How to Choose a Pre-Workout for What You're Actually Training For

How to choose a pre-workout: match the formula to the session, not the marketing. Decide across three training goals — strength, endurance, and combat sport — then read the panel for dose per full scoop, like Gladiatore's printed 400mg of caffeine, and walk away from anything hiding a single dose inside a proprietary blend.

Updated August 2026. This is a buyer's guide, not a pitch. Black Stallion Supplements is a family-owned brand in Freehold, New Jersey, built by Robert Hart on one rule: print every dose and let people check the work. We read supplement labels for a living, so what follows is the method we actually use, and we use our own fully printed Gladiatore™ panel as the worked example only because every gram on it is visible to check against. Nothing below is medical advice. It is how to line a formula up against the training you are actually doing.

How do you choose a pre-workout for what you actually train?

You choose a pre-workout by starting with the session in front of you, not the tub on the shelf: name the goal, name the physical demand that goal puts on your body, then ask whether the panel actually meets that demand at a dose the research supports. The order matters. Most people buy the loudest label, feel the caffeine, and never check whether the ingredients that support their actual training are present at a dose that does anything.

A pre-workout is a stack of separate tools that do different jobs: stimulants you feel in the first ten minutes, pump ingredients that raise blood flow for one session, and slow builders like beta-alanine that only pay off after weeks. So the useful question is never "is this a good pre-workout" in the abstract. It is "does it carry the tools my session needs, at doses I can see." That is the whole method.

Do strength, endurance, and combat sports need different pre-workouts?

Yes. The three goals put different demands on the body, and a single scoop cannot be optimal for all of them at once, so the honest move is to know which one you are buying for. Strength work is short, heavy, and neurological. Endurance work is long and metabolic. Combat sport is a long, mixed effort that borrows from both. Each one leans on a different part of a pre-workout panel.

Here is the goal-to-look-for table. Read each line as three things collapsed together: the training goal, the demand it creates, and what to look for on a panel to meet it — with the printed Gladiatore dose as the checkable reference.

• Strength and power. The demand is short, maximal, repeated efforts with acid buildup between sets. Look for a real buffering dose — beta-alanine in the studied 4 to 6g range and betaine around 2.5g or more. Gladiatore prints 4g beta-alanine, 4g betaine anhydrous, and 800mg sodium bicarbonate, a second buffer.
• Endurance. The demand is sustained output and blood flow over a long duration. Look for a full nitric-oxide precursor dose and a stimulant that does not spike and crash. Gladiatore prints 7g L-citrulline malate (2:1) and 7g L-arginine for the pump pathway, plus 400mg theobromine, a longer-acting stimulant than caffeine alone.
• Combat sport and mixed sessions. The demand is focus and drive that hold across a long, varied effort. Look for the buffering and pump doses above plus a focus pairing so the stimulant does not read as jittery. Gladiatore prints 800mg L-theanine, 1g L-tyrosine, 400mg caffeine and 400mg theobromine.

The table is not saying one product wins. It says what a panel must carry to serve a goal, so you can hold any tub up to it — a formula that is all stimulant and 1g of citrulline is fine for a jolt and useless for the pump an endurance session needs.

How do you read a supplement label: dose per serving versus dose per scoop?

You read a supplement label by finding "servings per container" and "serving size" first, because a dose only means something once you know the scoop it is attached to — and many brands quote their best number against a serving you would never actually take. It is the most common way a label misleads without lying.

A brand lists impressive per-scoop doses, then quietly defines the scoop as a "maximum" serving while the directions tell you to start at half, so the dose you read and the dose you take drift apart. The fix is to do the arithmetic yourself: total grams in the tub, divided by the scoop you will really use, equals your true servings. On the Gladiatore panel the full scoop is 31.73g and every dose above — 400mg caffeine, 7g citrulline malate, 4g beta-alanine and the rest — is stated per that full scoop, with the half scoop listed as exactly half. Compare two tubs at the same real scoop first.

The second thing to read is whether a clinically studied dose is actually present. A checklist of the doses that show up in the research lives in what should be in a pre-workout, and the active-by-active breakdown for our own formula is on the Gladiatore ingredients page. The point of both is the same: a named ingredient at a token dose is marketing, and only the number tells you which one you are holding.

What does a proprietary blend let a brand hide?

A proprietary blend lets a brand print one combined weight for several ingredients so you cannot see the dose of any single one — which means you cannot tell whether the ingredient you are buying for is at a working dose or a sprinkle. It is the most important thing to check when you choose a pre-workout, and it is a binary test: either every active has its own printed number, or it does not.

Say a label reads "Power Blend, 6g" and lists citrulline, beta-alanine, betaine, and tyrosine underneath. That 6g could be 5g of cheap filler and a few hundred milligrams split across the three ingredients you actually wanted. Labeling rules require the total blend weight and descending order by weight, but not the individual doses, so the blend is legal and uninformative at once. We refuse to run blends at all, and the reasoning is in why we refuse proprietary blends. When one of two tubs uses a blend, you are not comparing two formulas — you are comparing one formula against a question mark.

How much stimulant should a pre-workout have for when you train?

The right stimulant load depends on your tolerance and on the time of day you train, not on how strong the tub claims to be — and a high dose like 400mg of caffeine is a training-day tool for experienced users, not a default. The FDA has noted that up to 400mg of caffeine a day is not generally associated with negative effects in healthy adults, and one full Gladiatore scoop is that entire daily figure in a single serving, which is exactly why it is built for people who already tolerate strong stimulants.

