Tesamorelin 20mg Pen

Tesamorelin (TH9507) is a synthetic analog of growth hormone-releasing hormone (GHRH). It is a stabilized version of the natural 44 amino acid releasing factor (GRF 1-44), with a trans-3-hexenoic acid group added to the N-terminus that protects it from being broken down too quickly in the body. That added stability is what separates it from earlier GHRH peptides like sermorelin. Instead of replacing growth hormone the way injectable HGH does, tesamorelin works one step upstream: it binds the GHRH receptor on the pituitary and tells the gland to make and release its own growth hormone in natural pulses. In the published research, tesamorelin is best known for its effect on visceral adipose tissue, the deep abdominal fat that sits around the organs, and this is the body of work that made it one of the most-studied GHRH analogs. People use it for body composition, recovery, sleep, and as part of GH-optimization and longevity stacks.

The ProPeptide 20mg pen is a pre-filled FlexiPen device: 20mg of tesamorelin in a 3mL cartridge, ready to use out of the box. No reconstitution, no bacteriostatic water, no syringes to draw. You uncap, dial, and click-dose subcutaneously, with the leaflet specifying a minimum single injection of 2mg (30 clicks). The box includes 10 pen needles.

Works with your own GH system.

Tesamorelin is a releasing hormone, not a replacement. It prompts the pituitary to release growth hormone in natural pulses rather than introducing exogenous HGH, so the feedback that regulates GH stays intact. This is the reason it sits in a different category from synthetic HGH.

Tesamorelin is a GHRH analog, which means it acts at the top of the growth hormone axis rather than replacing the hormone itself. The published mechanism work spans cell, animal, and human clinical research. Three things come up repeatedly:

GHRH receptor agonism

Tesamorelin binds the GHRH receptor on the somatotroph cells of the pituitary gland: the same receptor the body's own growth hormone-releasing hormone uses. This signals the pituitary to synthesise and secrete growth hormone. Because it acts on the natural trigger, the GH it produces is the body's own.

Pulsatile GH release, preserved feedback

Unlike injected HGH, which delivers a flat external dose, tesamorelin stimulates GH in the pulses the body normally uses. The somatostatin feedback loop that limits GH stays in place, so the release pattern is closer to physiological. Researchers point to this preserved feedback as a defining feature of the GHRH-analog class.

IGF-1 elevation and lipid metabolism

The growth hormone released downstream raises IGF-1 and acts on lipid metabolism. Published clinical research has reported that daily tesamorelin reduces visceral adipose tissue (VAT) over several months while raising IGF-1, which is the most-studied outcome of the compound.
