All products sold by LarnaLabs are intended exclusively for in-vitro laboratory research and scientific investigation. Our compounds are used by researchers in academic institutions, biotech laboratories, and independent research facilities for studies involving cellular biology, receptor binding assays, enzyme kinetics, metabolic research, neuroscience, immunology, and other controlled experimental applications.
Our products are not approved for human or veterinary use and are not intended as drugs, supplements, food products, or cosmetics. By purchasing from LarnaLabs, customers confirm that all products will be used solely for legitimate scientific research purposes.
Every compound in our catalog is verified to a minimum purity of 97% or greater as determined by reversed-phase High-Performance Liquid Chromatography (RP-HPLC) analysis. Many of our products routinely achieve purity levels of 98-99%. The exact purity value for each production batch is documented on the Certificate of Analysis that accompanies your order.
We do not release any compound that falls below our 97% purity threshold — batches that fail quality control are rejected and resynthesized. We also perform mass spectrometry identity confirmation on every batch to verify the molecular weight matches the expected theoretical value.
Most lyophilized peptides should be stored at -20°C or below in a dry, dark environment immediately upon receipt. Unopened vials stored under these conditions will maintain their specified purity and integrity through the expiration date indicated on the Certificate of Analysis.
Important storage notes:
Specific storage recommendations for each product are printed on the product label and Certificate of Analysis.
The appropriate reconstitution solvent depends on the physicochemical properties of the peptide sequence. General guidelines:
Specific reconstitution guidance is provided in the product documentation. If you have questions about a specific compound, our scientific support team is available to assist.
Yes, LarnaLabs offers custom peptide synthesis services for researchers requiring compounds not currently in our standard catalog. Custom orders can accommodate specific sequences, modifications (acetylation, amidation, PEGylation, fluorescent labeling, isotopic labeling, and more), purity levels, and quantities tailored to your experimental requirements.
To request a custom synthesis quote, contact our team with your target sequence, desired modifications, quantity, and target purity. We will provide a quotation and estimated turnaround time. Custom synthesis orders typically require 2 to 4 weeks depending on sequence complexity and length.
The expiration date for each batch is printed on the product label and Certificate of Analysis. In general, lyophilized peptides stored at -20°C under dry, dark conditions maintain their specified purity for 2 years or more from the date of manufacture. Once reconstituted, stability varies significantly by compound — consult the product documentation for specific guidance, and always aliquot to avoid repeated freeze-thaw cycles.
Yes, we offer competitive pricing for bulk and wholesale orders. Researchers and institutions requiring larger quantities or recurring supply arrangements can contact our team to discuss volume-based pricing, custom packaging, and dedicated account management. Bulk pricing is available for both individual products and multi-product orders. Please visit our contact page to discuss your specific requirements and receive a customized quote.

We also accept payments via cryptocurrency for customers who prefer decentralized payment options. All transactions are processed through secure, encrypted payment gateways that comply with PCI-DSS security standards to protect your financial information.
Yes. We prioritize customer privacy at every step. Your credit card or payment statement will display a generic merchant descriptor that does not reference peptides, research compounds, or laboratory materials. All orders ship in plain, unmarked packaging with no external branding or product descriptions visible on the outside of the box. We do not share customer information with third parties, and your purchase history is treated as strictly confidential.
There is no minimum order requirement at LarnaLabs. You can purchase a single vial of any catalog product with free worldwide shipping included. Our product pages list available size options for each compound. Custom quantities may be available upon request for specific products — contact our team for details.
Order modifications and cancellations can be accommodated if requested before the order enters processing (typically within 2 hours of placement on business days). Once an order has been picked and packaged, we are unable to make changes. To request a modification or cancellation, contact our support team as quickly as possible with your order number. We will do our best to accommodate your request based on processing status.
Yes, we can accommodate institutional purchase orders for qualified research institutions, universities, and established biotech organizations. Please contact our sales team to establish a purchase order account. We will require institutional contact information, billing details, and a signed terms agreement. Net-30 payment terms may be available for approved accounts.

