Label read twice. Both readings agree. Not a laboratory test, safety certification, or endorsement of the product. How Signal Verified works
Method
How this page was made.
What FormulaSignal did
- Read the label RSP Nutrition published for Maui Pineapple, dated Aug 3, 2026, twice and independently: 41 of 41 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
RSP Nutrition AminoLean MAX Pre-Workout Naturally Sweetened: formula questions
Did RSP Nutrition AminoLean MAX Pre-Workout Naturally Sweetened change its formula?
No confirmed formula change is on file. The label RSP Nutrition published, dated Aug 3, 2026, was read twice and 41 of 41 fields agreed. The search for earlier labels is partly done, so an earlier label may still exist.
My RSP Nutrition AminoLean MAX Pre-Workout Naturally Sweetened 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 Aug 3, 2026 on this page (it declares Beta Alanine 1600 mg, Nitrosigine (Inositol-Stabilized Arginine Silicate) 1500 mg and BCAA 2:1:1 (Instantized) 1500 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.
