Historical timeline
Comparable formula states.
Dates below are observation dates. They are not exact reformulation dates.
Historical formula evidence is not yet sufficient for a reliable comparison. This does not establish that the product never changed.
Confirmed Signals
Reviewed changes in the public Record.
No confirmed public Signal is associated with this product. This is not a claim that the product never changed.
Research-dose context
Selected evidence, not a universal effective dose.
These comparisons retain the studied protocol, source, and limitations. They do not establish safety, effectiveness, or a dose recommendation for this product.
Qualifying research context is unavailable for the current public formula.
Cautions and regulatory records
A filing and a documented risk are not the same thing.
These attach to declared ingredients, not to this product as a whole. Nothing here establishes that the product is safe or unsafe. Talk with a qualified health professional.
No documented caution is recorded against the declared ingredients on this Record. That is not a finding that the product is safe.
Where the sources disagree
What we could not read cleanly.
A disagreement between sources is recorded rather than smoothed into one confident number. None of these is a Signal.
No source conflict is recorded on this Record. That is not a claim that every source agrees, only that none we read disagreed.
Use your own numbers
Check the cost of your tub.
Use the price you paid and your label’s protein grams. If you have a matching lab report, the unit converter keeps its reporting limits intact; this Record does not establish heavy metal levels in your tub.
