REFERRAL OFFER
Affiliate link active via referral link
PeptideBenchmark referral attribution uses /ref/XVVXY/. The dashboard code XVVXY is part of that link, not a confirmed checkout coupon. No referral-specific customer discount is applied to Pricing or Stack Builder. Partner commission is 20% on a referred customer’s first order and 10% after that, plus a free peptide for PeptideBenchmark every 3 referred orders. Those terms are not shopper savings.
PeptideBenchmark has a disclosed affiliate relationship with Zeptix Labs. This does not change benchmark scores or trust ratings — it only affects outbound links and pricing-board discount modeling where applicable.
Readers who want a short U.S. catalog with house GLP codes mapped on the pricing board and a public certificate library that includes laboratory-hosted Freedom reports.
Vendor-stated: Zeptix Labs LLC, 7901 4th St N STE 300, St. Petersburg, FL 33702. Orders placed before 6 PM Eastern ship the same business day, with free shipping over $200. Support hours are weekdays 9am–5pm Eastern. Observed September 24, 2026.
GLP-1 S, GLP-2 T, and GLP-3 R are house codes for semaglutide, tirzepatide, and retatrutide. The BPC-157 and TB-500 blend was out of stock on the review date. PeptideBenchmark’s referral link records the visit and does not take a percentage off the ranked price. WELCOME15 and the spin-wheel discount are the vendor’s own promotions and are not applied.
A St. Petersburg, Florida research storefront with public variation prices and a public certificate library whose Freedom Diagnostics reports and Accumark Labs AccuVerify pages resolve under the Zeptix Labs client.
Zeptix Labs lists single-vial research peptides, including the house codes GLP-1 S, GLP-2 T, and GLP-3 R. The public COA library publishes a certificate PDF for many listed strengths. PeptideBenchmark uses the regular list price. As of September 24, 2026, PeptideBenchmark has a referral link that does not change that price. The vendor’s WELCOME15 offer and spin-wheel discount are still not applied.
The public COA library hosts certificate PDFs. Freedom Diagnostics reports and Accumark Labs AccuVerify pages resolve under the Zeptix Labs client. Freedom reports support identity, HPLC purity, and net content, with endotoxin and microbial results on some of those reports. Accumark pages support identity and HPLC purity. A strength-specific report is not treated as testing every other strength.
This vendor is one of 130 names currently included in our manual curated research-vendor layer.
This is the strongest public transparency pattern on the site. The key signal is that readers can leave the vendor domain and inspect reports or verification pages on an outside provider domain without needing to log in.
- Treat the outside provider route as the strongest part of the evidence, not the vendor marketing copy around it.
- Look for repeated product-level behavior across the catalog, not just one showcase example.
- Do not overread it as proof that every current lot is covered or current unless the linked report trail itself supports that.
This vendor makes the most sense when you compare it to other vendors using a similar transparency model, rather than to every vendor on the board at once.
PB Curated Assessment is a PeptideBenchmark-authored rubric built from the trust and transparency review layer. It is separate from the source-derived benchmark score.
Zeptix Labs is currently one of the strongest curated cases on the site because readers can inspect a repeatable public evidence trail without logging in.
Readers can leave the vendor marketing layer and inspect verification publicly.
This is the strongest public pattern because the verification step routes into an outside provider layer.

PB score is the number you should read first on this page. It starts with trust evidence, pricing coverage, and third-party review signals from Finnrick, Peptide Critic, Trustpilot, and Pep Review Pro when available. Reviewed transparency evidence contributes a bounded amount — shown as a trust lift for source-benchmarked vendors, and folded into the base score for PB-evidence vendors.
This vendor’s score is evidence-first: verifiable testing evidence forms the backbone, and outside review sources are a bounded adjustment that can warn far more than it can boost. The terms below sum to the displayed score (small rounding aside). Full formula on the scoring methodology page.

METHODOLOGY
How to read this benchmark
This profile summarizes public benchmark data synced from Finnrick and, when available, Peptide Critic. Finnrick contributes a 10-point average from its vendor table, while Peptide Critic contributes a 5-star rating that we normalize to a 10-point scale before ranking consensus entries.
A high score can be directionally useful, but it is not a substitute for current COAs, identity testing, chain-of-custody details, or your own due diligence. We are intentionally separating source aggregation from first-party editorial claims.
Scores combine PB trust evidence with external signals from Finnrick, Peptide Critic, Trustpilot, and Pep Review Pro when available.
