Policy
How orders are processed, packed, and delivered.
Last updated: July 23, 2026
Peak Peptide Lab ships to addresses within the United States. We do not ship internationally at this time.
All products are sold for laboratory research use only. By placing an order you confirm the materials will be handled by qualified personnel in an appropriate research setting.
Orders are packed and shipped once payment has cleared. Orders placed before 1:00 PM PST, Monday through Friday, generally ship the same business day. Orders placed after the cut-off, on weekends, or on US holidays ship the next business day.
Because orders are paid in cryptocurrency, the clock starts when your payment is confirmed on-chain. During periods of high volume, processing may take an additional business day.
Domestic orders ship via USPS. Standard service is typically delivered within 2–5 business days after dispatch. Expedited and overnight options, where offered, are shown at checkout.
Every compound is packed to preserve stability in transit. Lyophilized (freeze-dried) research peptides are stable at room temperature for the short duration of shipping and do not require cold-chain handling in transit; store them per the guidance on each product page once received.
A flat shipping rate is shown at checkout before you confirm your order. Orders above the free-shipping threshold displayed at checkout ship at no additional cost. There are no hidden handling fees or added sales tax.
When your order ships you’ll receive a confirmation email with a tracking number at the address you provided at checkout. Please use a real, monitored email address — it is how we reach you about your order. Tracking can take up to 24 hours to show movement after the label is created.
If tracking shows your order delivered but you can’t locate it, check with others at your address and your local carrier first — most packages surface within a day or two.
If a shipment is lost in transit, or arrives damaged, contact us through the contact form with your order number and, for damage, clear photos of the packaging and vials. We’ll work with you to resolve it, including a replacement or refund where appropriate. See our Returns & Refunds policy for details.
