5 limits on what this shows
  • The evidence establishes an observation window, not an exact reformulation date.
  • An observation date is the date FormulaSignal read a source. It is not a manufacture date and not the date a change was made.
  • 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 or human review is claimed. This Signal was confirmed by an agent under the standing delegation of 2026-08-03 and does not count toward the human-reviewed Signal target in the Company Proof Plan.
  • At least one endpoint did not record its claim set in full, so a claim present on one side and absent on the other is non-disclosure rather than removal.
  • At least one endpoint did not record its certification set in full, so a certification present on one side and absent on the other is non-disclosure rather than removal.
  • Record V1 releases a Signal on the date FormulaSignal records evidence review. No separate publication timestamp is recorded.
The full finding, in words

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.

  • Amino Acid Blend held at 5 g across both states.
  • Energy And Focus Blend held at 130 mg across both states.
  • Servings per container held at 30 across both states.
