One of the wider curated catalogs — branded GLP agonists across many dosages, recovery blends, and a full run of Khavinson bioregulators — where covered products ship their own gallery of third-party COA images from Vanguard Laboratory (ISO 17025 HPLC-UV/VIS purity + quantity) and Janoshik Analytical, alongside USP <85> endotoxin and <71> sterility panel scans. Purity runs consistently high and safety-panel coverage is unusually complete.
Readers who want per-product third-party COAs with genuine safety-panel depth (endotoxin, sterility) across an unusually broad catalog, and the widest range of GLP dosages in one place.
The GLP products are branded — GLP-2 (T) is tirzepatide, GLP-3 (R) is retatrutide, GLP-1 (S) is semaglutide, GLP-4 (C+S) is a cagrilintide/semaglutide blend — and the ISOFLOW / Nova KLOW / Diamond Glow blends are mapped to their components for $/mg comparison. The storefront opens with an age gate; prices shown reflect any active sale.
Per-product third-party COA gallery (Vanguard / Janoshik) with USP safety panels
In-scope products publish galleries of third-party COA images: Janoshik Analytical and Vanguard Laboratory HPLC-UV/VIS purity and quantity reports plus USP <85> endotoxin, <71> sterility, and <61> microbial panel scans. Janoshik reports that print a unique key can be checked at janoshik.com/verify, while the Vanguard COAs are named accredited-lab documents without a public verification portal.

Representative product pages showing how this catalog exposes report or verification paths. Examples, not proof for every current lot.
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.
