Pre-Workout Excellence for 20+ Years
For over two decades, Gaspari Nutrition has led the way in supplement innovation. Our pre-workout powders are made in cGMP-certified facilities, guaranteeing top-notch quality and safety. With smooth mixing, delicious flavors, and options for various stimulant preferences, each scoop fuels the performance you expect.
Best pre-workout for beginners?
Start with a balanced formula and use half a scoop to test tolerance. Avoid extreme high stimulant products initially. Gaspari's SuperPump Max is a proven option with smooth energy. If you're sensitive to caffeine, try Proven Pump. It's completely stimulant free but still boosts performance.

Can women take pre-workout?
Yes, pre-workout works the same regardless of gender. Many women prefer half to three quarters of a serving based on body size and caffeine tolerance. Gaspari's formulas are fully transparent, so you know exactly what you're taking with no mystery blends or hidden ingredients.
Does pre-workout help you lose weight?
Indirectly. Caffeine boosts metabolism and lets you train harder, burning more calories. But pre-workout isn't a fat burner; it's a performance supplement. For targeted fat loss, pair it with proper diet and thermogenics like Gaspari's DTN8 or Cytolean.
Best pre-workout without caffeine?
Stimulant free pre-workouts use pump and endurance ingredients without caffeine; great for night training or caffeine sensitivity. Look for glycerol, L-citrulline, and nitric oxide boosters. Gaspari's Proven Pump is a liquid formula that delivers skin-splitting pumps with zero stimulants.
Can I stack pre-workout with other supplements?
Yes, but don't double up on stimulants. Smart stacks combine a caffeinated pre-workout with a stimulant free pump product. Gaspari's SuperPump Aggression pairs well with PLASMAJET capsules for maximum nitric oxide and vascularity without extra caffeine.
What’s in Pre-Workout?
Pre-workout supplements are packed with ingredients designed to enhance performance, energy, and focus during your workout. Here’s what you’ll typically find in our pre-workout formulas:
- Caffeine – Boosts energy, mental alertness, reaction time, and endurance to keep you performing at your best.
- Creatine – Supplies muscles with quick energy for short-duration activities like weightlifting, sprints, or high-intensity interval training (HIIT).
- Nitric Oxide (N.O.) Boosters – Includes powerful agents like L-arginine and L-citrulline to promote blood flow, fueling muscle pumps and enhancing performance.
- Beta-Alanine – Supports higher carnosine levels in muscles, helping to delay fatigue and keep you pushing harder for longer.
What Is the Best Pre-Workout?
Choosing the right pre-workout depends on your fitness goals, preferences, and tolerance to specific ingredients. Here are some key factors to help you decide:
- Stimulant vs. Stim-Free Pre-Workout
Stimulant pre-workouts deliver a noticeable energy boost with ingredients like caffeine and beta-alanine, which can cause a tingling sensation (paresthesia). If you prefer to avoid stimulants due to sensitivity, bedtime workouts, or personal preference, consider a non-stimulant or caffeine-free option. - Delivery Format
The most popular choice is pre-workout powder, which is quick and easy to mix with water. Other formats include ready-to-drink shots, capsules, and pre-mixed beverages, catering to a variety of preferences. - Intensity Levels
If you’re new to pre-workouts, start with an entry-level option that has fewer ingredients and lower doses. For experienced users, advanced or “extreme” pre-workouts feature higher doses and more potent ingredients for a stronger impact. - Flavor Options
Fruity flavors are the classic go-to, but there’s no shortage of exciting flavor options, including nostalgic collaborations with candy, drink, and snack brands. These keep your pre-workout experience enjoyable and fresh every time.
When Should I Take Pre-Workout?
Take pre-workout 20–30 minutes before you start training. This timing lets caffeine and nitric oxide boosters peak when you begin lifting. Avoid stimulant formulas within 4–6 hours of bedtime to protect sleep quality. Stimulant free options like Gaspari's Proven Pump can be taken anytime.
How Long Does It Take for Pre-Workout to Kick In?
Pre-workout kicks in within 20–30 minutes. You'll feel caffeine first as increased alertness, then beta-alanine tingles, followed by enhanced blood flow and pump. Full effects peak around 45–60 minutes after drinking it. Taking it on an empty stomach speeds absorption slightly.
How Long Does Pre-Workout Last?
Pre-workout effects last 1–3 hours, with the strongest impact in the first 60–90 minutes. Caffeine has a 4–5 hour half-life, so some energy may linger longer. Pump and endurance benefits typically carry through your entire workout. Avoid late-day dosing if sleep is a concern.
