Frequently Asked Questions
Orders & Payments
Credit and debit cards — Visa, Mastercard, American Express, and Discover — and CashApp. All payments are processed through a secure payment provider. Card details never touch our servers.
Payment is taken at checkout. Enter your card details, click Complete Order, and you'll receive an order confirmation by email once payment clears.
Check your spam or promotions folder first, since order emails sometimes land there. If it's not there after an hour, email support@coastalpeptides.com with the name and email address used at checkout and we'll confirm the order manually.
Email support@coastalpeptides.com as soon as possible. We can usually make changes before an order is packed, but once it's been handed to the carrier we can't recall or redirect it.
We can't merge orders once payment is taken. If you've placed a second order and neither has shipped, email support@coastalpeptides.com with both order numbers and we'll see what we can do.
Shipping & Delivery
We ship within the United States and to Canada.
US orders of $250 or more ship free. US orders under $250 are a flat $15. Overnight delivery is available at checkout for an additional charge — note that PO boxes and some rural addresses aren't eligible for overnight service.
Orders placed before 1pm PT on a business day ship the same day. Everything else goes out the next business day. Transit is typically two business days once the package is with the carrier, though carrier holidays can add transit time.
We ship out of our fulfillment center in California.
Tracking is emailed automatically when your order leaves. If it hasn't arrived within one business day of your confirmation, check your spam folder.
You can also look up your tracking number anytime at: https://coastalpeptides.com/ts-shipment-tracking/
Carrier scans sometimes go quiet in transit, particularly over weekends. If there's been no movement for more than three business days, contact us — and if you added Shipping Protection at checkout, see the claims section below.
Package Protection & Claims
Shipping Protection is package protection from Route, our protection partner. It covers your order if it's lost, stolen, or damaged in transit. It's added to your order automatically and appears as its own line in your order summary — you can remove it at checkout if you'd rather not have it.
File directly with Route at claims.route.com. You'll need either your Coastal Peptides order number or your Route ID, plus the email address on the order. Route reviews claims within one to two business days.
The windows are set by Route and are strict:
- Marked delivered but not received — no earlier than 5 days after the delivery date, and no later than 30 days.
- Stuck in transit — no earlier than 7 days after the last tracking update, and no later than 30 days.
- Damaged — within 30 days of delivery. Photographs of the item and the packaging are required, so keep the box.
Route will either replace the order or refund it.
Contact the carrier first with your tracking number, as most missing packages are located that way. Then email support@coastalpeptides.com and we'll help where we can. Without protection we can't guarantee a replacement for a package the carrier shows as delivered.
Testing & Certificates of Analysis
Every batch is sent to an independent US laboratory before it's made available. Current testing covers identity, purity, and quantity per vial by HPLC. We're expanding the panel through 2026 to add sterility, endotoxin, heavy metals, and pH.
Certificates of analysis are published on our Test Results page — no account or email required. Every vial also carries a QR code on the label that takes you to the results for that product.
Scan the QR code on the label, then match the lot number printed on your vial to the lot listed on the page.
The compound tested, the lot number, the testing laboratory, the date, and the results for each method run.
Yes. Independent verification is welcome and we don't restrict it.
Products & Handling
Synthetic peptide compounds supplied for in-vitro laboratory research. They are not drugs, foods, cosmetics, or medical devices, and are not intended for human or veterinary use.
As lyophilized powder in a sealed vial. The quantity is small and often appears as a thin film or a small cake at the base of the vial rather than an obvious volume of material — this is normal and expected for a freeze-dried peptide.
Sealed, cool, dry, and away from light. Storage conditions for each product are listed in the specifications on its product page.
Purity is reported per batch on the certificate of analysis for that lot rather than as a blanket figure, since it's measured for every batch individually.
No. Coastal Peptides supplies research materials only and does not provide protocols, handling guidance, or usage instructions of any kind. This applies to all products and all customers without exception.
Our full catalog is on the Shop page. Products are listed under our own SKU naming.
Accounts, Discounts & Loyalty
Yes. An account is required to complete checkout.
Discounts apply automatically based on how many vials of a product you buy — 5% at 2–3, 8% at 4–7, and 12% at 8 or more. The tier is shown on each product page and applies at checkout without a code.
Codes are case-sensitive and some are limited to one use per customer, to specific products, or to a minimum order value. If it still won't apply, email support@coastalpeptides.com with the code and what you're seeing.
Yes. Discount codes apply on top of the bulk tier price.
Lab credits accumulate on qualifying purchases and can be redeemed for a discount on a future order. Your balance appears at checkout when you're signed in.
Research Use & Compliance
It means these materials are sold solely for in-vitro laboratory research. They are not for human or veterinary use, not for diagnostic or therapeutic application, and have not been evaluated by the FDA. Purchasers confirm this at checkout.
urchasers must be at least 21 years of age and buying for in-vitro research purposes only.
No. Because of the nature of these materials, we can't accept returns or resell anything that has left our facility, so all sales are final once an order ships.
