Did NutraBio Base Pre-Workout change its formula?

• 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 2025 endpoint is the brand's own panel image (21981-sfp, Blue Raspberry) served by the Wayback Machine on 2025-03-28 and referenced by the archived Base product page of 2024-12-05. The 2026 endpoint is the panel preserved from the current product page on 2026-08-03, also Blue Raspberry. Each was read twice independently with every field agreeing. The window is two observation dates, not a launch or manufacture date, and tubs with the earlier label may remain on shelves. No laboratory testing is claimed.
• An ingredient stated as removed or added is a difference between two label declarations that were each read in full. It is not evidence about what the product contains beyond what its label declares, and it is not a manufacturing date.
• 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.
• The original review date is retained for this record. It is not an independently recorded publication timestamp.
