Visit Arctic Lab Supply

Arctic Lab Supply is one of the more transparent vendors we checked, with lot-matched COAs, named labs and below-median prices. As of October 19, 2026, it names its company and city, lists three testing labs and posts COAs by lot code. The main gap is that we found no independent Finnrick tests for it.

Notice: Arctic Lab Supply products are sold for in-vitro laboratory research only. They are not FDA-approved and not for human or animal use. This review covers supplier transparency and prices. We didn't buy or test any products. Some vendors pay us a commission when you buy through our links. That never changes a score or a price ranking.

Testing and COAs

Arctic Lab Supply has a dedicated COA page. Individual reports sit at URLs that pair a product with a lot code, such as retatrutide 10mg lot "rt-2502-a" and GHK-Cu 50mg lot "ghk-2501-b." The site names three labs: Janoshik, Freedom Diagnostics and ILS Lab. It also mentions endotoxin or sterility testing.

These are vendor-commissioned reports, and we did not verify them with the labs. What's missing is outside data: we found no Finnrick tests for Arctic Lab Supply.

What we like

  • Company name (Arctic Lab Supply LLC) and city (San Diego, CA) published.
  • Lot-matched COAs on a public COA page.
  • Three named testing labs, plus a mention of endotoxin or sterility testing.
  • Prices below our index median on most compounds, with retatrutide 60mg 46% below.
  • Free shipping on orders of $199 or more, per its site banner.

What to watch

  • No Finnrick tests found, so no independent record to compare with its COAs.
  • Tirzepatide is 8% above the index median.
  • Payment is limited to Zelle, ACH and Apple Pay.
  • Founding year not published.

How it compares

Arctic Lab Supply discloses more than most vendors of its size, and its prices are competitive. Vendors with Finnrick records give you an outside check that it lacks for now. See all vendors we track, peptide deals this week and our ranked list.

Bottom line

Arctic Lab Supply publishes the basics a buyer should look for: a company name, a city, named labs and COAs tied to lots. Prices are below the median on most compounds. Until independent tests appear, match the lot on its COA to the product you order.
