3 units tested for purity, each printed >99.00% · net peptide content · selank 10.59 / 10.91 / 11 mg · net peptide content · semax 10.32 / 9.85 / 9.83 mg
Conformity: Units agree — every reported unit passed on all 11 test rows · purity: every unit above the same 99.00% bound, no difference reported · content spread (Selank) 3.8% within the house limit · content spread (Semax) 4.9% within the house limit · QA approval corroborates: Vanguard Laboratory, Tori Johnson, Operations Manager, 2026-07-17
11 results on the report · 4 rows computed from the per-unit values · 2 labs · each test used up to 5 vials from this lot (rows are not added together) · every row names the chapter or house rule it follows

3 units: 10.59 / 10.91 / 11 mg · spread 0.41 mg, 3.8% of the mean · house check · caution past 5%, outside past 10% · USP <905> is the compendial reference for between-unit uniformity (10 units; not claimable on 3)

A chapter number names the method or limit a result follows; it does not describe the product. Chapters below 1000 are procedures or limits; 1000-series chapters are informational. USP <905> is the compendial test for between-unit uniformity: it assays 10 units, so a 3-unit certificate cannot yield its acceptance value — the content row is a house check with <905> named as the reference only.
