Tesamorelin's single 44-amino-acid chain carries a short fatty group at its start, and is studied in the laboratory at the same receptor the natural hormone binds. This is the 20 mg Tesamorelin vial, the larger of two, listed as 93548.
Nothing is published for the 20 mg size yet — Tesamorelin lots are independently lab-tested, and the certificate follows.
In vitro growth hormone axis research purposes only. Australian Research Peptides does not supply Tesamorelin for human or veterinary use.
Tesamorelin is an analogue of growth-hormone-releasing hormone, usually shortened to GHRH. An analogue copies the structure of another molecule but changes one part of it. GHRH is the body's own natural signal for the GHRH receptor (its endogenous ligand), and tesamorelin is a longer-lasting analogue of that signal. Laboratory work studies it at that receptor.
Each vial holds the full 44-amino-acid chain of human GHRH, plus a hex-3-enoyl group on the tyrosine at the N-terminal end, which is the part the natural hormone doesn't have. Published records say this end was modified to make the molecule more stable. Length is what separates tesamorelin from Australian Research Peptides' other growth-hormone listing: the CJC-1295 vial holds a shorter 29-amino-acid fragment analogue instead.
Australian Research Peptides holds tesamorelin as a laboratory reference material for in vitro work in glassware and cell culture. Each lot is independently lab-tested before release, and the CoA library names the strengths a certificate has been published for. It is not supplied for use in people or animals, and Australian Research Peptides makes no claim about what it does in either.
Tesamorelin is listed in two strengths, a 10 mg and a 20 mg vial of the same freeze-dried powder, each with its own page and stock code, and people search for it as tesamorelin, tesamorelin peptide, tesa, tesamorelin 10 mg or tesamorelin 20 mg, all of which mean the same GHRH analogue. Orders are posted from within Australia, so none waits on an overseas shipment or an import step.

Questions about Tesamorelin 20 mg
These Tesamorelin 20 mg questions from Australian Research Peptides cover this exact vial first — live price, stock and delivery, the value against two 10 mg vials and the bundle question — then storage, testing and the background shared with the other strength.
Quick answers
Australian Research Peptides (ARP) sells Tesamorelin 20 mg in Australia under 93548, at $259.99. Standard tracked post and Express Post carry Tesamorelin 20 mg to all states and territories.
Twenty milligrams of freeze-dried tesamorelin, the 44-amino-acid peptide, sit under one seal in the 20 mg Tesamorelin vial, twice the fill of the 10 mg vial. No diluent is included, and the 20 mg has its own stock code, separate from the 10 mg.
Tesamorelin 20 mg costs $259.99 a vial (stock code 93548) at Australian Research Peptides, and two 20 mg Tesamorelin vials come to $519.98.
Two 10 mg Tesamorelin vials cost $279.98; one 20 mg vial is $259.99 — $19.99 less, and one fewer vial to store.
Tesamorelin batches from Australian Research Peptides are independently lab-tested, at a laboratory commissioned by the manufacturer, before release, and any published certificate of analysis is filed in the CoA library and linked from the listing. A certificate records identity and measured purity for one named batch, and its figure belongs to that batch, not to the listing as a whole. No matching certificate is currently published for this product and strength.
No, Tesamorelin 20 mg is not in the Retatrutide + Tesamorelin Bundle or the Reta + Tesa + MOTS-C Bundle: both kits hold the 10 mg Tesamorelin vial, and their contents are fixed. The 20 mg is sold as a single vial only.
Exact strength, quantity and listing fit
Yes, the 20 mg Tesamorelin vial holds the same compound as the 10 mg, the full 44-amino-acid GHRH chain with its short fatty hex-3-enoyl group, at the same grade. Only the amount and the stock code differ, and each strength is tested lot by lot.
Per milligram, Tesamorelin 20 mg works out to about $13.00 — $259.99 across 20 mg. The 10 mg Tesamorelin vial works out to about $14.00 a milligram.
Yes, one 20 mg Tesamorelin vial is simpler to handle than two 10 mg vials: one seal to open, one reconstitution to make and one lot number to record, against two of each. Each page's live per-milligram price settles the cost side.
The 20 mg Tesamorelin vial suits longer series of GHRH-receptor work, multi-arm studies or repeated assays where one vial and one lot should cover the whole run. Once mixed, all 20 mg is in solution, so staged work may suit the 10 mg better.
Live price, stock and Australian buying
On Standard tracked post, yes. One Tesamorelin 20 mg vial at $259.99 passes $199 unaided. Free Express Post starts at $299, which this vial misses by $39.01.
$259.99 delivered in Australia. Tesamorelin 20 mg is $259.99, over $199, so 93548 posts free by Standard tracked post. Express Post makes 93548 $276.98.
Two vials of Tesamorelin. At $259.99 each, two 20 mg vials make $519.98 — past $299, so 93548 ships free by Express Post, costing $519.98.
Reconstitution and concentration calculations
To reconstitute Tesamorelin, you turn its freeze-dried powder into a solution with a suitable diluent, letting the sealed vial reach room temperature first. Run the liquid down the inside wall of the vial rather than dropping it straight onto the dry powder. Roll or swirl gently, never shake, and keep the solution chilled once it is made.
Australian Research Peptides publishes no fill volume for 93548, so the amount is a decision for the work rather than one the listing sets. 93548 is 20 mg of dry Tesamorelin: what the diluent changes is the solution, never the 20 mg sealed in the glass.
A 20 mg Tesamorelin vial needs twice the diluent of a 10 mg vial for the same concentration, because it holds twice the peptide. Neither label implies a set volume: the laboratory picks the volume, and that choice alone decides how strong the solution is.
