Certificate of Analysis
Hair Growth Formula
Hair Growth Formula carries more distinct actives than anything else in the range, and each one needs its own method. High dose biotin is straightforward to assay. Keratin and hydrolyzed collagen are proteins, so they are identified by peptide profile rather than by weight alone. The botanical extracts are verified by species, because herbal powders are where substitution happens most often. A single certificate has to clear all of it before the lot is released.
All Lab TestingEvery Lot, Before Release
What We Test For
Biotin is quantified to confirm the 5,000 mcg declared per serving. Hydrolyzed collagen and keratin are identified by peptide profile to confirm the proteins named on the panel. MSM is verified for identity and purity as methylsulfonylmethane. The vitamin and mineral fraction is assayed as a full panel against the Supplement Facts declaration, and botanical ingredients are confirmed by species and plant part. Heavy metals are screened by ICP-MS for lead, arsenic, cadmium and mercury. Microbiological testing covers total plate count, yeast and mold, E. coli, Salmonella and Staphylococcus aureus.
How to Check a Lot
Reading Your Certificate
A certificate of analysis is a one page summary of what an independent laboratory found in one specific lot. The lot number at the top matches the number printed on the base of your bottle, so you can confirm you are reading the right document. Each row lists a test, the specification it has to meet, and the result that was actually measured. Results appear as a numeric value, as Pass, or as Not Detected, which means the substance was below the laboratory's limit of detection. Heavy metal results are reported in parts per million and compared against the limit set for that ingredient class. If a single row falls outside specification the lot is rejected and no certificate is ever issued. Certificates are added to this page as each new lot clears testing.
