Cellucor C4 Sport, 213g (30 Serves)

Cellucor C4 Sport, 213g (30 Serves) is a pre-workout from Cellucor built for lifters, and NSF Certified for Sport athletes, who want measurable training energy without a mystery ingredient list. Each 8.5g scoop, roughly one level scoop, provides 135mg of caffeine anhydrous plus the C4 Sport Performance Blend delivering 4900mg of CarnoSyn beta-alanine, creatine monohydrate and arginine AKG per serve. At $49.45 NZD for 30 serves, it suits training blocks where you need repeatable output more than a stimulant wall.

How Cellucor Pre-Workout works

The 135mg of caffeine anhydrous in Cellucor C4 Sport, 213g (30 Serves) works on your central nervous system by blocking adenosine receptors, the same receptors that build up over a session and make effort feel harder than it is. Blocking them keeps you feeling more alert and lowers your rate of perceived exertion, which is why a moderate, well-timed caffeine dose can carry a session further than a huge one taken too early.

The C4 Sport Performance Blend works differently. Beta-alanine is the precursor to carnosine, a compound your muscles use to buffer the hydrogen ions that build up during hard, repeated efforts, the same acidity that makes your legs or lungs give out mid-set. Creatine monohydrate sits in the same blend and works through the phosphocreatine system, helping regenerate ATP fast enough to support short, high-output efforts like sprints or heavy sets. N-Acetyl-L-Tyrosine, in the Energy Blend alongside caffeine, is a precursor to dopamine and noradrenaline, the neurotransmitters tied to focus and drive under physical stress.

Why choose Cellucor C4 Sport, 213g (30 Serves)

Cellucor discloses only blend totals and caffeine individually, which is standard for a proprietary-blend pre-workout, but the totals themselves are generous: 4900mg across the Performance Blend and 1135mg across the Energy Blend beyond caffeine. If you are weighing up whether this is worth $49.45 NZD, three things stand out beyond the headline caffeine and beta-alanine content.

• Just 5 calories per scoop, so it fits into a cut or a bulk without meaningfully touching daily macros.
• A built-in B-vitamin trio: 45mcg vitamin B12 (1875% DV), 15mg niacin (94% DV) and 0.5mg vitamin B6 (29% DV), covering micronutrients your body uses in normal energy metabolism.
• 110mg of sodium as sodium citrate, a modest electrolyte addition on top of whatever fluid you are already drinking through a longer or hotter session.

None of that replaces a proper diet or hydration plan, but it means Cellucor C4 Sport, 213g (30 Serves) is doing more per scoop than caffeine and beta-alanine alone.

Getting the most from it

Most people take one scoop of Cellucor C4 Sport, 213g (30 Serves) mixed with 200 to 300ml of water, around 20 to 30 minutes before training, so the caffeine has time to take effect and any beta-alanine tingle has settled before the first set. If you already take a dedicated creatine product daily, there is no need to add extra on training days, since the Performance Blend already tops up that total. On longer or hotter sessions, pairing it with something from our electrolytes range covers more ground than the 110mg of sodium in the tub alone, and a serve from our protein range afterward supports recovery once the training energy has done its job. If you are comparing it against the rest of our pre-workout range to find the right fit for your week, the moderate 135mg caffeine dose here tends to suit people training multiple times a week rather than chasing one heavy stim hit.
