Evidence summary
Arctic Lab Supply COAs and evidence
Arctic Lab Supply earns the owner-set 8.5/10 from COA 8, reputation 8, transparency 9 and operations 9.5. All 11 reports match genuine laboratory originals. Seven have complete result agreement; four ILS PDF/web metal inconsistencies remain visible without a failed printed laboratory limit. Three of 22 current strengths have eligible listing controls. Historical below-label content and dated independent shipping complaints remain in the review.
01
Complete archive and verification
PeptidePrices reviewed the complete Arctic archive: seven current ILS Laboratories reports and four historical Janoshik reports. The 18 visible Newest/All cards resolve to 11 unique report identities and 16 report pages. All 11 match genuine laboratory originals and name Arctic as the client. Seven agree across original files and complete web records. Four current ILS-issued PDFs have different metal results from the laboratory’s current web records. Our October 8, 2026 review preserves their authenticity verification and records the result differences separately.
02
Issued PDFs versus laboratory web records
The four laboratory source inconsistencies concern GLP-3R 10 mg and 20 mg, BPC-157 5 mg and GHK-Cu 50 mg. Both the Arctic-hosted and laboratory-hosted PDFs say Not Detected for every metal. The current ILS web records show measurable concentrations below the stated screening limits. For example, report COA-2026-3WB8HV shows cadmium 0.0782 ppm against a 0.5 ppm limit, chromium 0.0807 ppm against 10 ppm, mercury 0.191 ppm against 1.5 ppm and lead 0.106 ppm against 1 ppm. Its vendor and issuer PDFs are identical byte for byte. The inconsistency is between two laboratory-controlled sources; all displayed metal results pass their printed laboratory screening limits. No numerical metal detection threshold or definition of Not Detected is printed. Both versions remain retained for reconciliation. Authenticity, vendor attribution and quantitative result agreement have separate findings.
03
What the assays measure
All 11 reports list identity, purity and measured content. The seven current ILS reports add a fentanyl immunoassay with a 50 ng/mL cutoff and endotoxin reported at no more than 0.05 EU/mL. No failed printed assay limit was found; the endotoxin results carry no scoring penalty. Four add five-element ICP-MS screening and a PCR microbial screen. The five metals count as one test category. PCR results labeled No Growth are not culture-based sterility tests. ILS identifies these peptides by chromatographic retention time against a reference standard. Its purity figures use RP-HPLC peak-area normalization at 214 nm; non-peptide process impurities are excluded. These reports do not include a separate mass-spectrum identity result. ILS describes its accredited scope and research peptide testing separately in its terms.
04
Coverage of current strengths
Current reports cover seven of the 22 advertised compound/strength choices. Three current strengths have a report that passes our complete issuer comparison: GLOW 70 mg, Melanotan-1 10 mg and Melanotan-2 10 mg. The other 15 strengths have no published exact report, and the four metal-conflict strengths remain without a listing control. Current HPLC purity ranges from 98.07% for Melanotan-2 to 99.90% for GLP-3R 20 mg. GLOW reports 72.88 mg total blend content. Its 52.47 mg GHK-Cu, 10.35 mg BPC-157 and 10.06 mg TB-4 figures are calculated from the total and stated formulation, so we count one content assay. GLP labels stay GLP-1S, GLP-2T and GLP-3R in our public price listings.
05
Historical amounts and lot labels
The four February Janoshik reports are authentic historical evidence. Report 102150 reports 8.78 mg in a nominal 10 mg GLP-3R sample, or 87.8% of its label, with 99.610% purity. Report 102152 reports 46.26 mg in a nominal 50 mg GHK-Cu sample, or 92.52%, with 99.285% purity. These are measured content shortfalls in genuine reports, separate from their purity. Neither recovered historical report states a formal content acceptance threshold, so these measurements remain below-label findings rather than failed printed assay limits. The other historical results are BPC-157 5.71 mg and Melanotan-2 10.85 mg. Older reports stay in the library and do not override the status of later current documents. Two current issuer vial photographs also carry different lot labels from their printed reports: RT2502B versus RT-2502-A, and GHK2502B versus GHK-2501-B.

Customer reviews and company
The Trustpilot profile displays 4.0/5 from 24 reviews on October 7. We read all 24: sixteen five-star, two four-star, two two-star and four one-star reviews. Positive accounts describe pricing, packaging, delivery and helpful answers. Six negative entries describe missing or delayed shipments and communication or refund concerns. A July 31 two-star account reports an address-confirmation problem and unanswered support; July 13 and July 17 one-star accounts report orders not received. Merchant replies to older complaints describe address correction and support changes, with no independently established resolution. The published merchant is Arctic Lab Supply LLC in Anchorage, Alaska, with support hours Monday–Friday, 9 a.m.–5 p.m. Alaska time. The street address in Organization data is a published business address; manufacturing responsibility and operator qualifications were not independently verified. The Facebook business page links the exact storefront domain and displayed 1.2K followers and no reviews on October 8. Its transparency dialog dates the page’s creation to June 7, 2026. Jack identifies Dane as the operator through direct commercial correspondence; the Facebook page did not independently establish a named owner.
