Orders placed before the daily cutoff on a business day are dispatched the same day. Orders placed after the cutoff, at a weekend, or on a public holiday go out on the next business day.
Vials are packed to protect against light, moisture and impact. Compounds that require cold handling ship with a cold pack in insulated packaging. Lyophilized peptides are stable in transit at ambient temperature and should be moved to their listed storage conditions on arrival.
International destinations are handled case by case. Import rules for research chemicals vary widely and clearing customs is the buyer's responsibility. Contact us before ordering from outside the United States.
Because these are research materials whose storage conditions cannot be verified once they leave our control, opened vials cannot be accepted back. Unopened items in original packaging may be returned within 14 days of delivery for a refund less shipping.
Contact us within 48 hours of delivery with photographs of the packaging and the vial labels. We will replace or refund the affected items. Keep the packaging until the claim is resolved.
Tell us the lot number and what you observed. If independent testing shows a discrepancy against our published certificate, we refund the lot in full and pull it from sale pending investigation.
