Why Black Stallion Refuses Proprietary Blends

Flip over most pre-workout tubs and you hit a wall. Somewhere on the panel sits a line that reads "Energy Matrix" or "Pump Complex" or "Performance Blend," followed by a single number. 6,500mg. 12,000mg. One total for the whole stack. Underneath it, a list of ingredients with no individual numbers next to any of them.

That is a proprietary blend. It is the single biggest tell that a brand does not want you to know what you are actually buying.

Black Stallion does not use them. Not in Gladiatore™, not ever. Every gram is printed on the label, ingredient by ingredient, so you can verify exactly what is in the scoop before you ever dump it in the shaker. Here is why that matters, and why the blend is one of the oldest tricks in the supplement business.

What a proprietary blend actually is

A proprietary blend is a group of ingredients listed together under one name, with only the combined weight disclosed. The FDA allows it. Under the rules, a brand has to print the blend's name, the total weight of everything inside it, and the ingredients in descending order by weight. That is the whole requirement.

Read that again. Descending order by weight, total weight only. The brand never has to tell you how much of each thing is in there.

So a "Pump & Power Matrix 6,000mg" might be 5,800mg of cheap filler up top and a sprinkle of the three ingredients you actually came for at the bottom. The label is technically honest. The total is real. But the number that matters, the dose of each active, is gone.

The trick: hiding under-dosing behind one big total

This is where the blend stops being a "trade secret" and starts being a margin play.

Quality ingredients cost money. Citrulline at a real dose is not cheap. Betaine at a real dose is not cheap. Beta-alanine, tyrosine, theanine, dose them all properly and the cost per tub climbs fast. The blend gives a brand a way out. Print one impressive-looking total, list the expensive ingredients so they appear on the label, then dose them at a fraction of what the research used. The industry term for it is "fairy dusting." A pinch of an ingredient, just enough to legally name it, nowhere near enough to do anything.

You cannot catch it, because the per-ingredient number is hidden inside the blend. The total looks big. The individual doses are invisible. That is the entire point of the format.

It is not a fringe problem either. One analysis of 100 commercial multi-ingredient pre-workout labels found that roughly 44% of all listed ingredients were buried inside proprietary blends with no disclosed amount. Nearly half. That is the norm in this category, not the exception.

Why the dose is the whole thing

An ingredient on a label means nothing on its own. The dose is the product.

Take citrulline, the ingredient most associated with pump and blood flow. The studies that report performance and endurance benefits used real amounts. Research on citrulline malate has run trials around 6 to 8 grams taken before training, with one randomized crossover study dosing 8 grams an hour before muscle-endurance work. That is the range where the literature associates it with a training benefit.

Now picture a blend that lists citrulline but actually contains 500mg of it. Same word on the label. A fraction of the studied amount. It is unlikely to do much, and you would never know, because the number lives inside a total you cannot break apart.

The gap between 7 grams and a sprinkle is the gap between a formula dosed the way the research was run and one that just looks the part. The blend exists to hide which one you are holding.

What full-label transparency looks like

So here is the Gladiatore™ panel. Every active, every number, per one full scoop (31.73g). Nothing rounded into a "matrix." Nothing hidden.

• L-Citrulline Malate 2:1 — 7g. The real, studied range for pump and endurance support, not a label-dressing pinch.
• L-Arginine — 7g. A second nitric-oxide pathway ingredient, fully dosed alongside the citrulline.
• Betaine Anhydrous (TMG) — 4g. Research on betaine for power output commonly uses around 2.5g per serving; this sits above that.
• Beta-Alanine — 4g. The tingle ingredient. Studies on muscular endurance associate it with multi-gram daily intake.
• L-Tyrosine — 1g and L-Theanine — 800mg, for focus and to smooth the stimulant edge.
• Caffeine Anhydrous — 400mg and Theobromine — 400mg, the energy engine.
• Yohimbine — 2.5mg, itself a stimulant.
• Plus Vitamin C 1g, Sodium (bicarbonate) 800mg, and Magnesium (citrate) 45mg.

You can do the math yourself. You can compare it against any study you want to pull up. You can take it to a coach or a training partner who knows their numbers, and they can verify it in thirty seconds. That is the difference. A transparent label invites the audit. A proprietary blend forbids it.

This is not about a regulatory stamp. Supplements are not approved by the FDA, and no honest brand claims otherwise. The value of full-label transparency is simpler than that. It is the brand handing you the means to check its work. We print the doses because we want you to verify them.

Why this formula is dosed for who it is dosed for

Transparency cuts both ways. Print every number and you also have to be honest about who the formula is built for. 400mg of caffeine plus 400mg of theobromine plus yohimbine is a high-stimulant load. That is a deliberate build for experienced lifters, fighters, and combat athletes who already train hard on stimulants and know their tolerance.

It is not for everyone, and we will say so plainly. Gladiatore™ is not for stimulant-sensitive people, not for first-time pre-workout users, not for anyone under 18, and not for anyone pregnant or nursing. If you are unsure, talk to a physician before using it.

Even if you are experienced, respect the numbers. Start with a half scoop to assess how you respond. Half a scoop is half of every dose above, including 200mg of caffeine. Mix one scoop in 8 to 12 ounces of cold water about 20 to 30 minutes before training. Do not stack it with coffee, energy drinks, or any other caffeine source on top. Do not exceed one serving in 24 hours. And never dry-scoop it.

That guidance only exists because the doses are on the label. A brand hiding its caffeine inside an "Energy Blend" cannot tell you to start with half a scoop in any meaningful way, because you do not know what a scoop contains. Transparency is what makes responsible use possible.

The standard, stated plainly

A proprietary blend asks for your trust and gives you nothing to check it against. It is a closed door with a big number painted on it. The format survives because it lets brands look fully dosed while spending like they are not.

Black Stallion took the other road. Robert Hart built this family-owned brand in Freehold, New Jersey, on the idea that a serious athlete deserves to see exactly what they are putting in their body, at the exact amount. Gladiatore™ ships nationwide with every gram on the panel: 22 full-scoop servings per 698g tub, one Fruit Punch flavor, $54 with free shipping. No blends. No hidden totals. No sprinkles dressed up as doses.

If a label will not show you the numbers, it has a reason. Ours shows you all of them.
