Tesamorelin 10mg Vial

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. Because the body's own feedback loop stays in charge, GH and IGF-1 rise in a pattern closer to how they behave naturally. People use it for body composition, recovery, sleep, and as part of GH-optimization and longevity stacks.

In the published research, tesamorelin is best known for its effect on visceral adipose tissue: the deep abdominal fat that sits around the organs. Clinical studies have reported reductions in VAT over several months of daily use, alongside increases in IGF-1. This is the body of work that made tesamorelin one of the most-studied GHRH analogs.

ProPeptide supplies tesamorelin as a lyophilized 10mg vial that you reconstitute with bacteriostatic water using sterile technique. Product specifications and batch documentation are kept product-specific and current. The product is not a licensed medicine and is sold as a research peptide.

Specifications and documentation are kept product-specific and current.

Sealed lyophilized vial.

Each 10mg vial is lyophilized in a controlled environment and sealed with a crimp cap. Reconstitute with 2mL of bacteriostatic water using sterile technique for a 5mg/mL stock, where 20 units on a U-100 syringe equals 1mg. That gives clean, repeatable draws at the 1-2mg doses tesamorelin is typically used at.

Cold-chain insulated packaging keeps the vial in the +2 to +8°C range from our facility to your door, with ice packs for any leg of the trip that needs them.

Direct from ProPeptide.

Sourced and packed in our own facility. Not relabelled from a middleman. No clinic markups, no distributor margins, no mystery supply chains. We are adding batch-number printing directly to ProPeptide packaging; if you need a box-printed batch number with a matching published COA today, choose the Remedium Research Retatrutide product.

Works with your own GH system.

Tesamorelin is a releasing hormone, not a replacement. It prompts your 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.

Tesamorelin sits in the growth hormone secretagogue family, but these peptides do not all work the same way. Here is how it compares to the other common options, with recombinant HGH as a reference point:

The GHRH analogs work by prompting your own pituitary rather than replacing GH. Tesamorelin is the one with the deepest published clinical record on visceral fat specifically.

Tesamorelin is typically used once daily, most often in the evening on an empty stomach, since the body's natural GH release peaks during sleep. Reconstitute the 10mg vial with 2mL of bacteriostatic water using sterile technique. That gives a 5mg/mL stock where 20 units on a U-100 syringe equals 1mg.
