Most peptide vendors publish one number: purity. Nexa Verified™ is the industry's higher bar — independent ISO 17025 testing, the full safety panel, and a Certificate of Analysis built for the people who actually read it.
Tested for purity, identity, and safety on every batch.
The peptide industry is exploding. New brands are launching every month and most of them publish purity testing only. That tells a consumer how much of the powder is the target peptide — and nothing about what else might be in the vial.
Bacterial contamination, endotoxins, residual solvents, and identity confirmation are invisible to a purity-only test. People are injecting these products. They deserve to know more.
Nexa Verified raises the floor. A fuller test panel, an independent ISO 17025 partner lab, a Certificate of Analysis a normal person can actually read, and a recognizable badge that signals it was done right.
Methods used by partner ISO/IEC 17025 accredited laboratories. Each result is reported on the COA in plain English alongside the underlying data.
Mass spectrometry confirms the powder is the exact peptide claimed on the label — not a similar one, not a partial chain.
HPLC with UV detection measures exactly how much of the powder is the target peptide vs. trace by-products of synthesis.
Visual inspection. Color, texture, and consistency of the lyophilized powder — the first signal of degradation or off-spec product.
Confirms the peptide fully dissolves at the stated concentration. Cloudy reconstitution is an early warning of degradation.
Even if a product is sterile, dead-bacteria fragments can trigger fever and immune reactions. LAL assay catches them at parts-per-billion.
Counts viable bacteria per gram. The strict threshold means the product is effectively sterile under normal handling.
Fungal contamination check. Mold and yeast can survive where bacteria can't and can produce their own toxins.
Trifluoroacetic acid is a residual solvent from peptide synthesis. 19F NMR quantifies it to ensure it's below safe thresholds.
You make great peptides. We make sure customers can trust them. Here's how the Nexa Verified process works.
Send us a sealed sample from the batch you want certified. We provide the chain-of-custody paperwork.
Our ISO/IEC 17025 partner lab runs the full Nexa Verified panel — identity, purity, safety, and stability.
Pass? You receive a Nexa Verified Certificate of Analysis with a unique batch QR code customers can scan to verify.
Use the Nexa Verified badge on your packaging, product pages, and marketing. We provide the assets.
Nexa Labs partners with an independent ISO/IEC 17025 accredited laboratory operating from an FDA-compliant facility equipped with the full analytical stack required for peptide testing — HPLC, mass spectrometry, LAL assay systems, microbiological culture suites, and 19F NMR.
Our partners have spent years in the peptide industry. They know the difference between catalog peptides and clinical-grade material, between a passing COA and a defensible one.
You get the rigor of an established lab and the consumer-readable presentation of the Nexa Verified standard. The science is theirs. The trust mark is ours.
FDA-compliant indicates that the lab operates in accordance with applicable FDA standards and good laboratory practices. FDA-compliant is distinct from FDA-certified or FDA-approved. Nexa Verified is a private certification program operated by Nexa Labs.
Nexa Labs does not manufacture peptides. Our partner labs have no commercial interest in the products they test.
Every test method on the COA is documented, validated against reference standards, and traceable to a calibrated instrument.
Each batch is tracked by lot number. The QR code on the COA links to that specific batch's full report — every time.
Samples from every certified batch are retained by the lab so results can be re-verified or audited if questioned.
The peptide industry is exploding and a lot of new founders are scrambling to figure out how to do this legally, safely, and in a way that won't blow up later. We've done the work. We'll show you the path.
Equipment selection, facility layout, SOPs, GMP-aligned manufacturing processes, vendor sourcing for raw materials, and quality-control workflows. We help you stand up a lab that won't fail an inspection.
State licensing, registered agent setup, FDA facility registration, DEA considerations, labeling requirements, and the legal scaffolding required to operate a compounding or research-supply business.
Brand identity, product photography direction, e-commerce setup, COA hosting, customer-facing copy, and the SEO foundation. Built to convert and built to satisfy a payment processor's review.
Introductions to telehealth platforms, prescriber networks, and the regulatory framework around legitimate medical pathways. We help you build a compliant prescription distribution channel.
Consulting engagements are scoped and priced per project. Tell us where you are and where you want to be — we'll build a roadmap.
Years of combined experience across analytical chemistry, peptide manufacturing, regulatory affairs, and brand strategy. We've been in the industry. We know what the gaps are. We're building the bar everyone should be held to.
Brand strategy and industry partnerships. The voice behind the Nexa Verified standard and the bridge between the lab and the market.
Years of analytical chemistry and peptide manufacturing experience. Oversees the relationship with our ISO 17025 testing partners.
Regulatory, licensing, and end-to-end launch experience. Leads consulting engagements for brands entering the peptide industry.

The Nexa Verified Certificate of Analysis is built so a consumer can read it in 30 seconds, a brand can hand it to a customer with pride, and a chemist can still verify every method against the raw data.
On the product page or the packaging. The gold checkmark seal is your shortcut — every certified product carries it.
Every Nexa Verified COA has a unique QR code per batch. Scan it to verify online that the report is real and current.
You shouldn't need a chemistry degree to know what you're putting in your body. Every test on the COA is explained.
If you have a Nexa Verified product, every batch has a unique lot number printed on the vial label and on the QR code. Enter it below to pull the certificate.
