Is Arctic Lab Supply legit?
Arctic Lab Supply scores 6.98 out of 10 (Fair, #34 of 100) as of November 6, 2026 and passes our testing gate: 16 of the 26 products we score carry a certificate, 16 confirmed with the issuing lab (labs we grade A to B+). Its strongest area is shipping and refunds (10.0/10); its weakest is operating history (2.0/10), with just under a year of records.
On lab evidence, the heaviest-weighted factor, Arctic Lab Supply has independently verified third-party COAs, with COA work on record from Freedom Diagnostics Testing, ILS Laboratories. Its lowest price per milligram in our data is on NAD+ (see the table below).
How this score was calculated
Every point below follows the published tables in our methodology, with the policy wording we scored and a link to where we read it. Evidence last checked October 22, 2026. Lab credibility is worked product by product from the certificates on file.
Lab credibility6.0/10
Each carried product (lab supplies excluded) is scored from the certificate on file for it, on the published lab rubric: 3 for a published certificate, then points for the laboratory, the verification key, the tests on the certificate and its purity, held to 0 to 10. A certificate that is self-issued, names no laboratory, or comes from a laboratory whose independence is not established scores a flat 2.0; a product with no certificate, a certificate the laboratory’s own record fails, or a posted copy that differs materially from the laboratory’s copy scores 0. Calculated on , the day this page was built; the date each certificate was tested is shown on its row.

Weighted mean of 26 products (7 non-core products without a certificate counted at half weight): 136.0 ÷ 22.5 = 6.044.
No adjustments.
6.044 = 6.044, rounded to 0.1: 6.0/10.
Testing gate: 16 of 26 products have a certificate from a directory laboratory (not tier D, not self-issued) with the key confirmed at the laboratory. That is at least half, so the vendor counts as third-party tested and no cap applies.

Lab evidence re-checked on 2 November 2026 after the company published new reports. All 20 current reports on its report page were confirmed at the issuing laboratory (13 Freedom Diagnostics, 7 ILS Laboratories), adding certificates for MOTS-c, NAD+, ipamorelin, semax, semaglutide, tirzepatide, TB-500 and IGF-1 LR3. Nine products newly offered as pre-orders have no report yet and count as uncovered under our coverage rule, and where a product has several reports the newest is scored. Certificates now cover 16 of the 26 products we list, so the testing cap no longer applies. Lab 4.5 to 6.2.

Pricing recomputed on 24 October 2026: listings added for newly reviewed vendors moved the market median for the same products: pricing 8.2 to 8.3.
- Audit · 6.19to6.16
Pricing recomputed on 23 October 2026 under the revised rule E1 (standing offers), which prices a size at the lowest total a buyer can pay without a code under standing prices, so a standing offer that includes a second vial at no extra cost now counts at all the milligrams received, in the vendor's own price and in the market medians for the same products: pricing 8.4 to 8.2.
- Audit · 5.97to6.19
Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 4.1 to 4.5. Note added 22 October 2026: a score on this entry was corrected from 5.96 to 5.97; it had been rounded down instead of half up. Note added 22 October 2026: a score on this entry was corrected from 6.18 to 6.19; it had been rounded down instead of half up.
- Audit · Verified, no change
Re-scored on 22 October 2026 under version 2 of our published rules. No score change. The testing gate is now computed from the certificates instead of set by hand: 8 of 17 products have a certificate from a directory laboratory with the key confirmed at the laboratory, fewer than the half required, so the testing cap applies; the cap sits above the weighted score, so it does not lower it.
- Audit · 5.93to5.97
Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 9.0 to 10.0, pricing 8.8 to 8.4, operating history 3.3 to 2.0, transparency 7.8 to 7.0. Note added 22 October 2026: a score on this entry was corrected from 5.96 to 5.97; it had been rounded down instead of half up.
- Audit · 6.10to5.93
Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: ILS Laboratories, which issued certificates relied on here, does not publish ISO/IEC 17025 accreditation, so the accreditation point no longer applies. Lab 4.4 to 4.1. Note added 22 October 2026: PJLA's register lists ILS Laboratories' accreditation (certificate L25-631) as suspended from 22 October 2026; the accreditation point still does not apply (check L6).
- Audit · 6.11to6.10
Tenure 3.5 to 3.3. The domain was registered in October 2025, so the operating-history score was aligned to its age. Lab and the other subscores are unchanged.
- Audit · 8.03to6.11
Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 8 of the 17 products we list that the vendor offers for sale. Lab 7.9 to 4.4.
- Audit · 7.93to8.03
Correction: our earlier note that three of the seven verification links on the vendor's site were cut short was wrong; the site links all seven in full, and the truncation was in our own checking. That note did not affect the score and has been removed. Separately, the vendor added a US delivery guarantee that refunds shipping if delivery runs late, so shipping rose 8.5 to 9.0.
- Audit · 7.42to7.93
Vendor disputed three points. Shipping and processing upheld in their favour because the policy changed: free US shipping above an order minimum with no membership and a 24-hour dispatch commitment replaced membership-gated free shipping and no stated processing time, so shipping rose 7.0 to 8.5. The verification-link finding was not upheld; investigating it confirmed all seven certificates at the laboratory, so lab rose 7.6 to 7.9. Transparency rose 7.0 to 7.8 for the dated public corrections log.

lab 7.6 / shipping 7.0 / pricing 8.8 / tenure 3.5 / transparency 7.0. Subscores re-derived from the live site; total matches the earlier assessment.
Editor’s notes
Arctic Lab Supply tests through ILS Laboratories and Freedom Diagnostics Testing. PJLA's register lists the ILS accreditation under ISO/IEC 17025 (certificate L25-631) as suspended from 22 October 2026, and Freedom Diagnostics publishes none, so neither earns an accreditation point. In October 2026 we confirmed every one of its seven ILS certificates at the laboratory itself rather than taking the posted copies on trust. All seven resolve to the lab's own record and match on lot and purity, with the lab naming Arctic as the client and holding a photograph of the vial and the chromatogram. The panel is better than most here, covering identity, purity, net peptide content and endotoxin, and the blend we checked reported over its label content. Lots are per product rather than one lot standing behind the whole range. At our 8 October 2026 check, lot-matched certificates covered 7 of the 22 products on the site, and the site said so plainly rather than implying everything is tested. At our October 2026 audit, pricing was below the market median on nearly every compound, by roughly 15%. At our 22 October 2026 check, shipping was free on US orders above an order minimum, the shipping page guaranteed dispatch by the next business day or a refund of the shipping charge, and damaged, wrong or lost orders reported within 48 hours of delivery were reshipped free or refunded in full. Orders go out from Anchorage with tracking. The company keeps a dated public log of corrections to its own documentation, including removing five report images in September 2026 that had been shown with products they did not belong to, and crediting the outside reviewer who spotted it. Very few vendors publish anything of the kind; it is noted here in their favour but is not a scored item, and the underlying mix-up is part of the record too. Semaglutide is listed under the coded name Sema RUO. The domain was registered in October 2025. On 2 November 2026 the company's report page listed 20 current reports for 19 product sizes, 13 from Freedom Diagnostics and 7 from ILS Laboratories, and we confirmed all 20 at the issuing laboratory: each Freedom file is identical to the laboratory's own copy, and each ILS key returns the same lot, date and purity. They cover 16 of the 26 products we list. Nine products newly offered as pre-orders, shipping by 13 November 2026, and CJC-1295 have no report yet; the store says pre-order lots are tested on arrival. Where a product has more than one report we score the newest, so BPC-157, GHK-Cu and retatrutide are now scored from their October Freedom Diagnostics reports.
