Before an exosome number goes on a label, five things belong on file.
- The method and instrument that produced it.
- Whether it was measured on the raw ingredient or the finished product.
- How many lots, with lot numbers and dates.
- A blank: the same formula without the vesicle ingredient, measured the same way.
- The unit, written out in full: per mL, per gram or per vial, at release or at expiry.
One lot shows what one sample measured on one day. We treat three lots as the floor behind a label claim. That is how we work, not a rule from a regulator.
If you already have these and want a second read, an Exosome Claim Audit covers every claim on one product, in writing, in 5 business days. About the Claim Audit
