Every gaming supplement brand claims the same thing. Clean energy. Zero crash. Peak focus. Clinically backed ingredients.

So how do you actually tell them apart?

You read the label. Then you check the doses. Then you look up what the research says those doses need to be. That's it. No brand loyalty, no marketing copy. Just the data.

Here's the 2026 breakdown across three of the most talked-about gaming supplements: Buffs, G Fuel, and Gamer Supps.

The Transparency Problem

Before we get into ingredients, there's a structural issue worth calling out directly.

Both G Fuel and Gamer Supps use proprietary blends, meaning they list the ingredients inside a complex but don't tell you how much of each one you're actually getting. The label shows you a total weight for the blend and a list of what's inside it, but the individual doses are hidden.

This matters more than most people realise. A supplement can include L-Tyrosine, L-Theanine, and Citicoline, all legitimate research-backed cognitive ingredients, and still be completely underdosed if the blend total is too small to deliver effective amounts of each one. Listing an ingredient and dosing it effectively are two different things entirely.

Buffs publishes every single ingredient with its individual dose. 14 ingredients, 14 numbers, fully visible on the label. That's the baseline we're comparing from.

Caffeine: The Foundation

All three products lead with caffeine. Here's how they compare:

Buffs: Caffeine Anhydrous 150mg + TeaCrine 100mg
G Fuel: Caffeine 140–150mg (disclosed)
Gamer Supps: Organic Caffeine 100mg (disclosed)

Buffs is the only formula running a dual-stage caffeine system. Caffeine Anhydrous hits fast for an immediate energy response. TeaCrine is a naturally occurring compound structurally similar to caffeine that extends the duration of that energy without building tolerance the way straight caffeine does. You don't need to keep increasing your dose over time to get the same effect.

G Fuel's caffeine dose is solid and comparable. Gamer Supps runs lighter at 100mg, roughly one cup of coffee, which is intentional for their market positioning but falls short for a serious six-hour session.

L-Theanine: The Jitter Killer

L-Theanine is what separates a clean caffeine experience from a jittery, anxious one. Research consistently shows effective pairing with caffeine at doses between 100mg and 200mg.

• Buffs: L-Theanine 150mg (disclosed)
• G Fuel: Listed in some formulas, dose undisclosed, inside proprietary blend
• Gamer Supps: L-Theanine present, dose undisclosed, inside 159mg total nootropic blend

Buffs hits the clinical sweet spot at 150mg. G Fuel includes L-Theanine in some but not all formulas, and because it's inside a proprietary blend, you can't verify the dose. Gamer Supps' entire nootropic and antioxidant complex totals just 159mg across all ingredients combined. For L-Theanine alone to be dosed at an effective 100mg, it would have to represent more than 60% of that entire blend, leaving almost nothing for every other ingredient on the list.

Tyrosine: The Stress and Focus Ingredient

L-Tyrosine replenishes dopamine and noradrenaline, the neurotransmitters your brain burns through during high-stakes ranked matches and sustained cognitive effort. Research puts effective doses between 500mg and 2,000mg.

• Buffs: Tyrosine 350mg (disclosed)
• G Fuel: L-Tyrosine listed as the largest component of a 1,001mg focus complex, individual dose undisclosed
• Gamer Supps: L-Tyrosine present inside 159mg total blend, individual dose undisclosed

G Fuel's focus complex totals 1,001mg, with L-Tyrosine listed first, suggesting it's the dominant ingredient in that blend. That's a reasonable indication the dose is meaningful, though without disclosure you can't confirm it. Gamer Supps' 159mg total blend makes it mathematically impossible for L-Tyrosine to be dosed anywhere near an effective level. Buffs sits at 350mg, below the upper research range but clearly disclosed and in a formula where TeaCrine and Citicoline are picking up additional cognitive load.

Citicoline: The One Most Supplements Skip

Citicoline is a direct precursor to acetylcholine, the neurotransmitter responsible for memory, attention, and executive function. Clinical doses in research sit around 250mg to 500mg. It's expensive to include at effective doses, which is why most gaming supplements leave it out entirely.

• Buffs: Citicoline 150mg (disclosed)
• G Fuel: Not present
• Gamer Supps: Not present

This is the clearest point of formula differentiation. Buffs includes it. Neither competitor does.

Blood Flow: The Ingredient Category Both Competitors Ignore

Nitric oxide boosters, specifically Nitrosigine and S7, enhance blood flow and oxygen delivery to the brain, directly supporting visual processing speed and reaction time. These are not standard gaming supplement ingredients. They're expensive, they're bulky, and most brands don't bother.

• Buffs: Nitrosigine 600mg + S7 50mg (both disclosed)
• G Fuel: Not present
• Gamer Supps: Not present

Absorption: The Ingredient That Makes the Rest of It Work

AstraGin is a clinically studied compound that increases the gut's ability to absorb amino acids and nutrients. Without it, a percentage of every other ingredient passes through without being absorbed.

• Buffs: AstraGin 15mg (disclosed)
• G Fuel: Not present
• Gamer Supps: Not present

The Side-by-Side Summary

The Bottom Line

G Fuel built the category and still runs a solid caffeine-forward formula. Gamer Supps wins on price-per-serving and has built one of the strongest communities in gaming supplements, but the 159mg total nootropic blend is a real limitation when you're trying to move the needle on cognitive performance.

Buffs is the only formula in this comparison with full ingredient transparency, a dual-stage energy system, Citicoline, dedicated blood flow support, and an absorption compound. It's also the only one made in Australia, which means it ships in days not weeks, and you're not paying currency conversion on every tub.

You don't have to take our word for it. The label is right there. Check the numbers.
