- Location
- Golden, Colorado, United States [1]
- Run by
- Horizon Analytical LLC (a Delaware limited liability company, per its Terms) [1]
- Accreditation
- No accreditation claimed. The lab's Compliance and Testing Policy says it will not use wording such as 'ISO accredited' or 'certified' unless the exact claim, legal entity, site, method, scope, dates and supporting evidence have been verified. Not found in the A2LA, IAS or PJLA directories on 2026-10-16. No accredited scope. The policy says sterility testing is currently performed by SD PharmLabs. [2] [3] [4] [5]
- How to check a COA
- Lookup by report number, with an optional lot number, on the Verify COA page. [6]
- Who can send samples
- Commercial, consumer and research customers, according to the lab's Compliance and Testing Policy. [2]
- Turnaround
- The services page says typical turnaround is 48 to 96 hours, and its price table offers 5-7 day and 1 day options (25 and 19 days for the full QC panel). [7]
Also worth knowing
- We couldn't retrieve a peptide COA carrying its name, so its match to the “Horizon Analytical” named on vendors' COAs is probable, not confirmed. The prices shown are the default view of its price table (oral thin films). [7]
Tests it offers
- Purity by HPLC [8]
- Identity by LC-MS (molecular weight and fragmentation patterns) [9]
- Quantity (mg) by LC-MS/MS quantitative methods [7]
- Endotoxin (LAL) [9]
- Sterility, performed by a subcontractor (SD PharmLabs) [2]
- Heavy metals (elemental impurity screening) [7]