Actual delivery times may vary due to customs processing, local holidays, or carrier-specific factors. You will receive a tracking number via email once your order has been dispatched.
Once your order has been dispatched, you will receive a shipping confirmation email containing your unique tracking number and a direct link to the carrier’s tracking portal. You can also view order status and tracking information through your account dashboard. Tracking updates typically begin within 12 to 24 hours of dispatch as the carrier scans the package into their network.
If your tracking information shows no movement for more than 48 hours (domestic) or 5 business days (international), please contact our support team and we will investigate the shipment status on your behalf.
All shipments use temperature-controlled packaging designed to maintain compound integrity throughout transit. Our standard protocol includes insulated shipping containers with reflective thermal barriers, pre-conditioned gel ice packs, individually cushioned compound vials in secondary containment, and temperature indicator strips. For shipments to warm climates or particularly temperature-sensitive compounds, enhanced packaging with dry ice is provided automatically at no additional charge.
Every LarnaLabs shipment is fully insured against loss, theft, and damage in transit. If your package is lost, damaged, or fails to arrive within the expected delivery window, contact our support team with your order number. We will reship your order or issue a full refund — your preference. Replacement orders are typically dispatched within 24 hours of your report without waiting for carrier investigation outcomes.
While we ship to over 100 countries, certain destinations may have import restrictions on specific research compounds, or reliable carrier service may be unavailable. If you are unsure about shipping to your location, contact our support team before placing an order and we will confirm whether we can fulfill your request and advise on any special requirements or restrictions that may apply.
Yes, a batch-specific Certificate of Analysis (CoA) is included with every order at no additional cost. Each CoA documents the product identity, batch number, HPLC purity result, mass spectrometry confirmation, physical description, storage recommendations, net weight, and manufacturing date. CoAs are generated by qualified analytical personnel and reviewed by quality assurance staff before release.
Historical CoAs for previously purchased batches are available upon request through our support team. All analytical data supporting CoA results is archived for a minimum of five years.
Yes. In addition to our internal quality control program — which includes HPLC purity analysis and mass spectrometry identity confirmation for every batch — we periodically submit products to independent third-party analytical laboratories for verification testing. These external labs operate independently from our manufacturing partners and provide unbiased confirmation of our analytical results. Third-party testing reports are available upon request for applicable batches.
Every compound is assigned a unique batch/lot number providing full traceability from raw material sourcing through synthesis, purification, quality testing, packaging, and delivery. This system allows us to retrieve complete manufacturing and analytical records for any lot, trace distribution history, and — in the very unlikely event of a quality concern — initiate targeted communications to affected customers. Batch numbers are printed on every product label and documented on the CoA.
Our multi-stage QC process covers the entire production lifecycle: raw material qualification, in-process synthesis monitoring, preparative HPLC purification, fraction analysis, lyophilization, analytical release testing (HPLC purity + mass spectrometry), documentation review, and final visual inspection. Batches must pass every stage before release. Full details are available on our Quality page.
LarnaLabs stands behind the quality of every product we ship. If a compound does not meet the specifications stated on its Certificate of Analysis, we will replace it or issue a full refund at your preference — no questions asked. Due to the nature of research compounds and the importance of maintaining chain-of-custody integrity, we cannot accept returns of opened or reconstituted products for any reason other than a quality non-conformance.
If your shipment arrives damaged or if you believe there is a quality concern, please contact our support team within 14 days of delivery with your order number and a description of the issue. We will work with you promptly to resolve the situation.
If packaging or products are visibly damaged upon delivery, document the damage with photographs before opening the outer packaging if possible. Contact our support team within 14 days of delivery with your order number and photos. We will arrange replacement shipment or a full refund based on the extent of the damage. Damaged shipment claims are handled promptly — typically resolved within 1 to 2 business days of your report.
If your order has not arrived within the expected delivery window, first check your tracking information for any carrier notifications about delivery attempts or holds. If tracking shows no useful information or the package appears lost, contact our support team. We will investigate with the carrier and, if the shipment is confirmed lost, dispatch a replacement order or issue a full refund within 24 hours of confirming the loss.
