Shipping Policy

Every order has two separate timing windows: a dispatch window (how long we take to prepare your order and hand it to the carrier) and a transit window (how long the carrier takes to deliver it). They are counted separately, one after the other, and both are counted in business days.

Each product listing shows a shipping label — either "In Stock — Ships Same Day" or "In Stock — Ships in 7 Business Days". Those labels describe the dispatch window only. They are not delivery estimates. The label on the slowest item in your order sets the dispatch timing for the whole order. For orders outside our local delivery area, transit is then up to 3 business days on top of dispatch.

The short version: place an in-stock order Monday through Friday before 3:00 PM Pacific and it is dispatched that same day. Order after 3:00 PM Pacific, on a weekend, or on a US federal holiday and it is dispatched the next business day. In every case we dispatch within 2 business days, and transit is up to 3 business days after that.

"Ships within" means processing time

"Ships within" refers to our processing and dispatch time — how long we take to prepare and hand off your order. It is not a delivery estimate and not a guarantee of carrier transit time after dispatch.

Once a package leaves our hands, delivery speed depends on the carrier. For addresses outside our local delivery area we commit to up to 3 business days in transit after dispatch. See 3-day shipping below for exactly how that window is counted, Shipping days and delivery days for which days of the week count, and When delivery can take longer than 3 business days for the circumstances that can extend it.

We ship Monday through Friday only. All dispatch windows below are counted in business days — weekends and US federal holidays are not counted. An order placed on a Saturday, a Sunday, or a US federal holiday begins its count on the next business day.

Same-day dispatch and the 3:00 PM Pacific cutoff

An item labeled "In Stock — Ships Same Day" is on our shelf and ready to go out today.

Order it Monday through Friday before 3:00 PM Pacific Time and we dispatch it the same day. The cutoff exists because our last carrier pickup of the day is at 5:00 PM Pacific; 3:00 PM is the point at which we can still reliably pick, pack, label, and hand off your order before that pickup leaves.

Order after 3:00 PM Pacific, on a Saturday or Sunday, or on a US federal holiday, and your order is dispatched on the next business day. There is no carrier pickup on those days, so nothing can leave our hands.

In every case, a same-day item is dispatched no later than 2 business days after your order date. That is the outer limit we commit to, and it holds even in the rare event that a same-day hand-off is missed.

The cutoff is measured on Pacific Time, not your local time. Our clock is what determines whether your order makes today’s pickup — 3:00 PM Pacific is 6:00 PM Eastern.

Dispatch is not delivery. Once your order is handed to the carrier, transit follows separately and takes up to 3 business days — see 3-day shipping below.

7 business day items and mixed orders

An item labeled "Ships in 7 Business Days" is prepared to order rather than held on the shelf, so it is not eligible for same-day dispatch. It is dispatched within 7 business days of the order date.

If your order contains any item labeled "Ships in 7 Business Days", the entire order is dispatched within 7 business days of the order date — orders are dispatched together, so the 3:00 PM same-day cutoff does not apply to it — unless Central Coast Peptides separately arranges a split shipment with you.

If you would prefer your in-stock items sent first, contact us and we will let you know whether a split shipment is possible for your order.

Local delivery

For Local delivery in San Luis Obispo County and the Santa Maria area ($10.50 flat rate, free on orders over $200):

Local delivery has two steps, and both are ours: we pack your order, then we bring it to you on our next local delivery run. There is no carrier involved. The delivery run is a separate day from the packing day — we do not deliver an order the same hour we pack it.

For an order containing only "Ships Same Day" items: order Monday through Friday before 3:00 PM Pacific and we pack it that same day and deliver it the next business day. Order after 3:00 PM Pacific, on a weekend, or on a US federal holiday and we pack it the next business day and deliver it the business day after that. Either way your order is delivered within 2 business days of when you placed it.

Your receipt shows both dates side by side — the day we pack your order and the day it is delivered — so there is no guessing which one is which.

