CURATED VENDOR PROFILE
NextGen Peptides
A Los Angeles–branded research storefront (ngpeptide.com) with openly listed vial prices and a public COA library of ILS Laboratories PDFs that resolve at portal.ils-lab.com under the NextGen Peptides client name — distinct from the separately curated NextGenPeps brand.
Same formula for every vendor: verifiable testing evidence forms the backbone; third-party reviews adjust it within a bounded range. How scoring works →

NextGen Peptides sells research-only singles and blends with prices on the product pages, including branded TRZ/GLP-3 strengths and GLOW/KLOW blends. Its public COA library hosts batch PDFs; PeptideBenchmark confirmed the embedded ILS verify links live at the lab under client NextGen Peptides. Comparable capsules and ready sprays appear in their format-specific Pricing lanes; oral drops and multipacks remain outside current supported comparisons.
Readers who want a U.S. catalog with public ILS COAs that resolve at the lab under the NextGen Peptides client name, and who understand this is a different brand from NextGenPeps (nextgenpeps.com).
Not the same company as curated NextGenPeps (nextgenpeps.com) — different storefront, catalog, and COA surface. TRZ and GLP-3 are branded names for tirzepatide and retatrutide. Some product titles omit mg and rely on variation labels or COA-library doses. Comparable capsules and ready sprays appear in their own Pricing lanes and are not mixed into vial $/mg; oral drops and multi-vial kits remain outside current supported comparisons. Manufacturing / “USA-made” language remains vendor-stated.

Checked August 3, 2026Public COA archive with ILS provider verification
The public COA library links vendor-hosted PDFs. Most reviewed certificate origins carry exact ILS provider tokens and client matches that readers can open on portal.ils-lab.com; a small remainder is retained only as vendor-certificate links and is not treated as provider-verified. Safety-panel depth is strong on the current set (HPLC, identity, endotoxin, sterility, and often heavy metals / net content). A few library UI labels name other labs while the PDF itself is ILS — the PDF/provider route is the source of truth.

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.
