Honest Peptide lists research-only vials with the strength on the size option, including house names GLP-1 S for semaglutide, GLP-2 TZ for tirzepatide, and GLP-3 R for retatrutide. Blend sizes such as GLOW 10/10/50 mg are the component amounts; the comparable vial total is their sum. The public COA library includes current and older certificates. Bacteriostatic water and acetic acid stay off the vial comparison.
Readers who want public vial prices, including blend totals such as GLOW 70 mg and KLOW 80 mg, and certificates that can be checked at Freedom Diagnostics, Janoshik, or Chromate.

Checked September 25, 2026Public COA library with Janoshik, Freedom Diagnostics, and Chromate verification
The public COA library publishes certificate images. Freedom Diagnostics search codes, Janoshik task-and-key reports, and Chromate job-and-access reports resolve at those laboratories under Honest Peptide. A matched certificate documents the tested sample. It does not cover every vial or an unlisted safety panel. 2 older HPLC images are Vanguard Laboratory certificates without a public lookup code.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
