In brief: ALTA PEPTIDES supplies Tesamorelin (GHRH(1-44) analogue) as a 10 mg lyophilised vial for £59.99 (£6.00/mg), tested per lot by an independent UK laboratory with the certificate of analysis published, held in UK stock and dispatched the same working day before 1pm. Supplied for laboratory research only, not for human consumption.

What is tesamorelin?

Tesamorelin is a 44-amino-acid analogue of growth hormone releasing hormone with a trans-3-hexenoyl group on the N-terminus that protects it from enzymatic breakdown. It is the most thoroughly studied GHRH analogue in humans and is licensed in the United States (as Egrifta) for a specific indication in HIV patients; it is not licensed in the UK or EU. Supplied here at 99%+ HPLC purity in 10 mg sealed vials for laboratory research.

What the research covers

Large controlled trials report increased pulsatile growth-hormone secretion and IGF-1, and reductions in visceral adipose tissue, with adverse effects including injection-site reactions, joint pain and changes in glucose tolerance. It is the reference compound against which other GHRH analogues and secretagogues (sermorelin, CJC-1295, ipamorelin) are compared.

Buying tesamorelin in the UK

The tesamorelin peptide is held in UK stock as a lot-tested 10 mg lyophilised vial, tested by an independent UK laboratory with the certificate of analysis published before release, and dispatched the same working day before 1pm. Supplied strictly for laboratory research.

Tesamorelin vs ipamorelin

Different mechanisms: tesamorelin is a GHRH analogue acting at the GHRH receptor; ipamorelin is a ghrelin-receptor agonist (a secretagogue). They are studied together because they act on the same axis by different routes.

Legal position

Not controlled in the UK. Licensed as a prescription medicine in the USA, which makes it a medicine by function here; unlicensed in the UK. WADA-prohibited (S2). Listed only with written legal advice and supplied strictly as a laboratory reagent.

Quality and testing

Each lot of Tesamorelin is sent to an independent UK laboratory before release for identity by mass spectrometry, purity by HPLC, residual solvents and bacterial endotoxin. The lot number on the vial label matches the certificate on our certificates page, and no lot is released for sale until the certificate is in hand. Specification: ≥ 99% (HPLC), supplied as lyophilised powder, 3 ml glass vial, sealed, 10 mg per vial.

Reconstitution and handling

Tesamorelin arrives as a lyophilised cake under an aluminium crimp seal. Let the vial reach room temperature before opening so that condensation does not form on the powder. Swab the stopper with an alcohol swab, draw the chosen volume of bacteriostatic water with a sterile syringe, and add it slowly down the inside wall of the vial rather than onto the powder. Swirl gently until clear; never shake, which can denature the peptide. Label the vial with the date and concentration. The peptide calculator converts vial amount and diluent volume into concentration, millilitres and U-100 syringe units for any target amount. Sealed vial: 2 to 8 °C, protected from light. Reconstituted: 2 to 8 °C, use within 2 weeks.

Lot traceability

Every Tesamorelin vial carries a printed lot number and expiry. The same lot number appears on the certificate of analysis for that batch, which names the testing laboratory and the report number so it can be verified directly. If the number on your vial does not match a certificate on our site, contact support before using it. Certificates are kept online for the life of the product plus two years.
