Did JYM Supplement Science Pre JYM Pre-Workout - Stim-Free 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 new panel image carries a Shopify upload stamp of 2026-10-27, which places the new label on the brand's page within 2026-08-03 to 2026-10-27; this is not a manufacture date and does not establish what is in a given tub. On 2026-11-07 the product page no longer references the earlier panel asset. Both panels were read twice independently with every field agreeing. 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.
