Arctic Lab Supply Review: Pricing, COAs, and Five Historical Mismatches
An independent Arctic Lab Supply review covering 24 base products, 78 visible SKU choices, 11 exact ILS and Janoshik verifications, and five historical Chromate images excluded after credential checks.
Arctic Lab Supply is now a curated vendor on PeptideBenchmark. This review is unusually useful because it records both evidence that passes exact provider checks and historical images that fail them, while the public certificate database exposes only the exact provider-bound records. The result is not a blanket verdict: it is a catalog and certificate trail readers can inspect record by record.
Reviewed September 18, 2026. PeptideBenchmark has no affiliate, referral, coupon, sponsorship, or paid-placement relationship with Arctic Lab Supply. The vendor sells research-use-only products; this is a commercial-transparency and documentary-evidence review, not human-use guidance or medical advice.
The short version
We found a public research storefront with:
- standing prices and publicly visible pack choices;
- 24 base product records plus 54 active 2-, 3-, and 5-vial choices — 78 visible SKUs in all, with 76 peptide rows after the two supplies stay off the pricing board;
- house labels GLP-1 (SG), GLP-2 (TR), and GLP-3 (RT) for semaglutide, tirzepatide, and retatrutide;
- a public batch archive with 11 exact provider-verified documents — seven current ILS Laboratories reports and four historical Janoshik Analytical reports; and
- five historical Chromate-image mismatches documented for audit continuity but excluded from the public certificate database and evidence scoring after their credentials resolved to a different client and product.
The current ILS set and four historical Janoshik reports resolve under Arctic Lab Supply through exact laboratory-controlled routes. Five other historical images do not: their shared Chromate job/access pair resolves to MOB Peptides / GHK-Cu 50mg. PeptideBenchmark retains the source fingerprints and discrepancy in its review ledger, while excluding the misleading images from public certificate records and Arctic evidence.
What we found in the catalog
Arctic Lab Supply publishes 24 base product records with standing prices. Eighteen peptide products also expose dedicated 2-, 3-, and 5-vial choices, producing 54 active pack SKUs and 78 visible single- and multi-vial choices overall. After excluding the two supplies, the live Pricing board tracks 76 normalized peptide rows with each pack’s full price, vial count, and total labeled milligrams.
The storefront includes single-compound research vials, blends, and two support supplies. Reconstitution Solution and the empty Spray Bottle are part of the 24-product storefront count but stay outside the peptide $/mg comparison.
House labels matter here:
- GLP-1 (SG) → semaglutide
- GLP-2 (TR) → tirzepatide
- GLP-3 (RT) → retatrutide
The catalog also lists GLOW 70mg and KLOW 80mg blends. Customer-facing product selectors provide the displayed pack choices, while cart and checkout resolve each stored choice to an exact app-catalog SKU. Eight reviewed rows currently disagree across those surfaces: Semax displays $29.99 but resolves to $39.99, while one KLOW single-vial row and six KLOW/NAD+ pack rows resolve slightly below their displayed amounts. PeptideBenchmark publishes the checkout-resolved price for all eight exact SKUs and fails closed if any reviewed pair changes. Mixed-product requirements can be modeled in the Stack Builder.
Arctic also advertises a paid Arctic Pro membership with a 10% benefit. PeptideBenchmark compares the public standing prices and pack choices without applying that subscription-only discount.
The 11 documents that verify exactly
Browse the exact provider-bound records in the Arctic Lab Supply COA results.
PeptideBenchmark confirmed 11 exact laboratory routes under the Arctic Lab Supply client identity:
| Evidence set | Exact provider-verified documents | Status in the reviewed archive |
|---|---|---|
| ILS Laboratories | 7 | Current |
| Janoshik Analytical | 4 | Historical |
| Total | 11 | Current and historical evidence |
The current ILS set covers seven listed product/strength choices: GHK-Cu 50mg, BPC-157 5mg, GLOW 70mg, Melanotan II 10mg, Melanotan I 10mg, GLP-3 (RT) 10mg, and GLP-3 (RT) 20mg. These reports include HPLC purity, identity, endotoxin, and net-content panels; four also report sterility and heavy metals. The four historical Janoshik documents resolve through exact task/key routes under Arctic Lab Supply.
