Shipping & Returns
Last updated: June 2026
Shipping Overview
BioSource Peptides ships all orders via United States Postal Service (USPS). All products are shipped from our facility in Florida, USA. We are committed to fast, reliable delivery for qualified research customers.
Order Processing
Orders are typically processed and dispatched within 24 to 48 hours of payment confirmation, during business hours (Monday–Friday, excluding federal holidays). Orders placed after business hours or on weekends will be processed the next business day.
You will receive a shipping confirmation email with your USPS tracking number once your order has been dispatched.
Estimated Delivery Times (Domestic — United States)
Because we ship from Florida, delivery times within the continental United States are typically:
- Florida & Southeast: 1–2 business days
- East Coast & Midwest: 2–3 business days
- West Coast & Mountain States: 3–5 business days
These are estimates provided by USPS and are not guaranteed. Delays due to weather, carrier volume, or other factors beyond our control may occur.
Shipping Rates
Shipping rates are calculated at checkout based on package weight, dimensions, and your delivery location. We work to keep shipping costs as competitive as possible.
Packaging & Handling
All products are carefully packaged to preserve integrity during transit. Research peptides and compounds are shipped in appropriate laboratory-grade packaging to protect against temperature fluctuation and physical damage.
International Shipping
At this time, BioSource Peptides ships within the United States only. We do not currently fulfill international orders. This policy is subject to change — please check back for updates.
Returns & Refunds
Due to the nature of research chemical products, all sales are final. We do not accept returns under any circumstances.
In the event that a package is lost or seized in transit, we will offer a replacement order at no charge once we are able to verify the loss or seizure. Please contact us at info@biosourcepeptides.com with your order number and any supporting documentation so we can investigate promptly.
Lost or Seized Packages
BioSource Peptides stands behind every order we ship. Because all of our products are shipped domestically from Florida, USA, lost or seized packages are rare — but we take full responsibility when they do occur.
If your order does not arrive, we will replace it at no additional cost once we can verify the package was lost or seized in transit. To initiate a claim:
- Email us at info@biosourcepeptides.com with your order number and tracking information
- Allow us time to investigate with USPS on your behalf
- Once the loss or seizure is verified, a replacement order will be issued
We appreciate your patience during the verification process and are committed to making sure every research customer receives their order.
