✓Purity consistency between unitsWithin house limit

3 units, each above 99.00% (the lab's reporting bound) · every unit printed the same bound, so the report shows no difference between units (the bound allows at most 1.00 pt) · house limit · caution past 0.50 pt, outside past 1.00 pt · per-unit USP <621> results

✓Content consistency between units · SelankWithin house limit

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)

✓ConformityUnits 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 · house check · agreement across all tests, unit to unit; QA approval corroborates

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.
