Always consult a qualified healthcare professional before starting any new supplement, especially if you are pregnant, breastfeeding, or managing a health condition. Individual results vary.
Training hard while trying to lean out is a balancing act. You want energy for big lifts, sharp focus to push through fatigue, and metabolic support to keep your body burning efficiently — all without hammering your nervous system with a single-ingredient stimulant blast. Emrald Labs Pre Shred is engineered to do all three at once. It's not just a pre-workout. It's a dual-purpose formula designed for people who train with purpose and want every session to count toward a leaner, stronger result. Explore the full pre-workout range at Berwick Supplements to find the right fit for your training style.
- Pre Shred is a fully disclosed, 8 g-per-scoop formula — no proprietary blends hiding doses below effective levels.
- 225 mg caffeine anhydrous paired with 125 mg L-Theanine may help support smooth, sustained energy without the crash typical of single-stimulant pre-workouts.
- 1,500 mg Acetyl-L-Carnitine and 125 mg green tea extract are included to support fat metabolism as part of a balanced diet and training program.
- Nootropic ingredients — Alpha-GPC, L-Tyrosine, Theobroma cacao — may help support focus and mood during demanding training sessions.
- For all-day metabolic support, Faction Labs Deficit and Emrald Labs Carnitine+ pair well as non-stimulant daytime additions.
- Available in 10 flavours including the best-selling Blue Crush — mix with 250–300 ml of cold water 20–30 minutes pre-session.
What Is Emrald Labs Pre Shred?
Emrald Labs is an Australian sports nutrition brand known for formulating products with transparent labels and research-referenced ingredients. Pre Shred is their flagship pre-workout, built specifically for athletes in a calorie deficit or active cut phase — though it performs just as well for anyone who wants a clean, focused training session.
Each 8 g scoop contains 14 calories, 2.8 g carbohydrates (1.8 g sugars), 7 mg sodium, 40 mg potassium, and less than 1 g protein. The low-calorie profile keeps it compatible with most diet approaches, including intermittent fasting protocols where training in a fasted state is common.
What separates Pre Shred from a standard pre-workout is the layered approach to performance: stimulant energy, nootropic focus, and metabolic-support compounds all working in the same scoop. You can read more about choosing a pre-workout in our Pre-Workout Guide for Australia.

The Dual-Purpose Advantage: Energy + Metabolic Support in One Scoop
Most people buying a pre-workout during a cut end up taking two separate products — a stimulant pre-workout and a fat-burner — which stacks stimulants, adds cost, and makes it harder to manage total daily caffeine. Pre Shred is designed to collapse that into one well-dosed product.
During Your Session
The caffeine-theanine stack and L-Tyrosine go to work quickly, supporting alertness and mental sharpness so you can maintain intensity even while under-fuelled. Alpha-GPC adds a cognitive dimension that's particularly noticeable during technical lifts or skill-based training. For a deeper look at how stimulant timing affects your results, see our guide on when to take fat burners for optimal results.
Supporting Your Metabolism
The Acetyl-L-Carnitine, green tea extract, green coffee bean, and CoffeeBerry® compounds are included to support fat metabolism and energy production as part of a calorie-controlled diet and training program. Research suggests these compounds may assist the body in utilising stored fat for fuel more efficiently — though diet and training remain the primary drivers of body composition change.
Recovery Between Sessions
Pterostilbene and juniper berry are not typical pre-workout inclusions — they're in the formula to support antioxidant defence, which matters when you're training frequently in a caloric deficit. Less oxidative stress between sessions may support recovery quality.
Complementary All-Day Support: What to Stack with Pre Shred
Pre Shred covers your training window. For support across the rest of the day — particularly appetite and metabolic rate — two non-stimulant (or low-stimulant) products pair well without adding to your total caffeine load.
Faction Labs Deficit Fat Burner
A thermogenic formula designed to support appetite control and metabolic function throughout the day as part of a structured nutrition and training program.
Shop Now →Faction Labs Deficit is a dedicated fat-burner designed for all-day use. Taken separately from Pre Shred (and away from your training window), it provides metabolic and appetite support across hours when Pre Shred is not active. Read our overview of fat burners in Australia to understand which products suit different goals and training approaches.
Emrald Labs Carnitine+
Stimulant-free carnitine formula designed to support fat utilisation and energy metabolism throughout the day. Can be taken alongside meals or fasted cardio sessions.
Shop Now →Emrald Labs Carnitine+ is a stimulant-free option that works well on rest days or as a morning addition on training days. Since it contains no caffeine, it doesn't compound with Pre Shred and can be used alongside fasted cardio or between meals to support carnitine levels across the full day — particularly relevant given that dietary carnitine intake from food can be inconsistent, especially on a higher-protein cut.
