Shipping, handling and storage on arrival

Where we ship

To addresses in the United States only. We don’t ship internationally or to freight forwarders.

Cost

$9.95 per order, free on orders of $150.00 or more after discounts. The cost is shown in your bag before you pay.

When it leaves

Orders paid by 1pm ET on a business day usually ship the same day; later orders ship the next business day. You get an email with tracking when it leaves. Most orders arrive in 2 to 5 business days by USPS or UPS.

How it travels

Peptides ship lyophilized (freeze-dried), sealed, in plain packaging with a cold pack from May to September. Lyophilized peptides tolerate a few days at room temperature in transit.

When it arrives

1. Check the seal is intact and the lot number on the label matches the certificate (look it up on the certificates page).
2. Store sealed vials cold and dark the same day: −20 °C for long-term storage, 2–8 °C for a few weeks.
3. If anything is damaged, missing or wrong, email us within 7 days with your order number and a photo, and we’ll replace or refund it.

Returns

Unopened, sealed items can be returned within 30 days. See the return policy.