If the order contains any "Ships in 7 Business Days" item, the entire local order is packed and delivered together within 7 business days of the order date, unless a split delivery is separately arranged with you. Same-day packing applies to in-stock items only.

Local delivery runs Monday through Friday only, and weekends and US federal holidays are not counted toward either step.

Ordering before 3:00 PM does not mean same-day delivery. The 3:00 PM Pacific cutoff decides the day we pack your order, not the day it arrives. We run our own route and will contact you to arrange the hand-off, so a local order placed at 1:00 PM is not promised on your doorstep that afternoon. The next business day is the earliest, and two business days is the outside limit.

3-day shipping

Shipping is a $18.99 flat rate for delivery addresses outside our local delivery area, and it is free on orders over $200. The dispatch rules above apply in exactly the same way.

All shipped orders go by UPS. Because UPS cannot deliver to them, we do not ship to PO Boxes or to APO, FPO, or DPO military addresses. Please enter a street address where UPS can deliver; checkout will not accept a PO Box or military address.

Once your order has been dispatched, transit takes up to 3 business days. This is what we commit to for every standard shipping order to the contiguous United States.

The transit window is counted separately from the dispatch window. It is not part of the same count, and the two are not interchangeable. Dispatch happens first; transit begins once the carrier has your package.

To state the total plainly: your order is dispatched first, and up to 3 business days of transit follow. An in-stock item ordered on a Monday at 1:00 PM Pacific is dispatched that same Monday and estimated to arrive by that Thursday. The same item ordered on Monday at 4:00 PM Pacific — after the cutoff — is dispatched Tuesday and estimated to arrive by that Friday. A 7-business-day item ordered on a Monday is dispatched by the following Wednesday and estimated to arrive by the Monday after that.

Your order confirmation email and your on-screen receipt both show two specific calendar dates for your order — the date we dispatch by, and the estimated delivery date. Those dates are calculated with the same business-day rules described on this page.

Cutoff table: when your order goes out

This table covers in-stock items only. Any order containing a 7-business-day item follows the 7-business-day rule instead.

The clock starts when your order is placed. For orders paid by card, Venmo, or any other method we accept, the dispatch window is counted from your order timestamp, not from when the payment settles.

Your order confirmation email and on-screen receipt show the exact dates that apply to your order, calculated with these rules and the current US federal holiday calendar.

Shipping days and delivery days

We dispatch Monday through Friday only. We do not dispatch orders on Saturdays, Sundays, or US federal holidays. Our last carrier hand-off of the day is at 5:00 PM Pacific, which is what the 3:00 PM order cutoff is built around.

Carriers deliver Monday through Saturday. There are no Sunday deliveries. UPS states this directly: it offers Monday through Saturday services for residential and commercial packages, and there are no pickups nor deliveries on Sunday (ups.com).

For that reason, every window on this page is counted in business days. Saturdays, Sundays, and US federal holidays do not count as dispatch days and do not count as transit days.

Counting from the day your order is dispatched, the 3 business day transit window works out as follows:

A US federal holiday falling inside the window pushes each of these estimates one business day later.

Every shipped order goes by UPS. We do not use USPS or any other carrier for shipped orders.

When delivery can take longer than 3 business days

The 3 business day transit window is our standard estimate for the contiguous United States. It is an estimate, not a guaranteed delivery date. The following circumstances can extend it, and they are outside our control:

If your estimated delivery date has passed, or your tracking has not updated for more than 3 business days, contact us at Support@centralcoastpeptides.com and we will open a trace with the carrier on your behalf.

Addresses and delays

Please double-check your delivery address before submitting. We ship by UPS only, so we cannot deliver to PO Boxes or APO, FPO, or DPO military addresses. We are not responsible for delays or non-delivery caused by an incorrect or incomplete address.

FAQ
Are your peptides third-party tested for purity, and where is the testing performed?

