About NEXA

Who we are

NEXA Medicals focuses on peptide products, with NEXA Retatrutide supplied in the pre-filled NexaPen. Our product and partner overview brings together the pen specification, laboratory results, manufacturing background and distribution channels.

The product: three receptors, one molecule

Retatrutide is a peptide developed by Eli Lilly that acts on GIP, GLP-1 and glucagon receptors. These pathways are involved in appetite, satiety and energy metabolism. The overview describes a once-weekly subcutaneous format and an approximately six-day half-life.

Retatrutide remains investigational. This overview is not medical advice or a personal dosing recommendation; any medical use requires qualified clinical guidance and compliance with local regulations.

Inside the NexaPen kit

• Pre-filled NexaPen: 40 mg of retatrutide, with an adjustable pen specification of 2.5–10 mg per injection.
• 8 disposable needles: 32G × 4 mm.
• User Guide: included in every pack.
• Authenticity verification: a verification system in every NEXA pack.

Quality & verification

The latest published laboratory report shows 99.7% purity and 40+ mg measured per pen, against the declared 40 mg. The HPLC test is dated 24 September 2026. The product overview also reports no degradation in stability tests above 30 °C; this is a test result, not a replacement for the storage instructions supplied with the product.
