Tesamorelin

Tesamorelin peptide (TH9507): a stabilised GHRH analogue for research in Australia and New Zealand

Tesamorelin is a stabilised analogue (a lab-made copy) of growth hormone-releasing hormone (GHRH), a research peptide catalogued as TH9507 and also called Modified GRF (1-44). The molecule is a 44-amino-acid chain based on the natural growth hormone-releasing factor, GRF(1-44), reworked so it breaks down more slowly. GreenLabs AU stocks the Tesamorelin peptide for research teams in Australia and New Zealand as a white freeze-dried (dried-to-powder) vial, placed in our Growth Hormone Research Peptides range and offered for in-vitro (test-tube) study only, not for use in people or animals.

Tesamorelin peptide: key facts

• The compound: a GHRH analogue, a lab stand-in for growth hormone-releasing hormone, supplied as the acetate salt (tesamorelin acetate) and also listed as TH9507 or Modified GRF (1-44).
• Purity: above 98% by HPLC, most recent batch 98.12%, verified by the independent lab Janoshik, with a CoA per batch.
• Size and price: a 10mg vial, $90 to $120, as a vial alone or paired with a starter kit.

Understanding the Tesamorelin peptide, a GHRH analogue

Tesamorelin has a straightforward make-up. It is a lab-made (synthetic) chain of 44 amino acids (the small units that join to form proteins), modelled on the natural growth hormone-releasing factor, GRF(1-44). The single change is a trans-3-hexenoyl group fixed to one end; this acts as a shield that slows how quickly the peptide is broken down, giving it a longer working life in the lab than plain GRF. It is not a steroid, and it targets the GHRH receptor, the spot on a cell where growth hormone-releasing hormone attaches.

Tesamorelin in the research laboratory

In the lab, Tesamorelin acts as a standard GHRH analogue for research into growth hormone. Common in-vitro studies watch how it attaches to the GHRH receptor carried by pituitary cells (the pituitary gland directs growth hormone), how it sets off the release of growth hormone in cell models, and its part in fat-handling and IGF-1 pathways (IGF-1 is a signal tied to growth) in lab-grown cells. All of it stays at the cell and tissue level and makes no claim about a living body.

Comparing Tesamorelin with related growth hormone peptides

On the GreenLabs AU growth hormone shelf, Tesamorelin is usually compared with its closest relatives. Sermorelin and CJC-1295 sit closest, since both are GHRH analogues that reach the same GHRH receptor. It is also weighed against Ipamorelin, a GHRP (a different type of growth hormone peptide) that triggers growth hormone release by a separate route. Each pair is studied in-vitro, a standard way to compare how they work.

How we test Tesamorelin: purity and the CoA

For a research peptide, purity is what counts most, so GreenLabs AU sends each Tesamorelin batch to Janoshik, an independent outside lab. Testing uses HPLC (high-performance liquid chromatography, a method that pulls a sample apart to measure how much is the intended compound), and the reading comes in above 98%, with the newest batch at 98.12%. That batch’s Certificate of Analysis (CoA, the lab’s signed summary) goes up on our certificate page, ready to check against the vial in your hands.

Tesamorelin is supplied for research use only

In some countries Tesamorelin exists as an approved medicine, but what we ship is not that. It is a laboratory compound, nothing more. GreenLabs AU Tesamorelin carries no TGA registration (the TGA, or Therapeutic Goods Administration, oversees medicines in Australia), nor any similar approval overseas, for application to or inside the body, and none of this text is medical advice. We sell it only to qualified researchers who will work with it under correct lab conditions and within all applicable Australian and New Zealand laws.

Buy Tesamorelin peptide online in Australia and New Zealand

• Order the Tesamorelin peptide online from GreenLabs AU, an Australian-owned supplier with local stock, as a single Tesamorelin 10mg vial from $90 to $120, or scale up with the 10x bulk pack (100mg).
• Just getting set up? Choose the vial with a Starter Kit and the main supplies for mixing the powder arrive together.
• Orders placed before 12pm AEST leave Sydney the same business day by tracked Australia Post Express. Delivery usually takes about 2 to 4 business days for metro (city) Australia, 3 to 5 for regional areas, 4 to 6 for WA (Western Australia), and 4 to 6 to New Zealand.
• Spend over $200 and express shipping is free, with a flat $14.95 rate under that.

Storing and preparing Tesamorelin

• Store the sealed vial somewhere cool, dark and dry, under 25°C; for longer storage, a freezer around -20°C is best.
• To reconstitute (turn the dry powder back into liquid), pour bacteriostatic water (sterile water with a mild preservative that holds back bacteria) slowly down the vial wall.
• Once mixed, keep it chilled, use it inside a few weeks, and keep freeze-thaw cycles (rounds of freezing and thawing) low, since repeating that too often can break it down.
• Expect a clear, colourless liquid; set aside any vial that turns cloudy or shows particles.

Tesamorelin: frequently asked questions

What is the Tesamorelin peptide?

Tesamorelin is a lab-made GHRH analogue, a stand-in for the body’s own growth hormone-releasing hormone. It is a peptide (a short chain of amino acids) made of 44 amino acids, also written as TH9507 or Modified GRF (1-44). GreenLabs AU sells it as a freeze-dried powder for test-tube (in-vitro) research.

What is Tesamorelin studied for in research?

Researchers use it as a standard GHRH analogue at the lab bench. They study how it acts on pituitary cells (the small gland that drives growth hormone) and how it affects the way cells handle fat, all in lab-grown cells. This is test-tube work only, and not for people or animals.

What is the difference between Tesamorelin and Sermorelin?

Each one copies growth hormone-releasing hormone and acts on the same spot on the cell, the GHRH receptor. Sermorelin is a shorter form, GRF (1-29). Tesamorelin is a longer, more stable form, GRF (1-44), that lasts longer in lab conditions. The two are often compared in research.

How pure is GreenLabs AU Tesamorelin, and do I get a CoA?

The independent lab Janoshik measured 98.12% on the most recent batch, comfortably over 98%, by HPLC (a lab purity test). You can find that batch’s signed Certificate of Analysis (CoA) on our certificate page, and a copy is included in every order.

How is Tesamorelin stored and reconstituted?

Store the sealed vial somewhere cool, dark and dry under 25°C, or in a freezer near -20°C for longer storage. To get it ready, mix the powder with bacteriostatic water, keep the mix cold, and avoid freezing and thawing it again and again.

What size and price does Tesamorelin come in?

GreenLabs AU offers Tesamorelin as a 10mg vial, on its own or together with a starter kit, priced from $90 to $120. A 10x bulk pack is also available.

Where can I buy Tesamorelin in Australia and New Zealand?

Buy it online from GreenLabs AU. We keep stock in Australia and ship to both Australia and New Zealand, so there is no need to find a local shop or search “near me”.

Is Tesamorelin approved for human, medical or veterinary use?

No. GreenLabs AU supplies Tesamorelin only as research material for the lab. It is not a medicine, a cosmetic or a supplement, and it should never go on or into people or animals.

Disclaimer: GreenLabs AU provides Tesamorelin strictly for in-vitro laboratory research.
