Which Bulk Nutrients Pre Workout Should I Choose?

Compare Bulk Nutrients Pre Workouts

Here's how our pre workout range compares on price, serving size, caffeine content and key ingredients.

Ultra’s single-serve reference: 8.3g, 199mg caffeine, 30 single serves and approximately $1.47 per use.

Which Bulk Nutrients Pre Workouts Cost Under $50?

All three Bulk Nutrients pre workouts in this comparison cost under $50, but their serving quantities and cost per use differ.

Pre Workout Non-Stim offers the lowest cost per serve, while Pre Workout 101 is the more affordable caffeinated option when comparing Ultra at its full double serve.

Of course, price isn't everything. The ingredients, caffeine content and type of training support you want are just as important.

Which Bulk Nutrients Pre Workout Has the Most Caffeine?

Ultra Pre Workout contains the most caffeine at its recommended double serve, delivering 398mg per 16.6g. Pre Workout 101 contains 272mg per 13.2g serve, while Pre Workout Non-Stim contains no caffeine.

It's worth knowing that a single 8.3g serve of Ultra contains 199mg of caffeine, less than the amount in a full serve of Pre Workout 101.

More caffeine doesn't automatically mean a better workout, though. Your tolerance, training time and other sources of caffeine all matter.

For healthy adults, Food Standards Australia New Zealand identifies 400mg per day as a level generally not associated with adverse effects, with 200mg as a single-dose reference level. Individual sensitivity varies, and some people need to avoid caffeine altogether.

Always follow the product directions and consider your total caffeine intake, including coffee, energy drinks and other supplements.

What's the Difference Between Our Three Pre Workouts?

While caffeine is one of the biggest differences, each formula contains a combination of ingredients designed to support different aspects of exercise performance.

Here's what makes each one worth considering.

Pre Workout 101: Our All-Rounder for Regular Training

If you want a pre workout that combines energy, focus and performance support, Pre Workout 101 is a solid place to start.

With 272mg of caffeine per serve, it provides a substantial stimulant boost alongside ingredients that support strength, endurance and blood flow.

Its formula includes:

Pre Workout 101 is designed for regular gym-goers who want more than caffeine alone, with ingredients to complement a range of strength and resistance training sessions.

However, 272mg is still a significant amount of caffeine, so it's important to consider your tolerance before use.

Which Pre Workout 101 Flavour Is HASTA Certified?

Pre Workout 101 in Berry Lemonade is part of our HASTA-certified range.

HASTA certification involves independent batch testing for substances prohibited in sport, providing additional assurance for athletes who may be subject to anti-doping testing.

You can find available batch reports and certification details on the Pre Workout 101 product page.

Remember, certification applies to specific products and flavours, so always check the details for the product you're purchasing.

Ultra Pre Workout: Our High-Stim Option for Experienced Users

Looking for something with a bit more kick?

Ultra Pre Workout is our advanced high-stim formula, developed for experienced users who know their stimulant tolerance and want a more intensive pre workout.

At its recommended double serve, Ultra delivers 398mg of caffeine alongside additional stimulant ingredients and compounds selected to support focus and performance.

Its formula includes:

Ultra is designed for experienced pre workout users seeking a stronger stimulant formula, rather than those just starting out with caffeinated supplements.

With 398mg of caffeine in a double serve, it's particularly important to follow the label directions and account for any other caffeine consumed throughout the day.

Pre Workout Non-Stim: Performance Support Without Caffeine

Not every workout needs a caffeine hit.

Pre Workout Non-Stim contains zero caffeine, making it our option for people who prefer to avoid stimulants, manage their caffeine intake or train later in the day.

Rather than relying on caffeine for alertness, Non-Stim focuses on ingredients associated with blood flow, muscle pumps and exercise performance.

Its formula includes:

At $25 for 25 serves, it's also the most affordable option in our pre workout comparison on a per-serve basis.

Whether you're heading to the gym after work or simply prefer training without stimulants, Non-Stim provides an alternative to traditional caffeinated pre workouts.

And while it won't deliver the same immediate stimulant effect as caffeine, that doesn't mean it can't complement a demanding training session.

What's the Difference Between Caffeine-Free and Natural Pre Workout?

Caffeine-free and natural might sound similar, but they describe two different things.

Caffeine-free means a product contains no caffeine. Natural generally refers to the origin or type of ingredients used in a formula.

For example, a pre workout containing naturally sourced caffeine is still a caffeinated product. Likewise, a caffeine-free pre workout isn't necessarily made entirely from natural ingredients.

The term natural also doesn't tell you how strong a pre workout is or whether it contains other stimulants.

If you're trying to avoid caffeine, check the ingredient list and caffeine content rather than relying on descriptions such as natural.

For a caffeine-free option in our range, Pre Workout Non-Stim contains 0mg of caffeine per 10g serve.

Can You Use Different Pre Workouts for Different Training Sessions?

Absolutely! Your training needs aren't necessarily the same every day, so your pre workout doesn't have to be either.

For example, you might prefer Pre Workout 101 for regular daytime sessions and switch to Non-Stim when training in the evening.

Experienced stimulant users may choose Ultra for sessions where they want a stronger stimulant formula, provided it suits their tolerance and the product directions.

The key is choosing based on what your session calls for, rather than assuming more stimulants will always produce better results.

And remember, pre workouts aren't necessarily designed to be combined. Always check ingredient overlap, total caffeine intake and the directions on each product before considering multiple supplements.

Find the Right Pre Workout for Your Training

Still deciding? Here's the quick version.

Choose Pre Workout 101 if you want an all-round formula for regular gym sessions, with caffeine, creatine and other performance-supporting ingredients.

Choose Ultra High-Stim Pre Workout if you're an experienced stimulant user looking for our advanced high-stim formula.

Choose Pre Workout Non-Stim if you want caffeine-free support for muscle pumps, endurance and performance, particularly for evening training.

Ultimately, the best pre workout is the one that suits your goals, training schedule and caffeine tolerance.
