About Retatrutide Pen

Retatrutide in a pre-filled 3 mL research cartridge — the triple agonist at the GLP-1, GIP and glucagon receptors.

Retatrutide is a synthetic peptide that acts as an agonist at three receptors simultaneously — GLP-1, GIP and glucagon — which distinguishes it from the dual and single agonists that preceded it. The glucagon arm is the element most often isolated in the literature, since it introduces an energy-expenditure component alongside the appetite and insulin-secretion pathways of the other two.

This is the same compound supplied in REVIVE's lyophilised vials, presented instead in a pre-filled cartridge already in solution.

Frequently asked questions

How is the Retatrutide Pen supplied?

As a pre-filled 3 mL cartridge containing 300 units, holding 20 mg in 3 mL (6.67 mg/mL). It arrives in solution, so no reconstitution step is required. Store at 2–8°C and protect from light. A lot-specific Certificate of Analysis is available on request ahead of dispatch.

How does the pen differ from the vial?

The compound is the same. The vial is supplied as a lyophilised powder for reconstitution and stored at −20°C; the pen arrives already in solution in a sealed cartridge and is stored refrigerated at 2–8°C. The pen removes the reconstitution step, which is the practical difference most research operators are weighing.

REVIVE LAB is a UK limited company and all REVIVE compounds are manufactured in the United Kingdom, then shipped to the Dubai facility from which UAE orders are dispatched domestically. Each pen carries a batch number and an RVL verification code checkable at revivelab.ae/verify.
