Readers who want a small, US-shipped catalog where the tested products link Janoshik reports that resolve at the lab, plus free domestic shipping on every order.

Fulfillment

Vendor-stated: operating from Washington State; mailing address 522 W Riverside Ave #4462, Spokane, WA 99201; free U.S. shipping on all orders; no international shipping; 21+ research-use gate. Support is email-only at support@cinderpeptides.com / +1 (425) 660-2477. Observed August 3, 2026.

Watch-out

GLP-2 (T) and GLP-3 (R) are branded names for tirzepatide and retatrutide; GLOW is the GHK-Cu / TB-500 / BPC-157 blend at a labeled 70 mg vial total. NAD+, Sermorelin, TB-500, and Tesamorelin were out of stock or still pending public COAs at onboarding. Quantity discounts (up to 20% at 21+) exist on the site but default rankings use the single-vial price. Domain registered May 2026 — a new storefront.

A Spokane, Washington research supplier with a small public catalog, free domestic shipping on every order, and a Lab Results page whose Janoshik Analytical reports check out on the lab's own verify site.

Cinder Peptides keeps a compact research-only catalog — BPC-157, GHK-Cu, GLOW, branded GLP-2/GLP-3 strengths, and a handful of still-building SKUs — with openly listed vial prices and quantity discounts. Its public Lab Results page links Janoshik reports for the tested products; PeptideBenchmark confirmed those reports live at the lab during onboarding.

This is the strongest public transparency pattern on the site. The key signal is that readers can leave the vendor domain and inspect reports or verification pages on an outside provider domain without needing to log in.

  • Treat the outside provider route as the strongest part of the evidence, not the vendor marketing copy around it.
  • Look for repeated product-level behavior across the catalog, not just one showcase example.
  • Do not overread it as proof that every current lot is covered or current unless the linked report trail itself supports that.

This vendor makes the most sense when you compare it to other vendors using a similar transparency model, rather than to every vendor on the board at once.

How to read this benchmark

This profile summarizes public benchmark data synced from Finnrick and, when available, Peptide Critic. Finnrick contributes a 10-point average from its vendor table, while Peptide Critic contributes a 5-star rating that we normalize to a 10-point scale before ranking consensus entries.

A high score can be directionally useful, but it is not a substitute for current COAs, identity testing, chain-of-custody details, or your own due diligence. We are intentionally separating source aggregation from first-party editorial claims.

Scores combine PB trust evidence with external signals from Finnrick, Peptide Critic, Trustpilot, and Pep Review Pro when available.
