Research peptides are short chains of amino acids studied for laboratory and scientific research purposes only. Peptalix Labs supplies GMP-sourced compounds across cognitive, healing, metabolic, growth hormone, energy, skin and vitality research categories. They are not intended for human or veterinary use.

Our products are intended for qualified researchers, laboratories and institutions conducting legitimate in-vitro research. Products are sold strictly for research use and not for personal consumption, athletic use, or therapeutic treatment.

Every batch we sell — retail or wholesale — carries a published, independently verified Certificate of Analysis. Our dual USA and China operations let us offer competitive pricing without compromising on lab verification, with same-day dispatch from our USA facility.

Yes, research peptides can be legally purchased in the USA and most destinations we ship to by qualified researchers for in-vitro laboratory studies. Customers are responsible for ensuring compliance with the laws and import regulations of their own jurisdiction. Products are not FDA-approved for human or veterinary use.

Peptalix Labs operates manufacturing and quality-control partnerships in both the USA and China. Production typically takes place through our China-based partners, with quality checks, order fulfillment and dispatch handled from our USA facility.

Yes. Every batch is independently tested before it's listed for sale, using HPLC-UV analysis, frequently coupled with mass spectrometry, to confirm both identity and purity.

Yes. Every product page includes a link to view or download the exact Certificate of Analysis for that batch. You can also browse our full COA library.

Testing is performed by independent third-party laboratories, including Freedom Diagnostics and ILS Laboratories (ISO/IEC 17025 accredited). We do not test products in-house, to keep verification independent.

A typical COA confirms compound identity (via LC-MS or HPLC-RTM), purity percentage, net peptide content, lot number, and an accession or report number for traceability. Select products also include heavy metals, sterility and fentanyl screening results.

Contact our support team with your order details and the lot number from your product. We take COA accuracy seriously and will review any reported discrepancy.

Reconstitution is the process of adding a sterile liquid, typically bacteriostatic water, to lyophilised peptide powder to create a solution for research use. The general process is described on each product page.

We describe the general reconstitution process (sterile water, slow injection down the vial wall, gentle swirling) but do not provide dosing advice or individualized protocols, as our products are sold strictly for research use.

Most lyophilised peptides should be stored at -20°C prior to reconstitution. Once reconstituted, store at 2-8°C and use within 28 days. Avoid repeated temperature cycling. Specific storage notes are listed on each product page.

Orders are packaged to protect product integrity during transit. Lyophilised peptides are generally stable at ambient transit temperatures for standard shipping durations; proper storage becomes important once the order is received.

Orders placed before our daily cut-off ship same business day from our USA facility, Monday to Friday. International orders typically arrive within 5-12 business days depending on destination and customs processing.

Yes. Alongside same-day USA dispatch, we ship to Canada, Australia, the United Kingdom and most of Europe, with tracked delivery on every order.

Once an order enters processing, changes may not be possible. If you need to request a change or cancellation, contact support as soon as possible — we'll review the request, though it cannot be guaranteed once dispatch has started.

If tracking shows an unusual delay, contact support with your order number so we can review the shipment status with the carrier. For packages marked delivered but not received, please also check with neighbors and your local delivery point before reaching out.

A tracking number is provided by email once your order ships. If you haven't received tracking information within one business day of ordering, contact our support team.

Yes. Peptalix Labs offers wholesale and bulk pricing on research peptides through our China-based production partners, with quality checks and dispatch handled from our USA facility. Visit our Wholesale page for details.

Yes. Every wholesale batch carries the same independently verified Certificate of Analysis as our retail products — there is no lower tier of testing for volume orders.

Submit a request through our Wholesale page or contact our team directly. Availability, minimums and pricing tiers are confirmed per inquiry.

Accepted payment methods are displayed at checkout and may vary over time. Please refer to the checkout page for current options.

Due to the nature of research materials and handling requirements, returns and exchanges are generally limited. If you have an issue with your order, contact support promptly with your order details so it can be reviewed.

Retail orders have no set minimum. Wholesale and bulk orders are subject to minimums confirmed per inquiry — see our Wholesale page for details.
