Triple agonist: GLP-1 / GIP / Glucagon
Retatrutide (LY-3437943) is a synthetic peptide with agonist activity at the GLP-1, GIP and glucagon receptors. Supplied lyophilized as a reference reagent for in-vitro study of incretin and glucagon receptor signaling.
- Fill: 20 mg / vial
- Pack: 1 vial · 20 mg total
- Purity: ≥99%
For in-vitro laboratory research use only. Not for human or animal consumption, medical, diagnostic or therapeutic use.
Receptor pharmacology
Agonist activity at the GLP-1, GIP and glucagon receptors. The glucagon receptor component is what separates retatrutide from GLP-1-only and GLP-1 / GIP dual agonists in receptor-binding and signalling assays.
Delivery times
Delivery times
Standard delivery is 5 to 8 business days and counted from the day your order is dispatched rather than the day you order.
These are carrier estimates and are not guaranteed. Remote and northern destinations can take longer. You will receive a shipping confirmation email with tracking when your order is dispatched.
Returns and refunds
Returns and refunds
All sales are final once opened. Once a vial's tamper seal is broken, or a lyophilized peptide has been reconstituted, it is considered used and is no longer eligible for return, exchange or refund. This protects every customer from receiving compromised material.
Damaged shipments. Photograph the parcel before touching the contents and email us within 48 hours of delivery. We reship the affected items at no cost once we confirm the damage.
Certificate mismatch. If the Certificate of Analysis does not match the vial you received, contact us within 7 days of delivery for a full replacement.
Cancellations. Free until the order enters the packing queue, typically within 2 hours of checkout. After a tracking label is generated you may refuse delivery and return for a refund less outbound shipping and a 15% restocking fee.
Approved refunds are issued to the original payment method within 3 business days of approval. Card issuers typically post the credit within 5 to 10 additional business days. Store credit is issued the same business day.
Storage and handling
Storage and handling
Vials are packed protectively for transit. Lyophilized peptides are stable at ambient temperature for the length of a domestic shipment, so parcels are not shipped refrigerated.
On arrival, store the lyophilized vial per the specification on its label. Handling, storage and disposal are the responsibility of a qualified researcher.
