Frequently Asked Questions
Answers to what researchers ask most. Each question also has its own page — follow a permalink to share or bookmark it.
What are these products for?
All products are sold strictly for laboratory and scientific research use only. They are laboratory reagents — not food or supplements — and are not intended for human consumption, veterinary use, or any therapeutic, diagnostic, or cosmetic purpose.
Do you provide a Certificate of Analysis (COA)?
Yes. Every production lot is registered and its COA is published on our COA page as third-party testing is finalized. Each vial carries a QR code and batch number that resolve to that lot's permanent record — scan the code, or search the batch number on the COA page.
How are your peptides tested?
Peptide lots are analyzed by an independent third-party laboratory for identity (mass spectrometry) and purity (HPLC, reported as percent by peak area). The certificate for each lot is published to its batch page as results are finalized. We report the compound identity and purity spec on every product datasheet.
Do I need an account to order?
No — checkout is open to qualified research purchasers. Optionally, you can apply for a research account; reviewed accounts receive faster order review and priority support.
How do I place an order?
Add items to your cart, enter your research and shipping details at checkout, and select “Submit order request.” Submitting a request does not charge you. We review your request for research-use eligibility, then email an itemized invoice with payment instructions. Email is monitored Monday–Friday. Orders ship within 1–2 business days after review and cleared payment. The full flow is described in our Terms of Service.
What payment methods do you accept?
Orders are invoiced by email after review. Current options include bank transfer/ACH and cryptocurrency; no payment information is collected on this website. Your order ships once payment clears. Available methods are shown at checkout and on your invoice.
What does shipping cost and how fast is it?
All orders ship via FedEx: Ground is $15 (free on orders of $300 or more), 2Day is $25, and Priority Overnight is $60. Optional Shipping Protection ($4.99) covers loss, theft, or damage in transit. Orders ship with tracking within 1–2 business days after order review and cleared payment. Full details are in our Shipping Policy.
Do you ship internationally?
No. We ship within the United States only, and we do not ship to freight forwarders for re-export. See our Shipping Policy.
How are orders packaged and stored?
Products are lyophilized (freeze-dried) peptides and a reconstitution solution, stable at ambient temperature for the duration of shipping — no cold-chain service is required. Vials are securely packaged to protect them in transit, and every parcel is carrier-tracked. Store lyophilized material at −20°C, protected from light.
Packaging is discreet. Orders ship in plain, unmarked outer boxes with no branding, product name, or indication of the contents on the outside. The sender on the shipping label reads GTR. Lot labels and documentation are inside the parcel.
What is your return policy?
Because product integrity cannot be re-verified once a package leaves our custody, chemical products are not returnable after they ship. Defective or incorrect orders are always replaced or fully refunded — file a claim within 14 days of delivery. Loss, theft, or damage in transit is covered when you add Shipping Protection at checkout; without it, risk of loss passes to the buyer at carrier handoff and we assist with the FedEx claim. Any unshipped order can be cancelled for a full refund. See our Returns & Refunds Policy.
Can I use these on myself or my animals?
No. These materials are not for human or veterinary use, and any such use is strictly prohibited. They are supplied solely for in-vitro laboratory and scientific research. Nothing on this site is medical advice, and we make no therapeutic claims of any kind.
Who is Gold Tide Research?
