Gold Standard pre-workout: what the label actually says
750mg of citrulline against a 3000mg to 6000mg research range, and two ingredients with no credible human evidence at the dose used. The full ON Gold Standard panel, read at the stated serving.
Short answer: the caffeine and creatine are fine, the rest is thin. Optimum Nutrition's Gold Standard pre-workout scores 64. The headline problem is 750mg of citrulline against a researched range of 3000mg to 6000mg, which is under a quarter of the bottom of it.
Optimum Nutrition built its reputation on whey, and Gold Standard is one of the most recognised names on the shelf. Recognition and dosing are different things. Here is the panel at the 11g serving the label states.
| Ingredient | Per serving | Reads as |
|---|---|---|
| Creatine monohydrate | 3400mg | a real daily dose |
| Beta-alanine | 1500mg | under the studied range |
| Caffeine | 175mg | moderate, honest |
| Citrulline | 750mg | a quarter of the low end |
| Acetyl L-carnitine HCl | 375mg | little evidence at this dose |
| N-acetyl L-tyrosine | 250mg | below the studied range |
| PerforMelon | 250mg | little evidence at this dose |
The citrulline is the problem
750mg. Research on citrulline for exercise performance runs roughly 3000mg to 6000mg, so this is about a fifth of the bottom of the range.
For scale, two of its direct competitors carry 5000mg of pure citrulline and around 2700mg once the malate arithmetic is done. Effective citrulline across the three runs 5000, 2700 and 750. That is a sevenfold spread on the ingredient the whole category is built around, and none of it is visible on the front of any of the three tubs.
Citrulline is also the expensive ingredient in a pre-workout, which is usually the explanation when a well-known brand carries a fraction of what a smaller one does.
The creatine is the best thing on the panel
3400mg of monohydrate, comfortably inside the 3g to 5g maintenance range and the highest of the three products we have compared. If you are taking this alongside a separate creatine supplement, count both.
The caffeine is moderate and honest
175mg, slightly under the 200mg its competitors use and well under the 400mg daily figure EFSA and the FDA both cite. The serving is stated plainly at 11g with no two-scoop games.
For anyone sensitive to stimulants that is a point in its favour rather than against.
Three ingredients doing very little
This is where the score goes.
N-acetyl L-tyrosine at 250mg. Work on tyrosine for cognitive performance under stress generally uses 500mg to 2000mg. 250mg is below the bottom of that.
Acetyl L-carnitine at 375mg and PerforMelon at 250mg both came back with no credible human evidence at the amounts present.
None of those three are harmful. They lengthen the ingredient list, and a long ingredient list is the thing people read as sophistication when it is usually the opposite: room on the panel spent on names rather than on doses.
What to do
- Find the citrulline line first on any pre-workout. It is the ingredient with the widest spread between products and the biggest effect on whether the tub does anything.
- Count the ingredients that carry a real dose, not the ingredients. Seven names with three meaningful amounts is a three-ingredient product.
- Do not read brand recognition as formulation. The most recognised name here has the least citrulline of the three by a factor of four.

Verdict reads the label, not the reputation. Photograph the supplement facts panel and it pulls every dose, compares each against the amounts used in published research, and adds up your whole stack. It reports the arithmetic. It does not tell you what to take.
