Weighted factor result: 7.6/10, rounded to 7.5/10 on our half-point scale.
Direct answer
Nexa Labs earns 7.5/10 with ten complete verified laboratory reports and a confirmed 10% code. The archive includes ILS Laboratories, Freedom Diagnostics, MZ Biolabs and Krause Analytical testing. Finnrick independently identifies Nexa as the source of both GHK-Cu samples. Ten of 11 current strengths have matching certificates. The remaining GLP-3R file has only one of three pages and no published Finnrick match. IGF-1 LR3 measures 0.89 mg against its 1 mg label. Nexa names its LLC but publishes no street address; checkout accepts credit/debit cards, Venmo and Zelle, with $10 flat-rate shipping and free shipping over $200.
Evidence summary
Nexa Labs earns 7.5/10 overall. Ten complete verified reports and both passing independent Finnrick GHK-Cu tests support its COA score. The unresolved GLP-3R file, IGF-1 LR3 shortfall and limited company address and customer history remain material.
The current Nexa certificate archive contains 11 distinct report sets, checked October 7, 2026. PeptidePrices retains ten complete verified reports across 22 pages, plus the available first page of the unresolved GLP-3R report. The complete files include ILS Laboratories, Freedom Diagnostics, MZ Biolabs and Krause Analytical reports commissioned through Finnrick. All current storefront certificates are represented in the COA library.
ILS Tesamorelin reports identity, 99.17% purity, 10.38 mg content and no detected fentanyl at its 50 ng/mL cutoff. Freedom reports BPC-157 at 99.20% and 10.19 mg, IGF-1 LR3 at 99.01% and 0.89 mg, and Melanotan II at 99.82% and 11.47 mg. Krause reports GHK-Cu 50 mg at greater than 99.9% purity and 52.6 mg, and GHK-Cu 100 mg at greater than 99.9% and 114 mg. Four complete MZ reports show identity and purity: CJC-1295 no DAC/Ipamorelin 99.80%, GLOW 99.98%, Semax 99.94% and BPC-157/Thymosin beta-4 99.88%. The MZ peak-area percentages do not measure component mass. The Krause methods pages describe endotoxin and metals assays without publishing measured results for those tests.
Ten of the 11 single-vial offers have exact matching complete certificates. The MZ chromatogram filenames identify the blend totals; product labels supply their compositions. The remaining GLP-3R certificate extwr3v reports 99.93% purity and 9.55 mg, but only its first of three pages is available. Finnrick returned no published match when rechecked on October 7, so its laboratory verification and vendor attribution remain unresolved. IGF-1 LR3 separately measures 11% below its 1 mg label.
Finnrick identifies Nexa Labs on the specific records for GHK-Cu 50 mg and GHK-Cu 100 mg. Both reports match their certificate IDs, Krause laboratory numbers, strengths, identity, purity and measured content. Finnrick says members of the public submitted the samples. Its Nexa vendor page displayed an 88% analytical rating, third among 457 ranked vendors, from two passing GHK-Cu tests on October 7. That small analytical sample is separate from customer delivery reviews.
The public terms identify Nexa Labs LLC and apply Missouri law. The contact page supplies email without a company street address or founding date. No established independent customer-review total was found for the exact storefront. Similarly named software companies and stores are excluded from Nexa’s reputation evidence.
Nexa advertises dispatch within 24 hours and free shipping over $200. The October 7 US checkout quoted $10 flat-rate shipping and defaulted to $5 optional insurance. Credit/debit cards, Venmo and Zelle were confirmed at checkout. PEPTIDEPRICES reduced $50 merchandise to $45. The refund policy makes sales final and generally limits authorized exceptions to credit, with a 15% restocking fee. The terms separately promise a full refund if Nexa cancels a pricing-error order.
