduced or avoided by taking a smaller dose of Gnarly PRE.

I'm sensitive to caffeine, can I still take Gnarly PRE?

If 180mg of caffeine is a bit too much for you, remember that Gnarly Preworkout comes in a caffeine free strawberry lemonade flavor. We also have a lot of athletes that end up mixing ½ scoop of the caffeinated Gnarly Preworkout with ½ scoop of the caffeine free Preworkout - this provides a much more moderate 90mg of caffeine/serving while providing full doses of BCAAs, Beta Alanine and Citrulline Malate.

When should I take Gnarly PRE?

We recommend taking Gnarly PRE 20-30 minutes before your workout/training session.

I lost my scoop!

1 Serving of Gnarly Preworkout is 14-15g.  14-15g of powder is approximately 1 Tablespoon.

Where’s the scoop?!

No, we didn’t forget yours. We’ve come to the hard decisions to ditch our scoops for the sake of Mother Nature.

Losing the scoops will save an estimated 28,000lbs (that’s a Freight Ship with Rocky Balboa as the Captain) of plastic per year. It’s a no brainer for our beloved Earth.

Now don’t just start pouring powder into your drinks willy-nilly. Have a regular spoon laying around? Good. Here’s the kitchen equivalent:

2 scoops with 10-12 oz of liquid, or 1/3 cup (50 grams) with 10-12 oz of liquid.