Yes. Every product offered by Central Coast Peptides is independently analyzed prior to release by a California-based ISO/IEC 17025-accredited analytical chemistry laboratory — an independent contract testing facility that operates outside our supply chain and reports directly to us on each lot.

Testing is conducted using industry-standard analytical methods, including:

  • High-Performance Liquid Chromatography (HPLC) — quantifies the target compound and identifies impurities by separation.
  • Liquid Chromatography–Mass Spectrometry (LC-MS) — confirms molecular identity and molecular weight against the reference standard.
  • Residual solvent, moisture, and endotoxin screening where applicable to the compound class.

Lots that fail to meet our internal identity and purity specifications are rejected and are not offered on this site. Lot-specific results are documented on the Certificate of Analysis (COA) for that lot.

A Certificate of Analysis (COA) is available to verified researchers upon written request at Support@centralcoastpeptides.com. All products are supplied strictly for in-vitro laboratory research and are not intended for human or animal consumption, diagnostic use, therapeutic use, or any clinical application.

What’s it like ordering from Central Coast Peptides?

Browse the catalog, pick your vial or kit, and check out. Orders are confirmed within minutes. In-stock items ordered Monday–Friday before 3:00 PM Pacific are dispatched the same day; items badged “Ships in 7 Business Days” go out within 7. Then up to 3 business days in transit. Questions? A person on California’s Central Coast replies to Support@centralcoastpeptides.com within one business day, usually sooner.

How fast is shipping and support?

Items badged “Ships Same Day” are dispatched the same day when you order Monday–Friday before 3:00 PM Pacific; after 3:00 PM Pacific, on a weekend, or on a US federal holiday they go out the next business day, and never later than 2 business days. Items badged “Ships in 7 Business Days” are dispatched within 7. That is our handling time, not the delivery date. Carrier transit is counted separately after dispatch and takes up to 3 business days. We dispatch Monday–Friday only, carriers deliver Monday–Saturday and never on Sunday, and weekends and US federal holidays are not counted in either window.

Email replies within one business day, phone answered during business hours — both go to our team on California’s Central Coast, not an offshore queue.

How fast is local delivery?

Local delivery is a $10.50 flat rate (free on orders over $200) covering San Luis Obispo County and the Santa Maria area. It has two steps, and both are ours: we pack your order, then we bring it to you on our next local delivery run — a separate day, with no carrier involved.

If your order contains only Ships Same Day items, ordering Monday–Friday before 3:00 PM Pacific means we pack it that day and deliver it the next business day. After 3:00 PM Pacific, on a weekend, or on a US federal holiday we pack it the next business day and deliver it the day after that. Either way it arrives within 2 business days of when you placed it.

To be clear: ordering before 3:00 PM does not mean same-day delivery. The cutoff sets the day we pack your order, not the day it arrives. Your receipt shows both dates side by side.

If your order contains any Ships in 7 Business Days item, the entire local order is packed and delivered together within 7 business days, unless we separately arrange a split delivery with you. Local delivery runs Monday–Friday only, and weekends and US federal holidays are not counted.

My order has both same-day and 7 business day items. When does it ship?

An item labeled Ships Same Day on its own is dispatched the same day when ordered Monday–Friday before 3:00 PM Pacific. But if your order contains any item labeled Ships in 7 Business Days, the entire order is dispatched together within 7 business days of the order date — the same-day cutoff does not apply to it — unless we separately arrange a split shipment with you.

“Ships within” is our processing and dispatch time — it is not the delivery date. Carrier transit follows dispatch and takes up to 3 business days, counted separately. We dispatch Monday–Friday only, carriers do not deliver on Sundays, and weekends and US federal holidays are not counted in either window. Full details are in the Shipping Policy.

Can I return an order or get a refund?

No. All sales are final. We do not accept returns, exchanges, or refunds — including for a change of mind, an ordering mistake, or an unused product — except where required by applicable law. If you received the wrong item or an item damaged in transit, contact us within 30 days of delivery and we will make it right. See our Return & Refund Policy and Terms of Sale.
