CBUM Essentials Charged - Blue Rathberry, 400g (25 Serves)

CBUM Essentials Charged is a fully disclosed pre-workout from CBUM built for lifters who want a strong, stimulant-driven session rather than a mild energy top-up. Each scoop carries 350mg of caffeine anhydrous alongside 6000mg of L-citrulline, giving you the drive to start heavy and the blood flow to sustain it through your working sets. This tub is the Blue Rathberry flavour, 480g and 30 servings, and it sits in the CBUM Essentials Charged range alongside Sour Watermelon for anyone who wants the same 350mg caffeine dose in a different taste.

How CBUM Pre-Workout works

The pump and endurance side of CBUM Essentials Charged rests on two amino acids working through different pathways. L-citrulline converts to L-arginine in the kidneys, raising nitric oxide production and widening blood vessels, so more oxygen and nutrients reach working muscle. Beta-alanine raises the muscle's carnosine stores instead, which buffer the hydrogen ions that build up as you push through higher reps, and that buffering is why some people feel a tingling sensation after dosing.

On the stimulant side, the 350mg caffeine anhydrous dose is paired with Dynamine (methylliberine) and theobromine, compounds that work alongside caffeine rather than replacing it. Alpha-GPC adds choline, a precursor the brain uses to build acetylcholine, the neurotransmitter tied to focus. L-tyrosine, dosed at 2000mg per serve, supports mental performance when caffeine and training stress are both elevated.

Why choose CBUM Essentials Charged

CBUM Essentials Charged uses a fully disclosed label, so every dose in the eight-ingredient panel is printed in milligrams instead of hidden inside a proprietary blend. You know exactly what a 16g scoop delivers before you take it, which matters with a stimulant dose this strong.

• Informed Sport certified, so athletes under a testing programme can use it with confidence.
• 200mg of pink Himalayan salt per serve helps replace sodium lost through sweat.
• Dynamine and theobromine round out the caffeine dose, giving a broader stimulant complex than caffeine alone.

Getting the most from it

Mix one scoop of CBUM Essentials Charged with 250 to 350ml of cold water and drink it 20 to 30 minutes before training, giving the caffeine and citrulline time to reach effective blood levels. Because this is a 350mg caffeine dose, avoid taking it within 6 hours of bedtime unless your tolerance is already high. Stack it with a creatine product for strength work, or add electrolytes on longer, hotter sessions.

Some lifters cycle CBUM Essentials Charged with a lower-stimulant option through the week, then return to the full dose for heavy training days. Browse the pre-workout range to compare stimulant levels before you commit.
