Turn your tub to the Supplement Facts panel. If an amount differs, you hold a different label from the one read here. If every line matches, the label does not explain the difference.

Method
How this page was made.
What FormulaSignal did
- Read the label Optimum Nutrition published for Watermelon Candy, dated Oct 24, 2026, twice and independently: 63 of 63 fields agreed.
- Kept that label with the day each was seen and its source.
- Counted a change only between two dated labels of the same flavor, size and sales channel: 0 confirmed changes on file.
- Printed every gap the Record knows about, above, instead of leaving it out.
What it did not do
- No look inside your tub. A product record does not establish what a particular container holds, and label dates are not manufacture dates.
- No taste test and no lab test. Every figure is what a label or a brand's own page declares, not what was measured in a tub.
- No score and no winner. Differences are measured and shown; nothing is rated.
- No payment and no preview. No brand paid to appear, and none saw this page before it was published.
- No health advice. Whether an ingredient or an amount suits you is a question for a clinician.

Questions
Optimum Nutrition Gold Standard Pre-Workout: formula questions
Did Optimum Nutrition Gold Standard Pre-Workout change its formula?
No confirmed formula change is on file. The label Optimum Nutrition published, dated Oct 24, 2026, was read twice and 63 of 63 fields agreed. The search for earlier labels is partly done, so an earlier label may still exist.
My Optimum Nutrition Gold Standard Pre-Workout tastes or feels different. Is it a new formula or a bad batch?
A label can answer half of that: whether the formula on the label changed. Compare the Supplement Facts panel on your tub with the label dated Oct 24, 2026 on this page (it declares Vitamin D (as Cholecalciferol) 12.5 mcg, Thiamin (as Thiamin Hydrochloride) 2 mg and Niacin 20 mg per serving). If your amounts differ, you hold a different label from the one on file. If they match, the label does not explain the difference. FormulaSignal does not test what is inside a tub.
What did FormulaSignal check, and what not yet?
