Did ProSupps Mr. Hyde Max Pump change its formula?
THE SHORT ANSWER · CHANGED
Yes. A confirmed label change is on file. On ProSupps' own Hyde Max Pump Unflavored Supplement Facts panel, arginine nitrate (as NO3-T) 1 g was replaced by L-arginine alpha-ketoglutarate 2:1 1 g, and hawthorne berry fruit extract 100 mg is gone. The scoop went from 12.45 g to 12.67 g. Vitamin C 60 mg, L-citrulline 4 g, beta-alanine 3.2 g, betaine anhydrous 3 g and 20 servings did not move. Between labels seen Aug 30, 2025 and Aug 3, 2026.

What the confirmed change shows
On ProSupps' own Hyde Max Pump Unflavored Supplement Facts panel, arginine nitrate (as NO3-T) 1 g was replaced by L-arginine alpha-ketoglutarate 2:1 1 g, and hawthorne berry fruit extract 100 mg is gone. The scoop went from 12.45 g to 12.67 g. Vitamin C 60 mg, L-citrulline 4 g, beta-alanine 3.2 g, betaine anhydrous 3 g and 20 servings did not move.
The 2025 endpoint is the brand's own Unflavored panel image (Hyde-Max-Pump-SFP-Unflavored) served by the Wayback Machine on 2025-08-30 and shown in the product gallery of the archived Hyde Max Pump page of 2025-04-20; the 2026 endpoint is the Unflavored panel preserved from the current product page on 2026-08-03. 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.
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.

- 2 of 3 flavors on the brand's store (2026-10-20) have no panel read 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: Unflavored. US market only.

Method
How this page was made.
What FormulaSignal did
- Read the label ProSupps published for Unflavored, dated Aug 3, 2026, twice and independently: 17 of 17 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
ProSupps Mr. Hyde Max Pump: formula questions
Did ProSupps Mr. Hyde Max Pump change its formula?
Yes. A confirmed label change is on file. On ProSupps' own Hyde Max Pump Unflavored Supplement Facts panel, arginine nitrate (as NO3-T) 1 g was replaced by L-arginine alpha-ketoglutarate 2:1 1 g, and hawthorne berry fruit extract 100 mg is gone. The scoop went from 12.45 g to 12.67 g. Vitamin C 60 mg, L-citrulline 4 g, beta-alanine 3.2 g, betaine anhydrous 3 g and 20 servings did not move. Between labels seen Aug 30, 2025 and Aug 3, 2026.
My ProSupps Mr. Hyde Max Pump 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 Vitamin C (as Ascorbic Acid) 60 mg, L-Citrulline 4 g and Beta Alanine 3.2 g 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.
What did FormulaSignal check, and what not yet?
Checked: the Unflavored label from ProSupps, dated Aug 3, 2026, read twice with 17 of 17 fields matching. Not yet: 2 of 3 flavors on the brand's store (2026-10-20) have no panel read 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.
Will I find out if ProSupps Mr. Hyde Max Pump changes its formula later?
