Processing Time

We aim to process and ship all orders within 1–3 business days of purchase. You will receive an email with tracking information as soon as your order ships.

Where We Ship

We currently ship within the United States only. Due to state-level restrictions on research peptide sales, we are unable to ship to Massachusetts or Connecticut. Orders placed with a shipping address in either state will not be able to complete checkout.

Packaging

Orders are packaged discreetly and securely to protect your products in transit. All items are sold strictly for research use — see our Research Use Only (RUO) Policy for full terms.
