What the confirmed change shows
On ProSupps' own Mr. HYDE Xtreme Supplement Facts panel, Beta-Alanine rose from 2.5 g to 3,200 mg per scoop, N-Acetyl L-Tyrosine from 50 mg to 350 mg and GABA from 25 mg to 50 mg. Choline Bitartrate 500 mg and 30 servings did not move. The scoop grew from 7.8 g to 14.36 g, and the caffeine and yohimbe lines were rebuilt.
Both endpoints are first-party panel images from ProSupps' own storefront, preserved on their observation dates and each read twice independently with every field agreeing. On 2026-08-03 the product page also carried a second panel image the brand had named 'mr-hyde-xtreme-30-serve-sfp-old-formula', and it printed the same formula as the Green Apple panel; by the preserved page of 2026-09-26 only the new panel appears, so the change happened between 2026-08-03 and 2026-09-26 on the page, and the window states observation dates, not a launch or manufacture date. Older tubs may remain on shelves. The 2026-08-03 panel also prints Nitrosigine 500 mg, L-Citrulline Aspartate 500 mg, Creatine HCl 250 mg, L-Theanine 50 mg, TeaCrine 25 mg, Di-Caffeine Malate 70 mg, a 50 mg Caffeine Citric Acid Blend, yohimbe extract 3 mg (8% yohimbe) and a footnote of 378 mg actual caffeine; the 2026-10-24 panel prints L-Citrulline 3,000 mg, Creatine Monohydrate 2,500 mg, yohimbe extract 2 mg (2%), Yohimbine HCl 2 mg, Rauwolscine 0.5 mg and Dynamine 62.5 mg. The Caffeine Anhydrous line itself reads 300 mg on the first panel and 400 mg on the second, and niacin reads 25 mg NE and 30 mg; because the first panel spreads caffeine across three lines and the niacin lines are printed on different bases, neither is stated as a like-for-like change. Those lines are kept on each capture but no total caffeine or stimulant change is stated. 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.

Method
How this page was made.
What FormulaSignal did
- Read the label ProSupps published for Green Apple, dated Oct 24, 2026, twice and independently: 51 of 51 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 Xtreme: formula questions
Did ProSupps Mr. Hyde Xtreme change its formula?
Yes. Caffeine went from 300 mg to 400 mg. Beta-Alanine went from 2.5 g to 3.2 g, N-Acetyl L-Tyrosine went from 50 mg to 350 mg and Gamma-Aminobutyric Acid went from 25 mg to 50 mg. Between labels seen Aug 3, 2026 and Oct 24, 2026, compared like for like.
My ProSupps Mr. Hyde Xtreme 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 24, 2026 on this page (it declares Vitamin B3 (as Niacin) 30 mg, Power Performance Matrix 8.7 g and Beta-Alanine 3200 mg 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 ProSupps Mr. Hyde Xtreme?
Read the Supplement Facts panel. The label seen Aug 3, 2026 declares 300 mg caffeine; the label seen Oct 24, 2026 declares 400 mg. The label seen Aug 3, 2026 declares 2.5 g beta-alanine; the label seen Oct 24, 2026 declares 3.2 g. The label seen Aug 3, 2026 declares 50 mg n-acetyl l-tyrosine; the label seen Oct 24, 2026 declares 350 mg. The label seen Aug 3, 2026 declares 25 mg gamma-aminobutyric acid; the label seen Oct 24, 2026 declares 50 mg. 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 Green Apple label from ProSupps, dated Oct 24, 2026, read twice with 51 of 51 fields matching. Not yet: 4 of 5 flavors on the brand's store (2026-10-24) 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 Xtreme changes its formula later?
ProSupps Mr. Hyde Xtreme is re-checked within 180 days, and it is on the monitoring schedule so the next label change is looked for. Save it to your Locker free to keep its dated label beside the one you take. A change counts only when two dated labels of the same flavor, size and sales channel differ.
