Arctic Lab Supply Review: Pricing, COAs, and Five Historical Mismatches
Arctic Lab Supply review, updated October 29, 2026: five new Freedom Diagnostics reports, expanded lot coverage, current partner-code and shipping terms, with historical mismatch receipts preserved.
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 failed them in the September review, 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. At the September 18 review, PeptideBenchmark had no affiliate, referral, coupon, sponsorship, or paid-placement relationship with Arctic Lab Supply. A disclosed partner relationship was added October 29, 2026; current terms are described below. The vendor sells research-use-only products; this is a commercial-transparency and documentary-evidence review, not human-use guidance or medical advice.
Update — October 3, 2026 (UTC): Arctic now lists 22 research products and the same 54 pack choices. Reconstitution solution is unavailable on a documentation hold, and the spray bottle is no longer offered. The five historical Chromate images discussed below have been removed from the public archive; each original image URL now returns not found. Their original September receipts and exclusion remain on record. Removal is a publication change, not proof that the historical mismatch was resolved. The catalog and price observations below describe the September 18 review; check the storefront and dated pricing board for current offers.
Update — October 29, 2026 (UTC): The live library publishes 12 current reports for 11 research products, including five new Freedom Diagnostics reports dated October 15: BPC-157 10mg, GHK-Cu 100mg, KLOW 80mg, Tesamorelin 10mg and a second independent report for Retatrutide 10mg lot RT-2502-A. Each new vendor PDF matches the laboratory’s exact document and named client, product and lot. Together with the seven ILS and four historical Janoshik reports, the accepted set is 16 reports covering 11 of 22 research products. The five historical mismatches remain excluded.
ILS still returns matching report details, but it now disables laboratory PDF downloads. The unchanged vendor PDFs retain their archived exact laboratory confirmations; these are distinguished from newly downloaded laboratory documents. New Freedom reports include HPLC purity, LC-MS identity, net content and endotoxin results. A report for one lot does not establish every later vial’s identity or condition.
Current commercial terms: Arctic Pro has ended. The shipping policy now states U.S. and selected international destinations, with restrictions checked at checkout. Free USPS Priority shipping on U.S. orders starts at $149 after coupon and promotion discounts. Arctic advertises same-day dispatch for orders paid by midnight ET, with Sunday USPS scans on Monday. Its shipping-refund guarantee is separate: orders by 6 PM ET are due to ship by the next business day, subject to the policy’s exclusions. These are vendor-stated terms, not independently measured fulfillment performance.
Affiliate update, October 29: PEPTIDEBENCHMARK is a valid partner code. The live store currently returns 0% off during BOGO, preserving attribution while eligible orders receive free matching vials. The emailed usual 25% offer, excluding Arctic Gear, is not the current verified discount and is not applied to comparison prices. The advertised BOGO ends November 1 at 7:59 PM ET, caps free matching vials at five, and excludes Gear, kits and reconstitution solution. Check current coupon terms. PeptideBenchmark may earn commission.
Historical findings below — September 18, with the dated October 3 follow-up. Their counts, missing-report list, accessory availability, membership and shipping observations describe those dates; the October 29 update supersedes them as current-state guidance.
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 historical images failed that check in September: their shared Chromate job/access pair identified MOB Peptides / GHK-Cu 50mg. Those images were removed by October 3, 2026. PeptideBenchmark retains the source fingerprints and discrepancy in its review ledger, with the original observation dates, while excluding the removed images from public certificate records and Arctic evidence.
What we found in the catalog
On September 18, Arctic Lab Supply published 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.
That September catalog included single-compound research vials, blends, and two support supplies. Reconstitution Solution and the empty Spray Bottle accounted for the two non-peptide records. By October 3, reconstitution solution was unavailable on a documentation hold and the spray bottle had been removed; all 22 research-product identities and 54 pack choices remained.
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 rows disagreed across those surfaces in the September 18 review: Semax displayed $29.99 but resolved to $39.99, while one KLOW single-vial row and six KLOW/NAD+ pack rows resolved slightly below their displayed amounts. On October 3, Semax displayed and resolved to $29.99; the other seven reviewed price differences remained. PeptideBenchmark publishes the checkout-resolved prices and checks each remaining difference against its exact reviewed price pair. Mixed-product requirements can be modeled in the Stack Builder.
At the September review, Arctic advertised a paid Arctic Pro membership with a 10% benefit. Arctic Pro has since ended, confirmed on the current FAQ on October 29; no membership discount is applied.
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.
The September follow-up then 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 had no published lot report at that check; the October 29 update above adds matching reports for four of those products.
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
In the September review, five additional images in Arctic’s historical archive carried different displayed product identities but reused the same Chromate credential: job 22761 / access code MOB8AFU8AL3Q. They also reused the same chromatogram. All five were absent from the public archive and returned not found in the October 3, 2026 recheck.
The laboratory-controlled record checked in September identified MOB Peptides as the client and GHK-Cu 50mg as the product. It did not identify Arctic Lab Supply or the products displayed on the five images then hosted by Arctic.
That conflict failed the provider-identity check. The subsequent removal does not resolve the original mismatch. 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]. On September 18, the shipping page stated free standard shipping at $99 and conflicted on geographic scope: some sections say U.S.-only, while another describes worldwide shipping with exclusions. That historical wording is superseded by the October 29 policy check above; confirm current 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.
What this review does not claim
- No binary “safe / unsafe” or “legitimate / illegitimate” verdict
- No endorsement of human use
- No claim that 11 documents cover all 24 base products or every pack choice
- No credit for the five historical Chromate images whose exact credential identified a different client and product in the September review
- No conclusion about why those five mismatches exist
- The original September review preceded the disclosed October 29 affiliate relationship; neither changes the evidence findings

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. The October 29 evidence set contains 16 reports under Arctic Lab Supply: five new Freedom reports, seven ILS reports with archived confirmations and current matching laboratory details, and four historical Janoshik reports. Five historical images failed that identity check in September and were removed by October 3, 2026; their original receipts remain excluded from 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. The October 29, 2026 check found 12 current reports for 11 products: five Freedom Diagnostics and seven ILS Laboratories reports, plus four historical Janoshik reports. Freedom reports resolve at the laboratory. ILS now disables PDF downloads; matching public report details and unchanged vendor PDFs preserve the archived confirmations. The historical Janoshik routes still resolve. 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?
The October 29, 2026 evidence set contains 16 accepted reports covering 11 of 22 research products: five new Freedom reports, seven ILS reports with retained archived confirmations, and four historical Janoshik reports. Report count and product coverage differ because some reports cover an already documented product.
What is the issue with the five historical Chromate images?
In the September review, five images hosted by Arctic reused Chromate job 22761 and access code MOB8AFU8AL3Q. The exact laboratory record identified MOB Peptides / GHK-Cu 50mg. An October 3, 2026 check found those images removed from the archive and all five source URLs returning not found. PeptideBenchmark retains the original dated mismatch receipts without inferring how the discrepancy happened. Removal does not establish that the mismatch was resolved.
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?
There was no relationship at the original September 18 review. PeptideBenchmark became a disclosed partner on October 29, 2026. PEPTIDEBENCHMARK is valid, but its live validation currently returns 0% off during BOGO and preserves partner attribution; the emailed 25% benefit is not applied to comparisons. This changes neither scoring nor the historical findings.
