Weighted factor result: 8.9/10, rounded to 9/10 on our half-point scale.
Direct answer
Yes. Zen Aminos is an established New Hampshire research supplier with a substantial laboratory-report archive and a 9/10 PeptidePrices evidence score. We matched 170 vendor-attributed reports to specific official laboratory records and retained every page of the 198-report archive. Its 47 compared single-vial, blend and spray offers have 33 exact current certificate controls. The storefront serves the United States and Puerto Rico.
Evidence summary
Zen Aminos earns a 9/10 evidence score from its substantial issuer-matched archive, complete analytical reports, public policies and documented customer-review record. PeptidePrices retains 198 report sets and 33 exact current certificate controls across the 47 compared offers. Current mismatched links, absent issuer identifiers, supplier-attribution questions and report-field conflicts remain identified individually.
PeptidePrices checked the Zen Aminos catalog on October 3, 2026. The comparison includes 47 single-vial, blend and research-spray offers, all available in the retained source snapshot. Reduced-fill material with an unclear nominal amount, encapsulated products, cosmetics, accessories and solutions labeled only by volume remain separate.
The public COA archive yielded 237 complete source files and 198 report sets across 252 retained pages. 170 vendor-attributed reports match specific official laboratory records, and 33 of the 47 compared offers have exact current certificate controls. Twelve report identifiers are absent from Freedom’s official index, fourteen reports name another submitter, and two retain field conflicts. Matrix-K 70 mg has no issued current control. The TB4 primary/endotoxin documents label 10 mg while the mass-spectrometry sample says 5 mg; a historical Horizon Retatrutide 15 mg original and official record show different analysis dates. The Zen Juice 60 mg page links to a Tirzepatide 20 mg report, and the KPV 30 mg page links a 10 mg report. Those discrepancies receive no exact listing certificate.
The analytical documents show what each laboratory actually tested. Freedom’s current BPC-157 10 mg report, reported September 13, lists LC-MS identity, HPLC-UV purity of 99.12% and measured content of 12.83 mg. The October 1 Tesamorelin/Ipamorelin 13 mg Kovera set adds endotoxin and fentanyl screening to identity, purity and content: 99.784% purity, 13.99 mg measured content and endotoxin below 0.06 EU/mL. All seven pages are retained, including the primary certificate, mass-spectrometry material and separate endotoxin result. Those five tests belong to that report; they are not assumed for every archived batch.
The retained archive spans August 22, 2025 through October 1, 2026: 176 Freedom Diagnostics reports, 15 Horizon Analytical reports and seven Kovera report sets. Older reports remain searchable by compound, strength, batch and laboratory alongside the current reports. For example, the current MOTS-c 40 mg Kovera report records 99.658% purity, 41.44 mg measured content and endotoxin below 0.07 EU/mL. Current listing controls select the report linked by the exact single-vial product page, while the archive preserves earlier batches, unresolved supplier attribution and conflicting records as separate evidence states.
The exact branded Trustpilot profile showed 4.6/5 from 66 reviews on October 3. Positive reviews describe delivery, packaging and customer support. A July 9 critical review reports inconsistent CJC-vial clarity and unanswered questions; Zen replied publicly. Finnrick states that it had no published independently purchased Zen Aminos test results as of its August 26 snapshot. These customer-review and independent-testing scopes remain separate from vendor-submitted COAs.
Zen Aminos shipping policy says orders are processed within one business day, with fulfillment beginning at noon Eastern on weekdays. Transit begins after processing. The October 3 cart offered UPS two-day shipping for $14 or overnight shipping for $50, with country options limited to the United States and Puerto Rico. The refund policy makes shipped sales final except damaged, incorrect, missing or confirmed fulfillment-error orders; approved resolutions can include replacement, credit or refund.
The storefront identifies Zen Aminos LLC, New Hampshire-based fulfillment, public email and telephone support and weekday support hours. The public archive retains named laboratory clients, report identifiers, batches and measured results. Some autogenerated product COA strips differ from the newer product description or nominal strength; those discrepancies remain visible in the report-specific evidence.