Match the load to the clock. Caffeine has a long half-life, so a 400mg evening scoop can sit on your sleep for hours, and lost sleep costs you more training than any pre-workout returns. If you train late, or you are new to stimulants, the printed half scoop at 200mg of caffeine is the honest starting point, and for some people a lower-stim option is the better buy. Gladiatore pairs its 400mg of caffeine with 400mg of theobromine, a longer, smoother stimulant, and 800mg of L-theanine to take the edge off the jitter — but pairing does not cancel the dose. It is still 400mg at a full scoop, plus 2.5mg of yohimbine, which raises sympathetic tone. The full dosing and timing rules are on the how to use page. If you are stimulant-sensitive, have any heart condition, or take medication, this is not a formula to reach for without talking to a physician first.

Buying your first pre-workout: what to change and what to leave alone?

For your first tub, change the dose you start with and leave the panel alone — the ingredients are fixed, but how you introduce them is under your control, and rushing it is how beginners scare themselves off a product that would have worked. Run it as a short protocol:

• Step 1 — start with a half scoop. On the Gladiatore panel that is 200mg of caffeine and half of every other dose. Take it 20 to 30 minutes before an easy session and see how your body reads a strong formula before you ever touch a full scoop.
• Step 2 — one serving per 24 hours, and no stacking. A full scoop is already a full day's caffeine on its own, so a coffee on top turns a training tool into an accidental overdose of the exact thing you are trying to stay sensitive to.
• Step 3 — judge the stimulant on day one, but judge the buffering over weeks. You will feel the caffeine, theobromine, and pump the first time. Beta-alanine is different: it works by raising muscle carnosine through consistent intake across roughly two to four weeks (Trexler and colleagues, 2015, Journal of the International Society of Sports Nutrition), so do not judge it on a single scoop.
• Step 4 — check yourself against the "not for" list before you buy, not after. A high-stim pre-workout is not for stimulant-sensitive people, first-time supplement users, anyone under 18, anyone pregnant or nursing, anyone with a heart condition, or anyone on medication. If you are in one of those groups, the question is not which pre-workout — it is whether to use one at all, and that is a physician conversation.

What you should never do to a first tub is dry-scoop it, double it because it "isn't hitting yet," or read a quiet first day as a dud when the accumulation ingredients simply have not accumulated. Leave the panel alone and change your protocol.

How to choose a pre-workout: quick FAQ

How do I choose a pre-workout as a beginner?

Start with your goal and your tolerance, not the strongest tub. Pick a formula whose panel prints every dose, check that the ingredients your training actually needs are present at studied doses, and begin with a half serving to assess how you respond. For a strong formula like Gladiatore that half scoop is 200mg of caffeine. If you are new to stimulants or train late in the day, a lower-stim option may be the better first buy.

What is the best pre-workout for strength versus endurance?

They lean on different ingredients, so the best pre-workout for strength versus endurance is not the same tub. Strength and power work rewards buffering ingredients like beta-alanine (studied around 4 to 6g) and betaine, because the demand is short, repeated maximal efforts. Endurance rewards a full nitric-oxide precursor dose and a smoother stimulant for sustained output. Gladiatore prints 4g beta-alanine and 4g betaine for the buffering side and 7g each of L-citrulline malate and L-arginine for blood flow, so you can see which demand a panel is built to meet.

What does "dose per scoop" mean on a supplement label?

It means the amount of each ingredient you get in one scoop of the size the directions tell you to use — and it matters because some brands quote doses against a "maximum" scoop while directing you to take half. Always find "serving size" and "servings per container" first, then compare tubs at the same real scoop. On the Gladiatore label the full scoop is 31.73g and every dose is stated against it, with the half scoop listed as exactly half.

What is a proprietary blend and should I avoid one?

A proprietary blend prints one combined weight for several ingredients instead of a dose for each, so you cannot tell whether the active you want is at a working dose or a trace. When you are choosing a pre-workout, a blend is the clearest reason to put a tub back: you are comparing a known formula against a question mark. We refuse to use blends at all and print every gram, which is the standard behind the whole Black Stallion label.

How much caffeine should a pre-workout have?

That depends on your tolerance and when you train, not on the label's bravado. The FDA notes up to 400mg of caffeine a day is not generally associated with negative effects in healthy adults, and a full Gladiatore scoop is that whole daily figure at once, which is why it is built for experienced users and offers a 200mg half scoop. If you are stimulant-sensitive, train in the evening, or are new to caffeine, less is the right buy, and one serving per 24 hours with no other caffeine stacked on top is the rule either way.

Does a stronger pre-workout mean a better one?

No. "Stronger" usually means more stimulant, and more stimulant does nothing for the pump, buffering, or focus your session may actually need. A better pre-workout is one whose printed panel carries the ingredients your training goal demands at doses the research supports — which is a completely separate question from how big the caffeine number is.

Bottom line

How to choose a pre-workout comes down to three checks you can run on any tub in under a minute: confirm the panel carries the tools your training goal demands, read the doses against the scoop you will actually use, and reject anything hiding an ingredient inside a proprietary blend. Do that and the front of the tub stops mattering, because you are buying the panel, not the marketing.

If you want to run those checks on our formula, the active-by-active breakdown at printed full-scoop doses is on the Gladiatore ingredients page, the dosing and timing rules are on the how to use page, and more label questions are answered on the FAQ page. Gladiatore is one product built for experienced lifters, fighters, and combat athletes — a separate daily creatine option lives on the Creatine+ page.

Gladiatore is a high-stimulant formula built for experienced lifters, fighters, and combat athletes. Mix one scoop in 8 to 12 oz of cold water 20 to 30 minutes before training. Start with a half scoop to assess tolerance. Do not exceed one serving in 24 hours. Do not stack with other caffeine. It is not for stimulant-sensitive people, first-time pre-workout users, anyone under 18, anyone pregnant or nursing, anyone with a heart condition, or anyone on medication. Talk to a physician before use if you are unsure.
