08 — Questions
Good questions.
How much caffeine is in 4 Gauge Pre-Workout?
150 mg per 10 g scoop — about a strong cup of coffee. It is paired with 200 mg L-theanine, which is why the energy feels steady rather than wired.
Will it give me jitters or a crash?
It is built to avoid both: a moderate 150 mg of caffeine paired with 200 mg of L-theanine. Sensitivity varies from person to person, so if you are unsure, start with half a scoop.
Will it make my skin tingle or itch?
No. 4 Gauge contains no beta-alanine, the ingredient that causes the tingling and itching common with other pre-workouts.
What is it sweetened with?
Stevia and natural flavor. There is no sucralose, no sugar alcohols and no artificial colors.
Is 4 Gauge a good pre-workout for women?
Yes. Moderate caffeine, no beta-alanine and every dose on the label make it an easy fit for most women who train. Read more about 4 Gauge for women.
Can I take it with creatine?
Yes. 4 Gauge includes 1,000 mg of creatine monohydrate, a supporting amount rather than a full daily dose. If you want a complete daily serving, add PowerPhase Creatine.
Is it vegan or gluten free?
By ingredients, yes — 4 Gauge is vegan and gluten free. It is not currently certified for either.
Is it third-party tested?
Yes. Every batch is tested by an independent lab for potency, heavy metals and microbials.
Where is it made?
In our own GMP-certified facility in Ogden, Utah.
What is VIP Refill?
VIP Refill is our subscription: 4 bottles for $119.96 ($29.99 per bottle) with free shipping, delivered every 6 months. You can change the schedule to every 4 or 8 months, skip a delivery, or cancel anytime. Your first delivery includes a free shaker.
What's the difference between the 4-bottle order and VIP Refill?
The 4-bottle order is $135 one-time. VIP Refill is $119.96 per delivery on a recurring schedule you control. Same four bottles, same flavors — the only difference is the price and the recurring delivery.
Can I mix flavors in a 4-bottle order?
Yes. Any combination of Fruit Blast, Frozen Lemonade and Pina Colada that adds up to four bottles.
How much does it cost per workout?
$1.00 per workout on VIP Refill, $1.13 on a one-time 4-pack, and $1.50 for a single bottle.
