A compact public catalog with branded GLP naming (SLP-2, SLP-3) and core peptide coverage. The current product galleries expose 56 certificate records across 33 of 38 products in the certificate review, representing 50 distinct destination URLs. Of those, 38 are provider-verifiable relationships: ILS relationships carry report-specific links, Kovera relationships resolve at koveralabs.com, and Freedom relationships resolve at Freedom Diagnostics. Averaged purity runs ~99.7% with unusually broad safety panels — HPLC, identity, heavy-metals, endotoxin, and sterility.
Readers who want branded GLP labels mapped on the pricing board plus third-party certificates with report-specific ILS references and lab pages reopened at Kovera or Freedom, alongside deep safety panels — heavy-metals, endotoxin, and sterility — across the core catalog.
Coverage now reaches 33 of 38 catalog products, but 18 gallery relationships cannot currently be checked beyond Silverstone's own site. Confirm the exact certificate and batch for the SKU you are evaluating.
