Prices for Tesamorelin start at £31.99 for the 10mg vial, and all of it is already in British stock at diluents.co.uk rather than sourced to order. It is offered as vial. Order on a weekday before 2pm and the parcel leaves that day, tracked, in a box that gives no clue to its contents.

Because the parcel never leaves the country, nothing has to clear customs, no import charge falls due and nothing is held at a border. Each batch tests at ≥99% by HPLC, and a certificate of analysis for the stock you receive is available on request.

Tracked delivery costs £4.95, or nothing above £75. The ordering steps, one by one.

What is Tesamorelin?

Developed as TH9507, tesamorelin is a synthetic analogue of growth hormone-releasing hormone. As licensed medicines it is marketed as Egrifta and Egrifta SV, for excess abdominal fat in HIV-associated lipodystrophy. Our material carries no part of that licence; it is an unlicensed research compound.

Buying Tesamorelin in the UK: where and how

How does ordering work?

Choose a strength, add it to the basket and go through checkout; no account is needed. An order confirmation comes through at once, and since the site never takes a card, the payment details arrive separately by email.

What difference does UK stock make?

Your Tesamorelin is sent from a warehouse in Britain, so it skips customs, attracts no import charge and loses no days travelling from overseas. A courier collects it the same afternoon if the order is in before 2pm on a working day; the parcel then travels tracked in a plain outer box.

What do you receive?

Tesamorelin reconstitution

What ships is a dry, freeze-dried cake, and bacteriostatic water is what turns it into a solution. The volume you choose sets how strong that solution ends up. Water only spreads the contents out; it never adds to or takes from the milligrams sealed in the vial.

5.00 mg/mlConcentration
0.100 mlHolds 0.5mg
10.0 unitsOn a U-100 syringe
50 mcgPer unit of that syringe

The figures above are volumes and concentrations of a solution; none of them is a dose, and no guidance on dosing, protocols or administration is given on this site.

The figures open on the 10mg vial with 2ml added, and they update as soon as either control changes. For the syringe-scale conversion, a comparison of the waters and the keeping time of a mixed vial, use the full reconstitution calculator.

mg/ml reached for each vial size and volume of water
Vial+ 1ml+ 2ml+ 3ml+ 5ml
10mg 10 mg/ml5 mg/ml3.33 mg/ml2 mg/ml

As a worked case, the 10mg vial with 2ml of bacteriostatic water comes to 5 mg/ml, which is simply the label milligrams divided by the millilitres added. Every number in the table is the concentration of a solution, never a dose. Dosage, protocol and administration guidance appear nowhere on this site.

What care does the vial need?

  • A chilled vial should warm to room temperature first.
  • Before every entry through the stopper, clean it with an alcohol swab.
  • Let the water run down the inside wall of the glass; never squirt it onto the cake.
  • Roll, never shake: foam means protein has been damaged, and rolling between the fingers avoids it.
  • Expect a few minutes before it dissolves fully; a correctly mixed vial ends up clear.

Tesamorelin storage

Vial, still sealedKeep it dark, dry and cool; the freezer suits long-term storage best.
After mixingRefrigerate it upright and shaded. A mixed solution should never be frozen.

What is its shelf life?

Typical keeping times for lyophilised peptides in general
ConditionTypical life
Unopened, in a −20 °C freezerYears. No other condition preserves a lyophilised peptide as well
Unopened, in a fridge at 2–8 °CMonths
Unopened, at room temperatureWeeks. It copes with the time in transit but should not be kept like this
Mixed, in the fridgeWeeks rather than months. With bacteriostatic water added, the usual working figure is four weeks, and making that possible is the job of its preservative
Mixed, then frozenNot recommended. Peptides are torn by ice crystals, and each freeze–thaw cycle compounds the damage

These are the standard figures for lyophilised peptides in general; no stability study on a single batch produced them. Time is gained by keeping it cold and dry, and lost to damp, warmth, light and rough handling. A certificate of analysis is available on request.

Here it is supplied strictly as an unlicensed compound for laboratory research use only. No UK marketing authorisation covers Tesamorelin and it is not a licensed medicine, nor is it intended for human or veterinary use, or for food.

Compounds of this kind are not controlled drugs, and they can lawfully be sold as laboratory material; it is selling or marketing them for use by people that the law does not allow. That boundary is why this site carries no dose, protocol, route, frequency or medical claim, and why an emailed request for one is declined as well.

Some molecules in this range are also present in a licensed medicine marketed under a brand name. Its authorisation covers only the finished product for which it was granted, not the molecule in any other setting. Read the full terms.

Research use only. Diluent is not a pharmacy, and none of its compounds is a licensed medicine: everything is sold for laboratory research, with no dosage, protocol or administration guidance given. Not intended for human or veterinary use, or for use in food.

Questions about Tesamorelin

Is tesamorelin licensed as a medicine?

As Egrifta and Egrifta SV it is, for one indication only. That authorisation attaches to those finished products; our unlicensed research compound has no share in it.

Which receptor is its target?

Its target is the GHRH receptor.

What does Tesamorelin do?

The Tesamorelin sold here is an unlicensed research compound, supplied for laboratory research only, and HPLC assay puts it at ≥99% purity. Further down this page you will find the full specification alongside the published studies.

Where in the UK can I buy Tesamorelin?

In the UK, diluents.co.uk supplies Tesamorelin in one 10mg size only, as vials, priced from £31.99. Nothing is drop-shipped from overseas: each order is picked from a UK shelf, and that is what lets it catch same-day dispatch. Per milligram, that works out at £3.20. Because it is supplied as freeze-dried powder, the concentration is whatever you choose when it is mixed. Orders placed before 2pm on a weekday go out the same day, tracked and in plain packaging. Each batch goes through third-party lab testing and returns an HPLC result of ≥99%; the certificate covering yours is available on request, and for the steps, see how to order.

What does Tesamorelin cost?

Prices begin at £31.99 with the 10mg, £3.20 a milligram. Delivery costs £4.95, and above £75 there is no charge at all.

How much bacteriostatic water goes into Tesamorelin?

That is up to you, since the volume added is what sets the strength. On the 10mg vial, 10 mg/ml comes from 1ml, 5 mg/ml from 2ml and 3.33 mg/ml from 3ml, while the 10mg of material inside does not change. Every one of these figures is a concentration and none is a dose.

How do you store Tesamorelin?

Unopened and dry, it lasts for years in a freezer at −20 °C, for months refrigerated at 2–8 °C and for weeks at room temperature; the colder and drier the conditions, the longer it keeps. Once mixed with bacteriostatic water it belongs upright in the fridge, where four weeks is the usual working figure. A mixed vial must never be frozen, because ice crystals rip peptides apart and every freeze–thaw cycle repeats the damage.

Is Tesamorelin FDA approved?

Our Tesamorelin is supplied strictly for laboratory research, as an unlicensed research compound and for no other purpose. No UK marketing authorisation covers the product we sell, so it is not a licensed medicine; it is also not for human or veterinary use. Nor are we a pharmacy.

Can I see a certificate for your Tesamorelin, and what purity is it?

Yes. HPLC puts it at ≥99%, and on request we send the certificate of analysis that matches the material in your order. To check where current stock stands before you place an order, just ask and we will tell you.
