Refund & Returns Policy
This policy explains the circumstances under which Kaizen Peptides may approve a refund, replacement, or return request for research-use-only compounds and laboratory materials.
At Kaizen Peptides, we are committed to supplying properly handled research compounds and laboratory materials.Due to the nature of these products, all sales are generally considered final.Limited refunds or replacements may be available only under the specific circumstances described below.
1. All Sales Are Final
Because Kaizen Peptides supplies research-use-only compounds and laboratory materials, we generally cannot accept returns once products have been shipped where storage conditions, handling, or product integrity can no longer be independently verified.
Returns are generally not accepted for:
- Opened or used products.
- Products that have left verifiable storage conditions.
- Customer errors when selecting or ordering products.
- Dissatisfaction based on expected product effects, outcomes, or performance.
- Products that were improperly stored, handled, altered, or compromised after delivery.
These restrictions help preserve product integrity and prevent returned laboratory materials from being placed back into inventory when their handling conditions can no longer be verified.
2. Eligible Refund or Replacement Situations
Kaizen Peptides may review a request for replacement or refund when a verified order issue falls within one of the circumstances below.
Incorrect Item Received
You received a different product from the product listed on your confirmed order.
Product Damaged During Shipping
The product arrived broken, cracked, leaking, or otherwise physically damaged during shipment.
Missing Items
One or more products shown on your confirmed order were not included in the delivered package.
Lost or Undelivered Packages
Claims involving lost or undelivered shipments may be reviewed on a case-by-case basis when available tracking information or the shipping carrier indicates that the package has been lost and cannot be successfully delivered.
To qualify for review, refund or replacement claims should generally be submitted within 7 days of delivery or within 7 days of the expected delivery issue becoming reasonably apparent.
3. Non-Refundable Situations
Refunds or replacements will generally not be issued in the following situations:
- Packages confirmed as delivered by the shipping carrier.

5. Shipping Costs
- Original shipping charges are generally non-refundable.
- If a replacement is approved because of a verified fulfillment error or qualifying shipping damage, Kaizen Peptides may cover the reasonable shipping cost associated with sending the approved replacement.
- Shipping charges resulting from customer address errors, refused deliveries, or other customer-caused delivery issues may remain the customer's responsibility.
6. Product Integrity
Maintaining the integrity of research compounds requires appropriate storage and handling.Once an order has left our control, Kaizen Peptides cannot independently verify every environmental condition during transportation or after delivery.
For this reason, opened, used, altered, compromised, or improperly stored products generally cannot be returned when product integrity or handling conditions can no longer be verified.
Customers are responsible for promptly receiving shipments, inspecting packages, and storing products according to the applicable product information after delivery.
7. Delivered but Not Received
Packages marked as delivered by the shipping carrier are generally considered delivered unless subsequent carrier information establishes that the delivery record was incorrect.
Before submitting a claim, customers should check with household members, building management, reception areas, mailrooms, parcel lockers, secure delivery locations, nearby delivery areas, and the applicable carrier.
Kaizen Peptides is generally not responsible for packages lost, removed, or stolen after confirmed delivery.
8. Incorrect Shipping Information
Customers are responsible for providing complete and accurate shipping information during checkout.
Refunds or replacements may not be available when an order is delayed, returned, lost, or misdelivered because an incorrect, incomplete, outdated, or otherwise undeliverable address was supplied by the customer.
Address corrections should be requested as soon as possible by emailing: support@kaizenpeptide.com .
Address changes cannot be guaranteed once an order has entered fulfillment or shipment.
9. Research-Use-Only Products
Products offered by Kaizen Peptides are supplied strictly for qualified scientific research, analytical testing, laboratory analysis, and in-vitro applications.
For Research Use Only.Products are not intended for human or animal consumption or use, therapeutic use, clinical use, diagnostic use, cosmetic use, food use, household use, or any other unauthorized consumer application.
Refund or replacement requests based on unauthorized use, expected biological results, or other uses outside the stated research purpose are not eligible for consideration under this policy.
10. Refund Processing
If a refund is approved, it may be issued through the original payment method or another appropriate method depending on the payment method used and available processing options.
Processing times after approval may vary depending on the applicable financial institution, payment processor, or payment method.
11. Replacement Approval
If a replacement is approved, Kaizen Peptides may ship the same product or another agreed replacement where appropriate and subject to product availability.
Approval of one claim does not establish an automatic right to future refunds, replacements, credits, or reshipments.Each request may be reviewed independently based on the circumstances and supporting information provided.

Kaizen Peptides may modify, update, or replace this Refund & Returns Policy when necessary to reflect changes in operations, shipping procedures, product-handling requirements, payment processes, or website policies.
