From our freezer to your bench.

Orders confirmed by 2 PM EST, Monday through Friday are picked, packed and dispatched the same business day from our US facility. Orders confirmed after the cutoff, or over a weekend or federal holiday, ship the next business day.

• Free shipping on all orders of $200 or more — otherwise a $9.95 flat rate.
• Carriers: USPS and UPS, selected for the fastest lane to your address.
• A tracking number is emailed to you as soon as your label is generated.
• Typical domestic transit time is 2–3 business days.
• Every order ships in plain, insulated outer packaging with the lot-matched COA and packing slip enclosed.

We currently ship within the United States only. International shipping is on our roadmap; if you operate a research facility abroad, contact us and we’ll let you know when your region opens.

Our peptides ship as lyophilized (freeze-dried) powder — the most stable form a peptide can take. In this state they tolerate ambient-temperature transit without measurable degradation, which is why a 2–3 day journey in standard packaging does not compromise the purity documented on your Certificate of Analysis.

On arrival, move vials into refrigeration: 2–8 °C for near-term use, or −20 °C for long-term storage, kept away from light and moisture. Storage guidance specific to each compound is printed on its product page.

If your order arrives with a cracked or broken vial, a compromised seal, or an item that doesn’t match your invoice, we make it right at no cost. Report the issue within 72 hours of delivery through our contact form, including your order number and clear photos of the affected items and packaging. Once verified, a replacement ships free of charge — typically the same or next business day.

Before disputing a charge with your bank: contact us first. Every packed order is photographed with its lot numbers and packing slip before it ships, and replacements and refunds are resolved within one business day — far faster than a card dispute, which can take weeks and delays any resolution while it is open.

Unopened, unused products in their original sealed packaging may be returned within 30 days of delivery for a refund of the product price, less original shipping costs. Contact us first for a return authorization and the return address; refunds are issued to the original payment method once the return is received and inspected.

Opened vials cannot be returned. Once a seal is broken we can no longer guarantee the integrity of the material, and reselling it would compromise the chain of custody every researcher relies on — so opened products are removed from circulation, not restocked.

The exception is quality itself. If a third-party analytical test of an opened vial disputes the purity or identity stated on its lot-matched COA, send us the report. Verified discrepancies are honored in full with a replacement or refund — your choice. We publish the proof, and we stand behind it.

Need to change a quantity, correct an address, or cancel entirely? Reach out as soon as possible — we can modify or cancel any order that hasn’t yet been dispatched. Because we ship same-day, that window can be short; once a package is with the carrier, the return policy above applies instead.
