# Tesamorelin in Perth: Research Records and WA Status Updated 2026-11-06. Tesamorelin is a lab-made peptide that researchers study as a copy of GHRH, a brain signal that tells the pituitary gland to release growth hormone. This site read the October 2026 Poisons Standard, instrument F2026L01327, on 14 October 2026. It states no status for tesamorelin, in either direction. That is a hold, not a statement of permission in Western Australia. | | | | --- | --- | | Common name | tesamorelin | | Research code | TH9507 | | Signal it copies | GHRH (growth-hormone-releasing hormone) | | Peptide length | 44 amino acids with a hexenoyl group at the start (Clemmons et al., PLoS ONE, 2017) | | Poisons Standard | Instrument F2026L01327, read 14 October 2026.

The lab report on file covers a smaller vial size | Think of a doorbell. The ring calls someone to the door, but the ring and the person are two different things. Tesamorelin sits on the ring side. It copies a hormone message. Searching for tesamorelin in Perth puts one research name beside very different records: papers, a legal search, a lab report and a parcel. This page is part of [the Perth research peptides hub](/learn/peptides-perth). It keeps each record in its own lane. See also [peptides in Perth](/peptides-perth). That way you can see what each record can tell you and where it stops. Catalogue listing: [Buy Tesamorelin (research use only)](/shop/tesamorelin). ## Which research subject does "tesamorelin Perth" refer to? Tesamorelin is a lab-made peptide, also called TH9507. It is a changed copy of GHRH, the message the brain sends to the pituitary gland. Clemmons and colleagues (*PLoS ONE*, 2017) describe a chain of 44 amino acids with a small chemical piece, a hexenoyl group, added at the start. So a search for tesamorelin in Perth points first at a molecule with a research record. [The tesamorelin research guide](/research/tesamorelin) covers the science in more depth than this page. A receptor is a protein that receives a chemical message. Zhou and colleagues (*Nature Communications*, 2020) pictured natural GHRH locked onto its receptor. That study did not use tesamorelin. It shows how the natural message fits its receiver. [The tesamorelin hub](/learn/tesamorelin) sets out the same record in plain steps. This is a statement about the design of the molecule. It says nothing about any vial, any law or any lot. That is why the questions below come after this one. ## What can these records leave unresolved? Tesamorelin sits at the centre of four records. Each one answers one narrow question. The papers describe a molecule. The Poisons Standard record shows what this site holds for one instrument on one date. The lab report on file covers one vial size. The parcel record follows a handover. No record can answer the question that belongs to another. So this page reads them one at a time. It keeps each one inside its own section. Read the four records as separate documents. Each was written for its own purpose. A science paper cannot approve the supply of a material. A held legal question is not a yes. A lab report for one vial size cannot describe another. A parcel route cannot settle a question of law. None of these sentences is a new legal finding. They mark the limit of each record. ## Is tesamorelin legal in Western Australia? This page cannot say whether tesamorelin is legal in Western Australia. This site read the October 2026 Poisons Standard, instrument F2026L01327, on 14 October 2026. It holds the question open. Its wording is: "This page states no status for tesamorelin, in either direction." A hold is not a statement of permission. It is also not a ban. We have not checked the position since 14 October 2026. The reading covers one document on one date. A later edition may differ, and this page does not cover one. The Australian law hub records the same hold, so the two pages cannot disagree. [The WA scheduling explainer](/learn/peptides-perth/peptides-and-wa-law) sets out how national poisons rules reach state law. It cannot stand in for this dated reading. [The tesamorelin legal records page](/learn/tesamorelin/is-tesamorelin-legal-in-australia) lists the other records, such as the ARTG search and the sport rule. ## How do the TGA records sit beside the Poisons Standard hold? The two records answer different questions. On 14 October 2026, a keyword search of the TGA's public ARTG page found no match for tesamorelin or Egrifta. ARTG is the TGA's public register of approved goods. The search covers one public page and could miss a product listed under another name. The advisory that the Therapeutic Goods Administration issued on 13 April 2026 names five peptides as examples of unapproved products. Tesamorelin is not one of them. A missing name does not mean tesamorelin products are approved. The same advisory says a research-use-only label does not by itself change a product's regulatory status. It adds that state and territory laws may place further controls on the sale, supply and possession of unapproved peptide products. This page offers no legal advice and implies no exemption. For sport, the World Anti-Doping Agency's 2026 Prohibited List names tesamorelin in class S2.2.4. That is a sport rule. It is separate from the ARTG and from the Poisons Standard. ## What question does each tesamorelin paper address? Three papers support the research record on this page. Each answers a different kind of question. Clemmons and colleagues (*PLoS ONE*, 2017) describe the molecule itself. Zhou and colleagues (*Nature Communications*, 2020) show how natural GHRH fits its receptor. Stanley and colleagues (*Journal of Clinical Endocrinology and Metabolism*, 2011) measured hormone signals in blood. A paper about a molecule is not a test of any supplied lot. Each paper measures something different. That is why they sit side by side here. Clemmons is about the build of the molecule. Zhou is about the shape of a receptor. Stanley is about blood measures. This page reports no result figure from any of them. None of those numbers can tell you anything about a lot. A paper can show how a lock is built. It cannot show which key has been cut for it. ## What does the Tesamorelin material's paperwork actually record? The store's listing is Tesamorelin, a freeze-dried research reference, lot TESA-2506. The catalogue records storage at 2-8 C, protected from light. The independent lab report on file covers a smaller vial size. The catalogue says that report is not for the vial sold here. So read the lot, the compound and the amount on the label against any report you are shown. What a lot number can establish explains how a lot code points to one production run. A report describes only its named sample and stated tests. This page follows the catalogue's description of what the report covers. It has not independently opened that report. It makes no claim about release approval. The store sells this material as reference material for lab research only. It is not for people or animals. ## Which part of the Perth journey can a tracking record answer? Tracking can record a parcel's progress and an estimated delivery date. It does not establish identity, purity or legal permission. The store says every order leaves Perth, Western Australia, sent by Australia Post or CouriersPlease after payment has cleared. The packaging is plain, with nothing on the outside to say what is inside. A tracking email follows when the order is handed over. The dispatch and tracking record is the whole of what this page draws on for the journey. The route is domestic and online-only. There is no public counter or collection point. The route itself does not establish legal permission. Perth enters here as the place a parcel starts. Nothing here gives an address, opening hours or a place to visit. ## Comparison Four records, four questions. Each column is one record. Each row states what it is drawn from, the question it answers and the question it cannot answer. The table separates the records. It does not rank them or compare products. | Record detail | Research papers | Dated regulatory records | Lab report on file | Parcel tracking | | --- | --- | --- | --- | --- | | Drawn from | Clemmons et al., PLoS ONE, 2017; Zhou et al., Nature Communications, 2020; Stanley et al., Journal of Clinical Endocrinology and Metabolism, 2011 | Poisons Standard F2026L01327 read 14 October 2026; ARTG search 14 October 2026; TGA advisory, 13 April 2026 | The catalogue's description of a report for a smaller vial size | The store's shipping page: dispatch from Perth, tracking email after handover | | Question it answers | Which molecule the papers describe and what they studied | What this site holds on one date and what the regulator has said | Which vial size the report covers | Where a parcel is after handover | | Question it cannot answer | Whether any supply is approved, or what any lot contains | Whether a particular sale is allowed, or whether the position changed after the check date | What is in the vial sold here | What the contents are, which report applies, or what the law says | ## Frequently asked questions ### Does this site state a Poisons Standard status for tesamorelin? No, this site states no Poisons Standard status for tesamorelin. It read F2026L01327, the October 2026 instrument, on 14 October 2026 and holds the question open. Its wording is: "This page states no status for tesamorelin, in either direction." The hold is not a statement of permission. We have not checked the position since that day. ### Is TH9507 the same thing as tesamorelin? Yes, TH9507 is the research code for tesamorelin. The store lists the material as Tesamorelin, also known as TH9507. A research code names a molecule across the papers. The store listing names one shelf entry at one store. Neither identifies a batch. Lot TESA-2506 is the batch identifier on the listing. ### Does the lab report on file cover the tesamorelin vial sold here? No, the lab report on file does not cover the vial sold here. It covers a smaller vial size. The catalogue says the report is not for the vial sold here. Compare the lot, compound and amount on your label with any report you are shown. ### Has the TGA named tesamorelin in its peptide advisory? No, not in the advisory read for this page. The TGA advisory of 13 April 2026 names BPC-157, GHK-Cu, TB-500, retatrutide and CJC-1295 as examples of unapproved peptide products. The examples are not a full list. A missing name does not mean tesamorelin products are approved. ### Can a tracking link show what is inside a tesamorelin parcel? No, a tracking link cannot show what is inside a parcel. It follows the parcel after handover and gives a delivery estimate. It cannot show identity, purity or legal permission. The packaging is plain, with nothing on the outside to say what is inside. ## Citations - Clemmons DR, Miller S, Mamputu JC.. PLoS ONE. 2017;12(6):e0179538.