Tesamorelin usually looks cloudy after mixing because it was shaken or swirled too hard, which is why the vial should be rolled gently instead. Shaking drives air through the liquid, which shows as a milky haze that clears when the vial is left to stand. Cloudiness that doesn't clear, or particles left after the powder seems to have dissolved, means the solution isn't sound.
Product identity and research background
Tesamorelin is a synthetic, full-length analogue of human growth-hormone-releasing hormone (GHRH), made of 44 amino acids with a hex-3-enoyl group at its N-terminal end. It is studied in endocrine research on the growth-hormone axis, the chain of signals that controls when growth hormone is released. Research covers how it binds the GHRH receptor in cell culture and other in vitro models. Australian Research Peptides supplies it for in vitro laboratory work and claims no effect for it.
The hexenoyl group on Tesamorelin, written hex-3-enoyl, is a short fatty chain attached to the tyrosine at the N-terminal end, and LiverTox records that it was added for stability. Changing that end of the molecule helps the peptide hold up better in handling and storage. That is a fact about the molecule, not a claim about any effect. Without it, what is left is the plain GHRH sequence.
Tesamorelin contains 44 amino acids, the complete chain of human growth-hormone-releasing hormone rather than a shortened piece, which is why it is called a full-length sequence. That count covers the peptide chain only. The hex-3-enoyl group at one end is a fatty acyl group, not an amino acid, so it isn't part of the 44. This page doesn't publish the sequence residue by residue.
Tesamorelin is also known by its development code, TH9507, sometimes written with a hyphen as TH-9507, and the literature often calls it simply a full-length GHRH analogue. Chemical registries list it as N-[(3E)-hex-3-enoyl]tyrosyl hGRF(1-44) amide. Australian Research Peptides links the shorthand tesa to this listing, and the name is often misspelled as tesamorilin. Whichever name you searched, the vial ships from inside Australia, so nothing waits on customs.
Australian Research Peptides hasn't confirmed whether its Tesamorelin vial holds tesamorelin acetate, the acetate salt of the same 44-amino-acid GHRH analogue, so the listing doesn't call it the acetate. Both forms contain the identical peptide with a different counter-ion, and they have separate registry numbers: CAS 218949-48-5 for the free base and 804475-66-9 for the acetate. Because the form is unconfirmed, the molecular formula and mass also stay out of the specification table, since both differ between the two forms.
Storage, condition and testing
Yes, Tesamorelin needs cold storage once you take delivery, but not during transit, because sealed freeze-dried peptides handle normal postal temperatures, which is why the vial travels without a cold chain. Cold storage matters most once the powder has been dissolved. A Tesamorelin vial that arrives warm but still sealed has not spoiled.
Yes, it is normal for a Tesamorelin vial to look empty, because ten or twenty milligrams of off-white freeze-dried powder barely coats the bottom, even though the molecule is a long 44-amino-acid chain. Freeze-drying removes everything from a frozen solution except the solids. Movement in the post can also break the cake into dust that spreads up the walls, making the vial look untouched.
Tesamorelin should be stored as a sealed, freeze-dried powder at -20 °C, protected from light and moisture, which is the condition Australian Research Peptides states for the dry vial. Once dissolved, store it at 2-8 °C, where it lasts 8 to 12 weeks. Don't refreeze a solution that has thawed. A short warm spell in transit is normal for freeze-dried material.
Once mixed, Tesamorelin lasts eight to twelve weeks stored at 2–8 °C, which is the condition Australian Research Peptides states for reconstituted material. At 44 amino acids, Tesamorelin is the longest chain in the catalogue, and more amino acids mean more bonds that water can break down. Its hex-3-enoyl cap was added for stability, but that is a separate question from how the peptide holds up in solution.
Delivery, payment and access questions
Tesamorelin usually arrives in 1–2 business days by Express Post to most destinations, or 2–5 business days by standard tracked post, counted from when the parcel is lodged, not from checkout. A tracking number is emailed as soon as the parcel goes to the carrier, not when the order is placed, so the time between the two is dispatch, not a delay. If tracking hasn't updated for two business days, contact support.
You can pay for Tesamorelin by PayID or by bank transfer from your own account, and wallets and cryptocurrency are not accepted. For PayID or bank transfer, put the unique order reference in the payment description, because that reference is how the payment is linked to your Tesamorelin order. Payments are matched by hand, so a transfer without the reference has to be matched by name and amount, which delays dispatch and occasionally can't be sorted out at all.
Tesamorelin is sold in Australia to laboratories and researchers for in vitro research purposes only, never as a medicine, and Australian Research Peptides does not supply it as a therapeutic good, a supplement or a food. It is not intended for human or animal use. Any figure given alongside Tesamorelin describes the vial or the solution made from it, never an instruction for a person.
Tesamorelin is for laboratories, universities and independent researchers working on the growth-hormone axis, and Australian Research Peptides supplies it for in vitro research in glassware and cell culture only. It is a research compound, not a therapeutic good or a supplement. Australian Research Peptides doesn't sell it to members of the public for personal use and publishes no usage guidance for it.
Yes, Tesamorelin is banned in sport, named on the WADA Prohibited List among the growth-hormone-releasing hormone analogues in section S2.2, beside sermorelin and CJC-1295, and prohibited at all times. Sport Integrity Australia administers the list in Australia. Australian Research Peptides doesn't rule on any compound's status in sport, and supplies Tesamorelin only to laboratories and researchers for in vitro research.
No, Tesamorelin is not sold at Chemist Warehouse or any other Australian pharmacy, and it isn't available over the counter, because it is a laboratory research compound, not something a pharmacist dispenses. Australian Research Peptides sells Tesamorelin online in 10 mg and 20 mg vials of freeze-dried powder, supplied to laboratories and researchers for in vitro research only.