A later check of every public product page and the live batch archive still found no additional certificates. GHK-Cu 100mg, BPC-157 10mg, GLP-1 (SG), GLP-2 (TR), GLP-3 (RT) 30mg and 60mg, CJC-1295 no DAC, Semax, TB-500, KLOW, NAD+, tesamorelin, MOTS-c, IGF-1 LR3, and ipamorelin currently have no published lot report.
That is meaningful coverage, but it is not full-catalog coverage. A provider-verified report documents the named sample and reported panels. It does not prove that every catalog item has been tested, that a later vial comes from the same batch, or that an unreported panel passed.
The five historical Chromate mismatches
Five additional images in Arctic’s historical archive carry different displayed product identities, but all five reuse the same Chromate credential: job 22761 / access code MOB8AFU8AL3Q. They also reuse the same chromatogram.
The laboratory-controlled record for that exact credential identifies MOB Peptides as the client and GHK-Cu 50mg as the product. It does not identify Arctic Lab Supply or the products displayed on the five Arctic-hosted images.
That conflict is enough to fail the provider-identity check. PeptideBenchmark therefore:
- preserves the five source fingerprints and mismatch facts in its review ledger;
- labels the credential, client, and product mismatch plainly in this review;
- excludes the images from ordinary public certificate records;
- awards them no provider-verification or trust credit; and
- does not infer whether the mismatch came from a publishing, production, or other process.
The same rule applies in both directions: an exact credential must bind the document to the claimed client and product before it can strengthen a vendor’s evidence score.
Location and fulfillment claims
Public Organization data identifies Arctic Lab Supply LLC at 10177 Marmot Cir, Anchorage, AK 99515-2347, with support at [email protected]. The shipping page states free standard shipping at $99 but conflicts on geographic scope: some sections say U.S.-only, while another describes worldwide shipping with exclusions. PeptideBenchmark leaves that conflict visible and recommends confirming destination eligibility at checkout. These are vendor-stated terms observed on September 18, 2026, not evergreen guarantees. The Anchorage location appears on the peptide map.

Common questions
Is Arctic Lab Supply legitimate?
PeptideBenchmark does not issue binary legitimacy or product-safety endorsements. Arctic Lab Supply publishes an openly priced research catalog, an Anchorage business address, and a public batch archive. Eleven documents resolve through exact laboratory-controlled routes under the Arctic Lab Supply client name. Five other historical images fail the same identity check and receive no evidence credit. Those facts create an inspectable record; they do not establish the identity, condition, or safety of a physical vial.
Does Arctic Lab Supply publish COAs?
Yes. Its public batch archive currently exposes seven ILS Laboratories reports, and the historical archive includes four Janoshik Analytical reports that resolve through exact task/key routes. PeptideBenchmark records five additional historical Chromate-image mismatches in its review ledger, but excludes those images from the public certificate database and from trust credit because their shared job/access credential resolves to a different client and product.
How many Arctic Lab Supply COAs verify at the laboratory?
Eleven exact documents verified in this review: seven current ILS reports and four historical Janoshik reports. The seven ILS documents cover seven listed product/strength choices, not the full catalog.
What is the issue with the five historical Chromate images?
All five Arctic-hosted images reuse Chromate job 22761 and access code MOB8AFU8AL3Q. The laboratory-controlled record for that exact pair identifies client MOB Peptides and product GHK-Cu 50mg, rather than Arctic Lab Supply or the products displayed on those images. PeptideBenchmark records the mismatch without inferring how it happened and awards the images no trust credit.
What do GLP-1 (SG), GLP-2 (TR), and GLP-3 (RT) mean?
They are Arctic Lab Supply storefront labels. PeptideBenchmark maps GLP-1 (SG) to semaglutide, GLP-2 (TR) to tirzepatide, and GLP-3 (RT) to retatrutide for cross-vendor comparison.
Does PeptideBenchmark have an affiliate relationship with Arctic Lab Supply?
No. At the time of this review, PeptideBenchmark had no affiliate, referral, coupon, sponsorship, or paid-placement relationship with Arctic Lab Supply. The vendor operates a public GoAffPro partner program, but PeptideBenchmark is not representing that program as its own relationship.
