Direct answer

Is Zenith Biopeptides legit?

Yes. Zenith Biopeptides has a substantial independent testing record: its 71 COAs cover repeat batches, with 19 including extended panels. Trustpilot showed 4.5/5 from 37 reviews on November 12, 2026, with frequent praise for delivery and support. The Ohio supplier publishes contact and shipping terms and accepts cards and bank payments. We rate it 9/10 overall. Its detailed reports also document a historical identity failure, low-content findings and two low-purity results.

COA evidenceCOA quality 9.5/10COA verified

The 71-COA archive from Freedom Diagnostics documents repeat-batch identity, purity and content testing. Fifty COAs include endotoxin results and 19 add heavy metals, PCR microbial screening, fentanyl and pH. Sixty-four match official laboratory records. Historical identity and low-content findings temper the otherwise broad testing program. For these reasons, we rate Zenith Biopeptides 9.5/10 for COA practices.

Purity: 97.13%–99.97% across 67 non-water COAs with numerical purity; two COAs report values below 98%.

Customer reviews

Trustpilot shows 4.5/5 from 37 reviews, checked November 12, 2026. Positive reviews frequently praise delivery and support. Two one-star reviews describe an insurance demand and advertising messages. Zenith replied that these appeared to involve impersonators and asked for evidence. The attributed reviews below preserve those different experiences.

Laboratory testing

The official COA library contains 71 distinct COAs after matching nine endotoxin supplements and removing two duplicate downloads. Reports span January 11 to October 19, 2026. Sixty-four COAs match Freedom Diagnostics’ official records, including one GHK-Cu report whose official version corrects the printed client name. Fifty COAs include endotoxin testing; 19 include metals, PCR microbial screening, fentanyl screening and pH. PCR results specifically describe microbial DNA detection.

Material report findings

The historical KLOW 80 mg report dated May 7 prints an identity failure and identifies GHK-Cu, BPC-157 and thymosin beta-4 without KPV. Later KLOW testing identifies all four components, while preserving a 70 mg printed label against the current 80 mg listing. Two historical Selank 10 mg reports measure 5.87 mg and 5.73 mg. The L-carnitine 1200 mg report measures 207.76 mg on average. Seven source COAs, including these findings and the two sub-98% purity reports, return no match in the official search-code lookup. Their full vendor files remain available with neutral labels. The September Selank and October glutathione reports document later batches with substantially different measured contents.

Business identity and history

The About page places the business in Columbus, Ohio. Its contact page publishes a Hilliard mailing-suite address, telephone and support email. Terms name Zenith Biopeptides LLC. The domain registration dates to August 8, 2025. The Hilliard address is a published contact address, with no independent evidence that it is the fulfillment premises.

Shipping, payment and returns

The shipping policy states same-business-day dispatch before 2 PM Eastern and next-business-day processing after the cutoff. The FAQ estimates three-business-day standard delivery, while the About page allows 1–2 processing days. Free shipping starts at $300. Checkout offers credit/debit cards, IDEM card payment, Zelle and ACH. UPS shipping costs $9 with a 2–3-day estimate; Zelle advertises an additional 5% payment-method discount. The return policy generally excludes delivered-product returns, with 14 days to raise quality issues and 48 hours for wrong or damaged arrivals. Verified vendor errors may receive replacement, credit or refund. This is broader than the terms page’s final-sale wording.
