Every order ships in a heat-shield bubble mailer that buffers against temperature swings in transit, and many products are first packed in a rigid, felt-lined magnetic-closure box before going inside it — packaging varies slightly for items that don't fit the standard box. Research materials don't need to be kept cold during shipping, despite the common concern: most of what we ship is lyophilized (freeze-dried) powder, which stays stable at ambient temperature for the duration of transit, and that stability is exactly why we ship this way instead of using cold packs. Once your order arrives, the storage guidance on the product page picks up from there.

Orders placed before 7:00 AM Central Time, Monday - Friday, ship the same day, and anything placed after that cutoff, or over a weekend or holiday, ships the next business day. Orders of $100 or more qualify for free UPS Ground shipping, and flat-rate UPS Ground covers everything below that threshold with the same transit time either way. In addition, we offer a 2-Day shipping option at checkout. For more information on our shipping process, see the full shipping FAQ; for a delivery or tracking issue, please contact us directly.

Rather than testing for purity alone, PekCura Labs has every batch independently evaluated across six analytical categories: identity, purity, quantity, sterility, endotoxins, and heavy metals. Testing is performed by an ISO 17025:2017-accredited laboratory, and all materials are manufactured in the United States. Each vial lists its exact milligram amount and includes a QR code linking directly to the batch's test results and Certificate of Analysis, keeping documentation just a scan away. That transparency is what trust is built on here — not a claim, but something researchers can verify for themselves, batch by batch. And it doesn't end at checkout: our support team remains available to researchers and laboratories before and after every order.

We accept three secure ways to pay at checkout. Pay with credit or debit, with most major cards accepted and processed through a secure, encrypted system directly at checkout. Link Bank to Pay (ACH) connects directly to your checking or savings account through your mobile banking app, using bank-grade encryption to authorize payments instantly — no credit card limit to work around, and no physical paperwork involved. GreenPay offers that same direct bank-to-bank transfer using your routing and account number instead of an app login, with a checkout experience as simple as any modern digital payment.
