About Tesamorelin Pen
Tesamorelin in a pre-filled 3 mL research cartridge — a stabilised GHRH analogue.
Tesamorelin is a synthetic analogue of growth-hormone-releasing hormone, modified for stability against enzymatic degradation. It acts upstream of growth hormone itself, prompting the pituitary to release its own GH in a pulsatile pattern rather than supplying the hormone directly.
The pen supplies the same compound as REVIVE's lyophilised Tesamorelin vials, ready in solution.
Research mechanism
The literature concentrates on:
- GHRH receptor binding at pituitary somatotrophs
- Pulsatile GH release, in contrast to exogenous GH administration
- Hepatic IGF-1 induction as the downstream readout
- Visceral adipose tissue in the published trial literature
Research applications
- GH-axis and GHRH receptor research
- IGF-1 signalling studies
- Visceral adipose tissue research
- Endocrine and pituitary-function models
- Comparative GH secretagogue work

Frequently asked questions
How is the Tesamorelin 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 Tesamorelin 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.
