High Purity Standards
Peptides produced to defined purity specifications to support reproducibility and reliability. Our release specification is ≥98% purity, verified per lot before distribution.
For research use only. Not for human or veterinary use.
Batch-tested, CoA-verified compounds for laboratory and investigational research. Purity you can prove.
Why Vantriq Labs
Peptides produced to defined purity specifications to support reproducibility and reliability. Our release specification is ≥98% purity, verified per lot before distribution.
Each lot is individually identified and evaluated. Full CoA documentation ensures consistency, traceability, and a verified quality record across every order.
Clear labeling, transparent disclosures, and strict research-only distribution policies are built into every product. All compounds are supplied for research use only.
Quality Assurance
Every batch is independently tested by accredited laboratories. We don’t ask you to take our word for it — we give you the proof.
Every vial is tested to confirm it contains exactly what the label says — down to the microgram. Concentration is quantified against certified reference standards.
Why it matters: No guessing games. You get the exact concentration you paid for, every single time.
Purity is measured by peak area integration against the total chromatogram. Related impurities, degradation products, and residual solvents are individually quantified and reported.
Why it matters: A 95% pure compound introduces 5% unknowns into every experiment. Our ≥98% specification keeps your data clean.
All peptides are lyophilized under controlled conditions to remove water activity and prevent hydrolytic degradation. Stability is validated across temperature and humidity stress conditions.
Why it matters: Degraded compounds produce degraded data. Lyophilization preserves structural integrity from synthesis to your lab bench.
Each lot is screened for bacterial endotoxins using Limulus Amebocyte Lysate (LAL) testing and tested for microbial contamination per USP <71> sterility protocols.
Why it matters: Endotoxin contamination confounds inflammatory assays and in vitro models. Every lot must pass before release.
Every production run is assigned a unique lot number with a full Certificate of Analysis. Retention samples are archived for re-testing. Specifications are held constant across all batches.
Why it matters: Reproducible research requires reproducible inputs. Lot-to-lot variability undermines longitudinal studies.
Method: RP-HPLC, C18 column, 220 nm UV detection
FAQ
Everything you need to know about peptide research
Vantriq Labs peptides are released to a specification of ≥98% purity. Purity is measured by reverse-phase HPLC (High-Performance Liquid Chromatography) and confirmed by mass spectrometry. A lot-specific Certificate of Analysis documenting the measured purity is posted on each product page.
A Certificate of Analysis is a document issued by our quality control lab confirming the identity, purity, and concentration of the compound in a specific production lot. It includes the lot number, HPLC purity percentage, mass spec confirmation of molecular weight, and testing date. Each CoA is lot-specific and traceable.
Lyophilized peptides must be brought back into solution before analytical work. A 10 mL bottle of reconstitution solution is included free with every order, calibrated to the compounds purchased. We do not provide reconstitution volumes, concentrations, or protocols. Determining the appropriate diluent and volume for a given experiment is the responsibility of the researcher.
Lyophilized (freeze-dried) peptides should be stored at −20°C in a sealed container, protected from light and moisture. Reconstituted peptides should be stored at 4°C and used within 28 days. Avoid repeated freeze-thaw cycles, which can degrade peptide integrity.
Lyophilized peptides stored correctly at −20°C are stable for 24 months or longer. Stability varies by sequence — peptides containing cysteine, methionine, or glutamine may have shorter shelf lives. Once reconstituted, stability is typically 4 weeks refrigerated.
Orders with all items in stock ship within 24 hours of being placed. Because our peptides are lyophilized, cold shipping is not required for standard transit times. For longer transit or warmer climates, cold pack shipping is available at checkout.
We currently ship within the United States and Puerto Rico.
Yes. We offer preferred pricing for qualified businesses that order in volume. There are no strict minimum order quantities for standard purchases, but tiered discounts apply at higher volumes. Contact us directly for preferred pricing and discounts and we will work with you to set up a professional account.
All sales are final. However, if a product arrives damaged or tests below its stated purity specification upon independent verification by the customer, we will reship the product. Please contact us with your order number and documentation and we will take care of it.
You can reach our team through the Contact page on this website. We respond to all inquiries within one business day. For order-related questions, please have your order number ready.
