Shipping & Returns

Order Processing

• Orders are processed and shipped within 1 business day of payment confirmation.
• Orders placed on weekends or holidays will be processed the next business day.
• You will receive a shipping confirmation email with tracking information once your order ships.

Shipping Methods & Delivery

• Choose your speed at checkout — every order ships in an insulated mailer with an ice pack regardless of tier.
• Free Ground shipping on orders $250+ (after any discount). Free shipping applies to the Ground tier; 2-Day and Overnight are always at their listed rate.
• Where UPS doesn't serve the selected speed to your address, we ship the equivalent USPS service (Priority / Priority Express) at the same rate.
• All orders ship from within the United States.
• We ship to US and Canadian addresses.
• Shipping times are estimates and not guaranteed.

Shipping to Canada

• Flat $50 international shipping on all Canadian orders, regardless of order size. The free-shipping threshold and promotional shipping offers do not apply to international orders.
• Canadian orders can be paid by card or crypto.
• Customs, duties, and import risk are entirely the customer's responsibility. Cross-border shipments may be delayed, inspected, held, or seized by customs or border authorities. We have no control over, and assume no responsibility for, customs processing in any form.
• No refunds or replacements for customs-related loss. By placing a Canadian order you expressly acknowledge and agree — via a required checkbox at checkout — that no refund, replacement, or credit will be issued for any order that is delayed, held, or seized by customs or otherwise fails to clear the border, and you waive any right to a refund or chargeback on that basis. Ordering across the border is entirely at your own risk.
• Any duties, taxes, or brokerage fees assessed by Canadian authorities are the customer's sole responsibility.

Packaging & Cold Chain

• All orders are shipped in plain, protective packaging appropriate for laboratory materials, with carrier tracking.
• Orders ship in an insulated thermal mailer built for short-transit temperature protection. The reflective interior insulation moderates package temperature through the 2-day transit window nationwide.
• Lyophilized peptides are stable for short periods at room temperature, and our packaging plus 2-day service are selected so vials arrive in good condition under typical transit conditions. Once received, vials should be stored at 2–8 °C until reconstitution.

Tracking Your Order

• Tracking numbers are provided via email once your order ships.
• Track your package on the carrier's site (UPS or USPS) using the tracking number provided.
• If you have not received tracking within 2 business days, please contact us.

Returns & Refunds

We want every order to land right. The policy below is straightforward — email support@syngyn.co or call (831) 218-5147 the moment something is off and we'll work it out.

• Damaged, defective, or incorrect items: Contact us within 7 days of delivery with photos. We replace at no charge or issue a full refund — your call.
• Unopened products, change of mind: Return within 30 days of delivery for a full refund of the product price. You cover return shipping. Original outbound shipping is non-refundable. Items must be unopened with tamper-evident seals intact.
• Missing packages: Contact us within 72 hours if tracking shows delivered but you haven't received the package. We file the carrier claim and replace once confirmed lost.
• Opened products: Cannot be returned for resale due to research-product integrity standards, but if there's a quality concern (purity, sterility, mislabeling), reach out and we'll make it right.

Refund Processing

• Approved refunds are issued to your original payment method within 3–5 business days of approval.
• Card payments are refunded through our card processor; the credit usually posts to your statement within 5–10 business days after that, depending on your bank.
• Crypto payments are refunded in the original cryptocurrency at the prevailing exchange rate at refund time. Crypto network fees and processor fees are non-refundable.
• If you don't see your refund within the windows above, email us with your order number and we'll look it up directly.

Why we'd rather work it out than have you dispute

If something goes wrong with your order — anything at all — please email or call us first. Refunds processed directly are faster (a few days vs. a few weeks for a chargeback), don't involve your bank, and don't put us in a bad spot with our payment processor. We'd rather refund you in 24 hours than fight a dispute for 60 days. Reach out and we'll handle it.