How to Use Pre Shred
- Assess Tolerance First: If you're new to stimulant pre-workouts or have a moderate caffeine sensitivity, start with half a scoop (4 g) mixed with 150–200 ml of cold water. Gauge your response before moving to a full dose.
- Full Performance Dose: Once comfortable, use one full scoop (8 g) mixed with 250–300 ml of cold water.
- Timing: Take 20–30 minutes before training. For fasted morning sessions, Pre Shred can also be taken first thing to support a metabolic kickstart — though food around training generally supports performance better for most people.
- Daily Limit: Do not exceed one scoop per day. Avoid use within 6 hours of bedtime due to the stimulant content.
- Cycling: Consider taking 1–2 days off per week to maintain sensitivity to the stimulant components. This is particularly worthwhile during extended cut phases.
Flavours & What to Expect
Pre Shred comes in 10 flavours, all developed to dissolve cleanly and taste well-balanced rather than overpoweringly sweet. Current options include:
- Blue Crush — smooth blue raspberry, the best-seller
- Watermelon Snow Cone — light and refreshing, suits hot-weather sessions
- Bubblegum Grape — bold and nostalgic
- Pineapple Splice — tropical and bright
- Plus six additional flavours available in-store and online
Most users report feeling the energy effect within 15–20 minutes. The L-Theanine's moderating influence on caffeine tends to produce a focused, settled feeling rather than the hard peak-and-crash pattern of a high-caffeine-only formula. Consistent use over 7–14 days is typically when metabolic-support benefits become more noticeable alongside a structured training and nutrition plan.
- Pre Shred is a genuinely dual-purpose product — the same scoop supports both training performance and metabolic function, making it particularly well-suited to a cut or body-recomposition phase.
- The fully disclosed label with no proprietary blends means you know exactly what you're getting and at what doses — a rarity at this price point.
- The caffeine-theanine ratio is well-balanced; most users can expect clean, focused energy rather than jitter-heavy stimulation.
- For all-day coverage, adding Faction Labs Deficit or Emrald Labs Carnitine+ as a non-stimulant daytime complement rounds out a sensible, manageable stack.
- Start with half a scoop if you're new to stimulant pre-workouts; one full scoop for experienced users.
- Available at Berwick Supplements in-store (Berwick VIC) and online with fast local delivery across the Casey and Cardinia region.
Frequently Asked Questions
Can I stack Pre Shred with BCAAs or a protein shake?
Yes — Pre Shred mixes well alongside BCAAs, electrolytes, and protein shakes. The key consideration is total daily caffeine intake. If you're also consuming coffee, energy drinks, or other caffeinated products, factor Pre Shred's 225 mg into that total and stay within a level that suits your individual tolerance. The general guidance for healthy adults is to remain under 400 mg of caffeine per day from all sources.
Will Pre Shred cause jitters or a crash?
Most users report smooth, focused energy rather than jittery overstimulation, largely because of the 125 mg L-Theanine in the formula. L-Theanine may help take the hard edge off caffeine's stimulant effect while preserving the alertness and focus benefits. If you're particularly sensitive to caffeine, beginning with half a scoop is recommended. The crash risk is also reduced by the CoffeeBerry® and green coffee extract, which provide a more sustained polyphenol-based energy component alongside the caffeine peak.
How long does it take to notice results?
Energy and focus effects are typically felt within 15–30 minutes of consumption and persist for 2–4 hours depending on individual metabolism. Appetite-support and metabolic-function benefits associated with the Acetyl-L-Carnitine, green tea, and bitter orange compounds are generally more noticeable after 1–2 weeks of consistent use alongside a structured diet and training program. Supplements support results — they don't create them independently of your overall approach.
Is Pre Shred suitable for women?
Yes. Pre Shred is designed for all athletes regardless of gender. Many female users start at half a scoop (4 g) to assess their response to the stimulant content, then adjust accordingly. The metabolic-support, focus, and appetite-management compounds are equally relevant for women in an active cut or body-recomposition phase. As with any supplement, consult a healthcare professional if you are pregnant, breastfeeding, or managing any health condition.
Can I take Pre Shred on rest days or for fasted cardio?
Pre Shred can be used on days when you're doing fasted cardio or light active recovery, though the stimulant content means some users prefer a lower dose (half scoop) in those contexts. On full rest days, most users are better served by a stimulant-free option like Emrald Labs Carnitine+ to maintain metabolic support without unnecessary nervous system load.
How does Pre Shred compare to a standalone fat burner?
Pre Shred covers your training window with energy, focus, and metabolic-support ingredients combined. A standalone fat burner like Faction Labs Deficit is designed for all-day use and typically contains a different compound profile optimised for thermogenesis and appetite support outside of training. The two products complement each other — Pre Shred for the session, Deficit for the rest of the day — rather than being duplicates. See our fat burner guide for a full comparison of how these product types work differently.
