Research peptides are short chains of amino acids used in laboratory experiments to study biological processes. They are intended for research purposes only and not for human or animal consumption or clinical use.

No — our peptides are provided solely for research use and are not approved for clinical, therapeutic, or diagnostic applications.

Yes — when available, each product is supplied with a Certificate of Analysis (COA) detailing purity, composition, and quality-control results.

Typical research-grade peptides are synthesized and verified at ≥99% purity; batch-specific purity, when available, is provided on each product’s COA.

Peptides are produced by solid-phase peptide synthesis (SPPS), then purified. Final products are quality-checked by independent laboratories.

We accept major credit cards (Visa, Mastercard, Amex) and Cash App for secure and convenient research material purchases.

Orders cannot be changed or canceled after submission and all sales are final. Please verify your shipping address and order details before placing your order.

Bulk pricing may be available for select products; contact our sales/support team to discuss volume discounts.

Order Minimum: Irontide Labs requires a minimum order threshold of $40.00 to process research requests.

All orders are typically processed and handed over to the carrier within 1 to 2 business days.

No — we ship to the U.S. only; international orders are not available.

You will receive a tracking number via email once your order has been dispatched to monitor its progress through either the FedEx Tracking Portal or the USPS Tracking Tool.

Primary Carrier: We use FedEx 2Day® for all domestic orders to physical street addresses — typically arriving within 2 business days. PO Box Deliveries: Because FedEx cannot deliver to PO Boxes, those orders ship via USPS Priority Mail or USPS Ground Advantage (3–5 business days).

Email [email protected] with your order number, tracking number, and a brief description of the issue (lost, damaged, or stolen). If the item arrived damaged, include clear photos of the packaging and product.

At Irontide Labs, we maintain the highest standards of chemical purity and safety. Because our products are intended strictly for in-vitro laboratory research, we maintain a strict chain-of-custody, so all sales are final — we do not offer refunds, returns, or exchanges. In the rare event of shipping damage, contact [email protected] within 24 hours with photographic evidence.

Store peptides in a cool, dry, dark place for best stability; lyophilized peptides are commonly kept at −20°C. Always follow any product-specific storage instructions.

Solvent choice depends on the peptide’s sequence and solubility; common research solvents include sterile water, dilute acetic acid, or DMSO. Consult relevant literature and follow appropriate laboratory safety procedures when handling solvents.

Lyophilized peptides can remain stable for months to years when stored properly (commonly at −20°C in a dry environment). Reconstituted stability varies by sequence, solvent, concentration, and storage — refrigerated (2–8°C) is typically stable for days to a few weeks, while frozen (−20°C to −80°C) can extend to weeks or months. Minimize freeze–thaw cycles, aliquot when freezing, and label with the reconstitution date.

Yes — peptides can degrade over time from moisture, heat, light, oxidation, or repeated freeze–thaw cycles. Proper storage and careful handling help minimize degradation.

Products are sold for research use only. Buyers are responsible for complying with all applicable local, state, and federal laws.

A license is generally not required to purchase, but buyers must confirm the products are for research use only and not for human or animal use. Buyers are responsible for complying with all applicable local, state, and federal laws.
