Every batch independently verified through Janoshik Analytical. Browse sample COAs now. Verify your batch when it arrives.
We sized our vials for extended observation protocols—and our bundles pair complementary compounds. These aren't arbitrary discounts. They're research rewards for evidence-based combinations.
"Research rewards for evidence-based combinations—not arbitrary percentage-off promotions."
Data-driven integrity at every step of the supply chain.
Every batch undergoes independent third-party testing at Janoshik Analytical. HPLC-DAD purity, LC-MS/MS identity, and LAL endotoxin analysis before release.
Split-screen COA reports with immutable watermarking. Dual chromatography data presented side-by-side — tamper-evident by design.
Enter any VX Batch ID to retrieve full verification reports in seconds. No email requests. No wait times. Audit on demand.
Janoshik testing costs $250-350 per product. That's why our pricing is higher than budget vendors. We'd rather show you data than ask you to trust claims.
Generic claims about "98% purity" mean nothing without batch verification. Here's why every batch gets independently tested.
Even under GMP conditions, peptide synthesis produces batch-to-batch variance of 2-5% in final purity. Temperature fluctuations during lyophilization, reagent lot variations, and coupling efficiency differences create measurable purity drift — normal in peptide chemistry, but unacceptable without verification.
Real Example: Batch A tests at 99.1% purity. Batch B from the same manufacturer, same specification, tests at 97.8%. Both labeled "≥98%" — only independent testing reveals the 1.3% difference that affects experimental reproducibility.
Every batch ships with independent Janoshik verification including HPLC purity, LC-MS identity, and LAL endotoxin results. You verify the actual batch you receive — not a representative sample from months ago.

Every Vantix Bio batch is sent to Janoshik Analytical for independent third-party testing. This includes HPLC-DAD (purity quantification), LC-MS/MS (molecular identity confirmation), and LAL endotoxin testing (bacterial contamination screening). Janoshik is the international standard for analytical testing competence.
Every batch is tested using two independent analytical methods — HPLC-DAD for purity and LC-MS/MS for identity confirmation. Results are displayed side-by-side in our Verification Portal with forensic watermarking, providing a tamper-evident audit trail that cannot be fabricated or reused from another source.
A unique alphanumeric identifier assigned to every batch. Enter it in the Verification Portal to instantly retrieve the full analytical report, including purity percentage, identity confirmation, and the laboratory accreditation certificate.
HPLC-DAD measures purity (what percentage is the target peptide). LC-MS/MS confirms molecular identity (is it actually the right compound). LAL endotoxin testing screens for bacterial contamination. Three complementary methods eliminate purity fraud, substitution, and contamination risks — the forensic standard for research-grade verification.
Direct-source synthesis partnerships and batch-level testing economies allow us to absorb analytical costs without inflating retail pricing. We believe forensic verification should be standard, not a premium upsell.
No. All Vantix Bio compounds are sold strictly for in vitro and in vivo laboratory research purposes only under the Research Use Only (RUO) exemption. They are NOT intended for human consumption, diagnostic use, or therapeutic application, and are not approved by the FDA. By purchasing, you certify you are a qualified researcher and will use these materials solely for bona fide research purposes in controlled laboratory settings.
We offer standard USPS shipping (next business day processing, 3-5 business days delivery) and expedited options. All orders are shipped with discreet packaging and include the VX Batch ID for immediate verification upon receipt. Free shipping on orders $150+.
Enter your VX Batch ID (printed on the vial label) into our Verification Portal. The full analytical report displays instantly — including HPLC purity percentage, LC-MS/MS identity confirmation, LAL endotoxin results, and a one-click link to verify directly on janoshik.com (takes you straight to the test results, no manual Task ID entry). We also provide downloadable raw data (chromatograms, mass spectra) for advanced verification. No login required, no email requests, available 24/7.
Lyophilized (powder): Store at -20°C in original sealed vials, protected from light and moisture. Stable for 12-24 months when stored properly. Reconstituted (solution): Store at 2-8°C (refrigerated) for up to 28 days depending on peptide. Avoid freeze-thaw cycles. Published stability data varies by peptide — consult literature for specific compounds. All Vantix Bio products ship with storage recommendations on the product insert.
We are launching in late April 2026. Analytical testing is currently in progress at Janoshik Analytical for our initial 12-product catalog. Once all COA reports are received and uploaded to the verification portal, we will open orders and notify everyone on the waitlist. Join the waitlist on any product page to receive priority notification and founding member access.
Janoshik Analytical is ISO 17025 accredited (Czech accreditation body). But beyond accreditation, Janoshik has become the peptide research community's de facto verification standard due to: (1) publicly verifiable Task IDs that anyone can cross-check, (2) specialized peptide testing expertise spanning 10+ years, and (3) transparent pricing and turnaround times. ISO 17025 proves competence — Janoshik's community recognition proves trust and accessibility.
We accept major credit cards (Visa, Mastercard, Discover, American Express) and ACH bank transfers. All transactions are processed through secure payment gateways with PCI-DSS compliance. We do not store payment card information.
Currently we ship to US addresses only. International shipping introduces regulatory complexity and customs delays that compromise product stability. We are evaluating international fulfillment partners for future expansion but cannot provide a timeline at this stage.
Janoshik-verified research peptides sized for extended observation protocols. Independent triple-method testing on every batch.
