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.
Research mechanism
Research interest centres on:
- GLP-1 receptor agonism — insulin secretion and gastric emptying pathways
- GIP receptor agonism — incretin signalling studied alongside the GLP-1 arm
- Glucagon receptor agonism — hepatic glucose output and energy expenditure
- Combined triple-receptor pharmacology in metabolic study models
Research applications
- Incretin receptor signalling research
- Body-composition study models
- Glucose and lipid metabolism research
- Comparative agonist pharmacology
- Hepatic steatosis research models

Frequently asked questions
How is the Retatrutide Pen supplied?
As a pre-filled 3 mL cartridge containing 300 units, holding 10 mg in 3 mL (3.33 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.
Where is the Retatrutide Pen manufactured?
REVIVE LAB is a UK limited company and all REVIVE compounds are manufactured in the United Kingdom, then shipped to the London facility from which UK orders are dispatched domestically. Each pen carries a batch number and an RVL verification code checkable at revivelab.uk/verify.
Do you deliver research pens across the UK?
Yes — 24 hour delivery to mainland UK, with orders placed before 4 PM dispatched the same day. Pens ship in insulated cold-chain packaging with a temperature indicator. £8 standard delivery, free over £100. Crypto (USDT) or Whop.
