CBUM Thavage - South Beach Slush, 532g (40 Serves)

CBUM Thavage is Raw Nutrition's flagship pre-workout, built under Chris Bumstead's CBUM line for lifters who want a fully loaded stimulant formula rather than a stripped-back everyday pre. Each 40-serve tub of CBUM Thavage - 6 Peat delivers 130mg of caffeine and 3g of L-citrulline per scoop, plus a full pump and focus stack, scaling to a heavier two-scoop dose once tolerance is established. It suits lifters who want a real energy curve alongside genuine blood-flow and cognitive support, not a stimulant hit with little else behind it.

How CBUM Pre-Workout works

Caffeine is the backbone of any stimulant pre-workout, and CBUM Thavage carries 130mg of it per scoop as caffeine anhydrous, topped up with 32mg of di-caffeine malate and 25mg of theobromine for a broader release than caffeine anhydrous gives on its own. The alertness effect comes down to adenosine receptor blockade: caffeine competes with adenosine in the central nervous system, which is part of why energy and focus tend to arrive together instead of as one jittery spike. L-theanine, included at 75mg, is commonly paired with caffeine because it tends to smooth the stimulant curve without dulling it.

The pump side leans on 3g of L-citrulline, 750mg of Nitrosigine (an inositol-stabilized arginine silicate) and 500mg of agmatine sulfate, three separate routes into the same nitric oxide pathway rather than one. Citrulline converts to arginine in the kidneys and feeds nitric oxide synthesis, the process that widens blood vessels and drives the vascular pump lifters chase mid-set. Beta-alanine, at 1.6g per scoop, works differently again: taken consistently it raises muscle carnosine levels, which buffers the acid build-up behind the burning, fatigue-driven failure typical of high-rep training. Betaine anhydrous, dosed at 1.25g, is included for its role in cellular hydration and power output under load.

Why choose CBUM Thavage

CBUM Thavage does not stop at caffeine and citrulline. The label also carries an electrolyte layer and a B-vitamin inclusion, both there to round out the formula rather than just bulking out the panel. A few things worth knowing before you commit a scoop:

• Each batch is tested under the Informed Sport programme, worth knowing if you compete in a tested sport or simply want assurance the formula has been screened for banned substances.
• The electrolyte layer includes 100mg sodium and 149mg chloride from pink Himalayan salt, 45mg potassium from Nitrosigine and coconut water concentrate, and 1g of taurine, ingredients tied more to hydration and cellular fluid balance than to raw stimulant output.
• At 5 calories and 1g of carbohydrate per scoop, the formula sits low enough that it will not eat into a tracked macro target, and it carries 5mg of vitamin B6 and 50mcg of vitamin B12 alongside the stimulant and pump actives.

Getting the most from it

Start with a single scoop, taken 30 to 45 minutes ahead of training, until you know how 130mg of caffeine sits with you. The formula is built to scale, which is why two scoops exist as an option once tolerance is established rather than as the default entry point. Most lifters treat a pre-workout like this as the anchor of a training-day stack, pairing a scoop with a straightforward creatine base, since citrulline and beta-alanine work on separate pathways to creatine with no real overlap between them.

If a session runs long, or training happens through an NZ summer, plain water alone may not replace what a hard session sweats out, and that is where a dedicated electrolytes product can extend past the 100mg of sodium already sitting in a single scoop. Once training is done, the job of CBUM Thavage is finished for the day; recovery nutrition picks up from there, and it stacks cleanly alongside whatever protein or amino approach you already run.
