Method
How this page was made.
What FormulaSignal did
- Read the label MuscleTech published for Fruit Punch, dated Oct 4, 2026, twice and independently: 78 of 78 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: 0 confirmed changes 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.

My MuscleTech Platinum 100% EAA+ 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 4, 2026 on this page (it declares Calcium (as calcium potassium phosphate citrate) 40 mg, Phosphorus (as dipotassium phosphate, calcium potassium phosphate citrate) 40 mg and Magnesium (as magnesium oxide, magnesium bisglycinate chelate) 35 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.
