What customers say
Research overview
Tesamorelin is a synthetic analogue of human growth-hormone-releasing hormone (GHRH), sometimes written Tesamorelin peptide, consisting of the full 44-amino-acid sequence with a trans-3-hexenoic acid group attached to the N-terminus. Supplied here as a UK-manufactured liquid peptide solution for researchers looking to buy Tesamorelin in the UK, this modification confers resistance to DPP-IV enzymatic cleavage, extending its biological activity compared to native GHRH.
DPP-IV Resistance and Stability
The defining characteristic of Tesamorelin in research contexts is its enhanced stability. Studies have examined how the N-terminal hexenoyl modification protects against DPP-IV cleavage, the resulting extended half-life compared to unmodified GHRH analogues, and the implications for sustained GHRH receptor engagement in preclinical models.
Visceral Adipose Tissue Research
Tesamorelin has been studied in the context of visceral adiposity, particularly in relation to GH-mediated lipolysis in visceral adipose depots, IGF-1 axis stimulation and downstream metabolic effects, and lipodystrophy models where GH axis dysregulation affects fat distribution.
IGF-1 Axis Research
As a GHRH analogue, Tesamorelin stimulates endogenous GH secretion with downstream effects on IGF-1 production. Research has focused on hepatic IGF-1 synthesis in response to pulsatile GH stimulation, the IGF-1 binding protein profile under Tesamorelin-mediated GH pulses, and long-term axis dynamics in preclinical models.

Frequently asked questions
Is a Certificate of Analysis included?+
Yes. Every order ships with a third-party CoA matched to the lot number printed on your cartridge. A sample CoA is available on the site.
How is purity verified?+
Each batch is HPLC-tested for purity and mass-spec confirmed for identity, then tested for heavy metals, residual solvents and endotoxins.
Does the solution need reconstituting?+
No. The cartridge is supplied as a ready-to-use liquid solution in 3ml bacteriostatic water.
How is it shipped and stored?+
Validated temperature-controlled packaging, UK next-day dispatch. Store at 2–8°C on arrival, do not freeze, 12-month shelf life.
Who is this supplied to?+
Qualified personnel for in vitro laboratory research and analytical work only. Not for human or animal consumption.
