Frequently Asked Questions
Everything you need to know before you order.
Are these products for human use?
No. All products are sold strictly for research use only — not for human or veterinary use, diagnosis, treatment, or consumption. By purchasing you confirm you are a qualified researcher handling materials in accordance with applicable laws.
Do you include a Certificate of Analysis?
Yes. Every lot is independently tested and travels with a signed COA. Each vial carries a QR code and lot number that resolve to that exact batch's COA at tomorrowpeptides.com/v/<lot> — named lab, purity %, and identity confirmation.
How are your compounds tested?
By accredited third-party laboratories (Freedom Diagnostics / Kovera / Freedom Diagnostics). Testing covers HPLC purity, net peptide content (labeled vs actual), mass-spec identity, heavy metals by ICP-MS, sterility, and endotoxin.
How fast do you ship?
Orders placed before the same-day cutoff are packed and dispatched the same business day. Peptides ship cold in an insulated mailer with a gel pack to protect the compound in transit.
What payment methods do you accept?
Crypto is our primary rail — Bitcoin and stablecoins (USDT/USDC) via a self-hosted, non-custodial checkout. No crypto yet? A guided 'pay with card' step walks you through buying crypto to complete your order. Repeat buyers can also use Zelle, Venmo, or CashApp.
Do you ship internationally?
We ship discreetly worldwide. The buyer is responsible for compliance with local import regulations for research materials.
What is your shipping protection?
Every order ships in plain, unmarked packaging with cold-chain protection. If a package is lost or arrives damaged, contact us and we'll make it right.
Can I track my order?
Yes. You'll receive a tracking link by email once your order is dispatched. Your per-lot COA is available any time by scanning the vial or visiting the verify page.
What is your return policy?
Because these are sensitive research materials, we can't accept returns of opened or temperature-exposed product. Damaged or incorrect shipments are replaced — reach out within 7 days of delivery.
How should I store the compounds?
Store lyophilized vials refrigerated at 2–8 °C and away from light. Once reconstituted, keep the working solution cold and use it fresh. Full storage notes ship on the box insert and the verify page.
