Tesamorelin

Neurogen Research Tesamorelin (TH9507): a GHRH-analogue peptide stocked for Australian and New Zealand labs

Neurogen Research supplies Tesamorelin as a research-grade GHRH analogue (a lab-made form of growth hormone-releasing hormone, or GHRH) for laboratories across Australia and New Zealand. It carries the development code TH9507 and the chemical name Modified GRF (1-44). The peptide is a chain of 44 amino acids, built from the same GRF(1-44) the body makes naturally, with one small change that slows how fast it breaks down. We list the Tesamorelin peptide under Growth Hormone Research Peptides and send it out as a freeze-dried (dried to a powder) vial, strictly for in-vitro (test-tube) study and never for people or animals.

What the Tesamorelin peptide is made of

Tesamorelin is a lab-made (synthetic) string of 44 amino acids (the tiny building blocks that link up into proteins), copied from the GRF(1-44) that the body produces. The one addition is a trans-3-hexenoyl group joined to one tip of the chain; it behaves like a protective cap, slowing how fast the peptide is taken apart so it survives longer on the bench than plain GRF. Tesamorelin is not a steroid, and its docking point is the GHRH receptor, the place on a cell that normally receives growth hormone-releasing hormone.

The Tesamorelin peptide at the research bench

At the bench, Tesamorelin serves as a well-known GHRH analogue for growth hormone work. In-vitro experiments typically follow how it attaches to GHRH receptors on the surface of pituitary cells (these cells sit in the pituitary, the gland that steers growth hormone), how it triggers growth hormone release in lab-grown cells, and the way it feeds into fat-handling and IGF-1 signalling (IGF-1 is a growth-linked messenger) in those same cells. Everything here stays at the level of cells and tissue, and none of it speaks to what happens inside a living body.

Tesamorelin versus other growth hormone peptides

Within the Neurogen Research growth hormone range, Tesamorelin is most often set next to its closest cousins. The two nearest are Sermorelin and CJC-1295: like Tesamorelin, both are GHRH analogues working through the GHRH receptor. A separate comparison puts it next to Ipamorelin, a GHRP (a different class of growth hormone peptide) that drives growth hormone release along its own route. Each of these pairings is run in-vitro, a common way to map where the compounds differ.

Tesamorelin purity: third-party testing and the CoA

For any research peptide the purity figure matters most of all, so Neurogen Research sends every Tesamorelin batch to the independent lab Janoshik. The check is done by HPLC (high-performance liquid chromatography, a technique that splits a sample apart to measure what share of it is the intended compound), and the reading lands above 98%, the latest batch at 98.12%. We post the Certificate of Analysis (CoA) for that batch, the lab’s signed result sheet, on our certificate page, so you can line it up against the vial you receive.

Tesamorelin is a research material, not a medicine

In a few countries Tesamorelin is an approved medicine; the vial we ship here is something else entirely. It is bench material and nothing else. Neurogen Research Tesamorelin holds no registration with the TGA (the Therapeutic Goods Administration, the authority for medicines in Australia), nor with any similar regulator abroad, for use on or inside the body, and nothing written here is medical advice. We sell it only to trained researchers who will work with it safely in the lab and keep to all Australian and New Zealand laws that apply.

Buy Tesamorelin 10mg from Neurogen Research (Australia and New Zealand)

• Order Tesamorelin 10mg direct from Neurogen Research, an Australian-owned brand that holds stock locally, as one vial at $109 to $139, or move up to the 10x bulk pack (100mg) for larger projects.
• Setting up your bench? Pick the vial together with a Starter Kit so the main mixing supplies land in the same parcel.
• If your order is in before 12pm AEST, it ships out of Sydney the same business day on tracked Australia Post Express. As a rough delivery guide, allow 2 to 4 business days for city Australia, 3 to 5 for regional, 4 to 6 for Western Australia (WA), and 4 to 6 for New Zealand.
• Spend above $200 and express shipping costs nothing; below that it is a flat $14.95.

Storing Tesamorelin and mixing it for use

• Store the unopened vial in a cool, dry, dark place below 25°C; for long-term holding, a freezer at roughly -20°C is ideal.
• To reconstitute (bring the dry powder back to a liquid), add bacteriostatic water (sterile water holding a gentle preservative that keeps bacteria in check) slowly, letting it slide down the inner glass of the vial.
• Once it is mixed, keep it in the fridge, use it up within a few weeks, and limit how often it is frozen and thawed, since repeating that wears the peptide down.
• A clear, colourless liquid is what you want; hold back any vial that goes cloudy or shows floating bits.

Tesamorelin technical specifications

Frequently asked questions about Tesamorelin

What is the Tesamorelin peptide?

The Tesamorelin peptide is a synthetic copy of growth hormone-releasing hormone, the kind researchers call a GHRH analogue. Chemically it is built from 44 amino acids (the small blocks that form proteins), and it also goes by TH9507 or Modified GRF (1-44). Neurogen Research supplies it as a dried powder for in-vitro (test-tube) work.

What is Tesamorelin studied for in research?

At the bench it serves as a reference GHRH analogue. Researchers watch how it behaves with pituitary cells (the gland that steers growth hormone) and how it ties into fat-handling pathways in cells grown in the lab. All of this is cell-level work, done in the lab rather than in any living thing.

What is the difference between Tesamorelin and Sermorelin?

They each copy growth hormone-releasing hormone and work at the GHRH receptor. The difference is mostly length: Sermorelin is the shorter GRF (1-29), and Tesamorelin is the longer GRF (1-44) with one added group that helps it stay stable for longer during lab work. The two are a frequent pairing in research.

How pure is Neurogen Research Tesamorelin, and do I get a CoA?

Janoshik, our independent testing lab, put the newest batch at 98.12%, comfortably past the 98% mark, measured by HPLC (a method that checks purity). The signed Certificate of Analysis (CoA) for that batch is on our certificate page, and a printed copy comes inside your parcel.

How is Tesamorelin stored and reconstituted?

Hold the sealed vial in a cool, dark, dry spot under 25°C, and move it to a freezer around -20°C if you need to keep it longer. To prepare it for study, combine the powder with bacteriostatic water, store the mixed liquid chilled, and limit how often you freeze and thaw it.

What size and price does Tesamorelin come in?

You can get Tesamorelin here as one 10mg vial, either by itself or paired with a starter kit, priced $109 to $139. There is a 10x bulk pack too for bigger projects.

Where can I buy Tesamorelin in Australia and New Zealand?

You can order online, straight from Neurogen Research. We hold our stock in Australia and post to addresses right across Australia and New Zealand, which means no shop to visit or “near me” search to run.

Is Tesamorelin approved for human, medical or veterinary use?

No. Neurogen Research treats Tesamorelin only as laboratory research stock. It is not a medicine, not a cosmetic and not a supplement, and it should never be put on or into a person or an animal.

Disclaimer: Neurogen Research sells Tesamorelin for in-vitro laboratory research alone. It is not a medicine, a supplement, a cosmetic or a skincare item, and it is never to be used on or within humans or animals. Placing an order is your confirmation that you work as a qualified researcher and will keep the material’s storage, handling and use within every Australian and New Zealand law that applies.
