What the confirmed change shows
RSP Nutrition AminoLean Pink Lemonade label images observed on 2023-10-25 and 2026-10-17 declare 1.5 g and 1 g of Weight Management Blend per two-scoop serving. The labeled serving mass changes from 8.2 g to 7.80 g; both panels show 30 servings.
The blend name is the manufacturer's wording and does not establish an outcome. Member ingredient amounts remain undisclosed, so this finding does not identify which member amounts changed. Newly listed vitamin declarations do not prove prior absence. The 130 mg Energy and Focus Blend and separate 125 mg total caffeine footnote describe different quantities. Dates are source observations, not manufacture, rollout, or transition dates; this record does not establish customer-container contents. No laboratory testing is claimed.
Tastes different?
Check your tub against this label. Line by line.
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.

Not checked yet
- Retail labels have not been compared with the brand's own store.
- Earlier labels may exist that the Record has not recovered; a missing observation is not proof nothing changed.
Labels read from the brand's own store (DTC) channel only. Other channels may sell a different label. The panel is declared product-wide; flavor-specific panels read: Pink Lemonade. US market only.
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 Pink Lemonade, dated Oct 17, 2026, twice and independently: 75 of 75 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: 1 confirmed change 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 Energy / Pre Workout: formula questions
Did RSP Nutrition AminoLean Energy / Pre Workout change its formula?
Yes. Weight Management Blend went from 1.5 g to 1 g. Between labels seen Oct 25, 2023 and Oct 17, 2026, compared like for like.
My RSP Nutrition AminoLean Energy / 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 17, 2026 on this page (it declares Vitamin C (as Ascorbic Acid) 45 mg, Vitamin B6 (as Pyridoxine Hydrochloride) 1.7 mg and Vitamin B12 (as Cyanocobalamin) 2.4 mcg 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.
How do I know if I have the old or new RSP Nutrition AminoLean Energy / Pre Workout?
Read the Supplement Facts panel. The label seen Oct 25, 2023 declares 1.5 g weight management blend; the label seen Oct 17, 2026 declares 1 g. The date on a tub is not a formula date, so go by the amounts printed.
What did FormulaSignal check, and what not yet?
Checked: the Pink Lemonade label from RSP Nutrition, dated Oct 17, 2026, read twice with 75 of 75 fields matching. Not yet: Retail labels have not been compared with the brand's own store; Earlier labels may exist that the Record has not recovered; a missing observation is not proof nothing changed.
