FAQ

What are research peptides used for?

All products sold by Nextday Sciences LLC through Nextday Peptides are intended for scientific, analytical, and in-vitro laboratory research purposes only. They are commonly used in controlled research environments for studying biochemical pathways, molecular interactions, and compound characterization. Products are not intended for human or veterinary use and are not for medical, therapeutic, or diagnostic applications.

Do you provide Certificates of Analysis (COAs)?

Yes. COAs are provided for box (10-vial) products when available and are searchable in our COA Library. Single-vial COAs may be available by request depending on partner documentation availability. COAs are for informational and research-reference purposes only.

How can I find a COA for my product?

You can search our COA Library using the product name, SKU, or batch/lot number. If a COA is not listed, contact support at orders@nextdaypeptides.com to inquire about availability.

What is the difference between single vials and boxes?

Single vials are individual units, while boxes contain 10 vials of the same product. COA documentation availability and fulfillment workflows may differ between singles and boxes.

How long does it take to ship my order?

Orders typically ship within 1–2 business days after payment has been received, verified, and approved. Shipping times may vary based on destination, carrier selection, inventory location, and order volume. We ship to U.S. domestic addresses only.

When will I receive tracking information?

Tracking information is usually issued once your shipping label is created and the package is transferred to the carrier. You will receive an email notification when tracking becomes available.

What payment methods do you accept?

Available payment methods are shown at checkout and may include credit/debit cards, Link Money, bank transfer, Zelle, Venmo, Cash App, and cryptocurrency. In some cases, alternate remittance instructions may be provided after checkout. Payment methods may vary by order and processor availability.

Do you accept credit cards?

Yes. Credit and debit cards may be accepted when that option is displayed at checkout (Visa, Mastercard, American Express, and Discover, subject to processor and issuer availability). If card checkout is unavailable for a given order, alternate approved payment methods will be shown or provided.

Do you offer same-day or expedited shipping?

Overnight, expedited, and same-day processing options may be available and will display at checkout if eligible. Availability depends on product eligibility, inventory location, destination, and daily cutoff times.

Is my information kept secure?

Yes. We use industry-standard practices to protect customer information. Payment card details are processed by third-party payment providers and are not stored as complete card numbers on our servers. Order and support communications are handled securely.

Can I contact support with questions about my order or documentation?

Yes. For questions about orders, payments, COAs, or fulfillment, contact orders@nextdaypeptides.com. Most concerns can be resolved directly through support.

Are these products legal to purchase?

Products are sold strictly for laboratory research use and must be handled by qualified professionals in appropriate research settings. Buyers must be at least 21 years of age and are responsible for ensuring compliance with all applicable local, state, and federal regulations. Nextday Sciences LLC is not a compounding pharmacy.
