CBUM Essential - Fruit Burst, 420g (30 Serves)

CBUM Essential - Blue Raspberry is a 420g pre-workout tub from CBUM, built for lifters who want a full dose of pump and focus ingredients without stacking on stimulants. Each tub holds 30 serves, and the label is fully disclosed, so you can see exactly what is going into each scoop. It sits at the moderate end of the pre-workout category, enough drive to get through a heavy session without the jitter of a high-stim formula. If you train most days and want something you can use consistently, this is built around that use case.

How CBUM Pre-Workout works

The 200mg of natural caffeine in CBUM Essential works on the central nervous system, blocking adenosine receptors that would otherwise signal fatigue, which is why a scoop before training tends to sharpen focus and lift perceived energy. Paired with it is 2000mg of L-tyrosine, an amino acid your body uses to build dopamine and noradrenaline, the two catecholamines most involved in drive and concentration under physical stress. Together the two ingredients target the mental side of a session, staying switched on for the last few sets and not just the first ones.

On the physical side, the formula leans on 4000mg of L-citrulline, an amino acid that converts to arginine in the body and supports nitric oxide production, the process behind the vasodilation that gives you a fuller pump and better blood flow to working muscle. Beta-alanine, dosed at 3200mg, raises muscle carnosine levels over time, which helps buffer the acid build-up that causes muscular fatigue during higher-rep sets, and explains the tingling sensation some people feel on the skin. Taurine, included at 1000mg, plays a role in cell hydration and electrolyte balance, rounding out a formula built around performance during the session rather than pure stimulation.

Why choose CBUM Essential

CBUM Essential Blue Raspberry sits in the Raw Nutrition CBUM range as the everyday option rather than the high-stim version, which matters if you train most days of the week and do not want your tolerance climbing every few months. The formula also includes 200mg of Pink Himalayan Salt per serve, adding electrolytes to a stack that is otherwise built around pump and focus actives. A few things set it apart from a typical pre-workout tub:

• Informed Sport certified, so it has been tested for banned substances, relevant if you compete or are drug-tested at work.
• 200mg of Pink Himalayan Salt per serve adds electrolyte support alongside the citrulline and beta-alanine.
• 30 full serves per 420g tub, so one purchase covers close to a month of daily training at a single scoop per session.

Blue Raspberry is one of nine flavours in the CBUM Essential line, alongside options like watermelon, peach mango and orange, so if you finish a tub and want a change, the same formula is available in a different profile.

Getting the most from it

Take one scoop around 20 to 30 minutes before training, giving the caffeine and tyrosine time to kick in before your first working set. Because the caffeine dose is moderate, it also works as an everyday pre-workout rather than something you cycle on and off, though anyone sensitive to stimulants should start with a partial scoop to see how they respond.

It stacks cleanly with a daily creatine dose, since neither ingredient competes for absorption, and plenty of lifters run it alongside a whey or plant protein shake post-session to cover both the training window and recovery. If you are building a full stack rather than buying pieces individually, start with CBUM Essential Blue Raspberry for training days, add creatine for the daily base, and browse the rest of the pre-workout range if you want to compare it against other formulas before committing to a tub.
