Order Lifecycle

FROM CHECKOUT TO DELIVERY

Every order follows a consistent, quality-controlled process from the moment you check out.

ORDER CONFIRMED

You’ll receive an email confirmation immediately after checkout. Your order enters our fulfillment queue and is assigned to the current batch.

QUALITY VERIFICATION

Your specific batch is matched against its certificate of analysis. Each vial is inspected for seal integrity, labeling accuracy, and correct dosage before it leaves our facility.

PACKAGING & DISPATCH

Products are packaged in protective, temperature-appropriate packaging and handed off to USPS. Orders placed before 3 PM CT ship the same business day.

TRACKING EMAIL SENT

Once your order is scanned by the carrier, you’ll receive an email with a tracking number and a direct link to monitor delivery progress in real time.

DELIVERED

Standard delivery typically arrives within 2–4 business days after shipping. Delivery times may vary for remote areas, Alaska, and Hawaii.

ADDITIONAL SHIPPING DETAILS

All orders are shipped in plain, unmarked packaging with no external branding or product descriptions visible. The return address shows our company name only.

Lyophilized peptides are stable at room temperature during transit. Our packaging is designed to protect against typical temperature variations during shipping. For extended storage after arrival, refrigeration is recommended.

In the rare event your order is lost or damaged in transit, contact us at support@improvedpeptides.com with your order number and we’ll investigate and make it right.

We can ship to P.O. boxes and military APO/FPO addresses via USPS. Please note that delivery to these addresses may take additional time beyond our standard estimate.

Our same-day shipping cutoff is 3 PM CT, Monday through Friday. Orders placed after this cutoff, or on weekends and holidays, ship the next business day. You’ll still receive a confirmation email immediately regardless of when you order.

International

INTERNATIONAL SHIPPING

Where we ship

We ship from the United States to select international destinations. The country selector at checkout is the definitive list: if a country does not appear there, we are not able to ship to it at this time.

Destinations currently served are Canada, the United Kingdom, Ireland, the Netherlands, Poland, the Czech Republic, Romania, Bulgaria, Hungary, Croatia, Slovakia, Slovenia, Estonia, Latvia, Lithuania, Portugal and Greece. We add destinations as we are able to support them reliably.

Rates, minimum and delivery times

International orders ship via USPS Priority Mail International, tracked from the United States. Shipping is a flat $39 to the destinations listed above, and is free on orders over $499. Rates for any destination added later are shown at checkout before you pay.

International orders have a $150 minimum.

Expected transit is 7 to 21 business days. Delivery depends on your national postal service and on customs processing, so transit times are an estimate and not a guarantee.

Customs, duties and taxes

Your order ships from the United States. Import duties, taxes and customs fees are set by your country, are the responsibility of the recipient, and are not included in your order total. We cannot calculate or collect them in advance.

Orders held or seized by customs are not refunded and are not reshipped. Please check your own country’s import rules before ordering.

International tracking

Your tracking number works throughout transit, but international tracking commonly goes quiet after the export scan leaves the United States. This is normal and does not mean your order is lost.

Updates usually resume once your national postal service receives the parcel. Some carriers post no further scans until the parcel is delivered.

Product availability

Some products are available for domestic shipping only. If your cart contains one of them, it is flagged at checkout and you will need to remove it or use a US shipping address.
