FAQ

What are research peptides used for?

All products sold on this site 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 stability. Products are not intended for human or veterinary use.

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.

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, you may contact support 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 is received and verified. Shipping times may vary based on destination, carrier selection, and order volume.

When will I receive tracking information?

Tracking information is usually issued once your shipping label is created and scanned by the carrier. You will receive an email notification as soon as tracking becomes available.

What payment methods do you accept?

Currently accepted payment methods include Zelle, Venmo, Cash App, and select cryptocurrencies. After checkout, you will receive step-by-step payment instructions both on the receipt page and via email.

Why don’t you accept credit cards?

Research peptides are classified as a high-risk payment category. Credit card processors require extensive compliance and underwriting. We are actively working through these requirements and plan to offer card payments in the future.

Do you offer same-day or expedited shipping?

Expedited and same-day delivery options may be available in select regions and will display at checkout if eligible. Availability depends on inventory location and cutoff times.

Is my information kept secure?

Yes. We take data security seriously and use industry-standard practices to protect customer information. Payment instructions and order communications are handled securely and privately.

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

Absolutely. If you have questions about orders, COAs, or fulfillment, you can reach our support team at orders@nextdaypeptides.com.

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 are responsible for ensuring compliance with all local, state, and federal regulations.
