Every order packed for integrity.

Lyophilized (freeze-dried) peptides are stable at ambient temperatures for short transit periods. However, we take extra precautions to protect compound quality during shipping.

Policies

Order processing & delivery policies.

Processing Time

Orders placed before 12:00 PM EST on business days are typically processed and dispatched within 48 hours. Orders placed after 12:00 PM or on weekends and holidays will begin processing on the next business day.

You will receive a shipping confirmation email with your tracking number once your order has been dispatched.

Order Tracking

A tracking number is emailed to you at the time of dispatch. Use the tracking number on the carrier’s website to monitor your shipment in real time.

If you have not received a tracking number within 3 business days of placing your order, contact us at support@fractionresearch.com.

Damaged or Lost Packages

If your order arrives damaged or is confirmed lost by the carrier, contact us within 5 business days of the expected delivery date. Include your order number and photos of any damaged packaging.

We will work with you to resolve the issue. Claims submitted outside the 5-day window may not be eligible for replacement.

Shipping Restrictions

We ship to all 50 US states. We do not currently offer international shipping. P.O. Box delivery is available for USPS Priority Mail only — UPS and FedEx shipments require a physical address.

It is the purchaser’s responsibility to verify the legal status of any compound in their state or jurisdiction before ordering.

Address Accuracy

Please double-check your shipping address before completing checkout. Fraction Research is not responsible for orders shipped to an incorrectly entered address.

If you notice an address error after placing your order, contact us immediately at support@fractionresearch.com. We will attempt to correct it before dispatch, but cannot guarantee changes once an order has shipped.

Extreme Weather Holds

During periods of extreme heat or weather events that could compromise cold-chain integrity, we may hold orders until conditions are suitable for safe transit. You will be notified by email if your order is placed on a weather hold.

No additional charge is applied for weather holds. Orders held due to weather can be cancelled for a full refund upon request.
