What we do
We list research compounds and laboratory supplies and ship them within the United States. Every product on sealedpeptides.com is sold for laboratory and research purposes only. Our products are not for human or veterinary use, not for consumption, and not intended to diagnose, treat, cure, or prevent any disease.
Each product page shows the specifications provided by the supplier, such as stated purity, molecular weight and storage guidance, and links to our research library for background on the compound.
How ordering works
You can order with an account or as a guest. Either way you confirm that you are 21 or older and that the products are for research use only.
Payment options: credit or debit card (processed securely by Square) or Zelle. You get an order number by email.
USPS Priority Mail within the US, discreet packaging. Orders ship within 1 business day when in stock, after payment is confirmed. Priority Mail is free at $149.00+, otherwise $14.99; USPS Ground Advantage is $6.99, free at $75+. UPS 2nd Day Air and UPS Next Day Air are available at checkout for an added flat rate. See the Shipping Policy.
Our policy is replacement only; we do not offer refunds. Details are in the Returns Policy.
Pricing
Volume pricing is applied automatically per product and size: 2+ units: 5% off · 3+ units: 10% off · 5+ units: 20% off. Your first order, as a guest or with a new account, gets 10% off when neither your email nor your shipping address has an earlier order. You always get whichever discount is larger on an order; the two are never combined.
