Tesamorelin

Tesamorelin is a synthetic 44-amino-acid analog of growth-hormone-releasing hormone (GHRH), stabilised by an N-terminal modification. It has the molecular formula C221H366N72O67S, a molecular weight of 5135.9 g/mol and CAS number 218949-48-5, also coded TH9507. Kyrolabs supplies it as a lyophilised research chemical for laboratory research use only, not for human or veterinary use.

Tesamorelin is not a controlled drug under the Misuse of Drugs Act 1971 and is not scheduled in the UK. Kyrolabs supplies it for laboratory research use only; it cannot be sold or labelled for human or veterinary consumption. It is not a licensed medicine in the UK. The buyer is responsible for compliant, lawful handling and for any institutional requirements that apply to their work.

No. Tesamorelin from Kyrolabs is supplied strictly as a research chemical for laboratory research use only. It is not intended, labelled or sold for human or veterinary use, ingestion or administration of any kind. Buyers must handle it as a reference compound for non-clinical bench work and not for use in or on the body.

Tesamorelin is a peptide: a synthetic 44-amino-acid analog of growth-hormone-releasing hormone. It is not a steroid and not a small-molecule drug. Its peptide identity is reflected in the molecular formula C221H366N72O67S and molecular weight of 5135.9 g/mol, with CAS number 218949-48-5 and PubChem CID 16137828 for cross-referencing.

Tesamorelin has the molecular formula C221H366N72O67S and a molecular weight of 5135.9 g/mol. Its CAS number is 218949-48-5 and its PubChem CID is 16137828. It is also known by the development code TH9507. These identifiers let a laboratory confirm the reference material against public chemical databases on receipt.

No. Purity and identity vary between suppliers, which is why a Certificate of Analysis matters. Kyrolabs releases each batch against an independent CoA with purity assessed by HPLC at 99% or greater and identity confirmed against the expected mass for C221H366N72O67S. Batch documents are published on our Certificates of Analysis page so the material can be verified.

Tesamorelin is supplied at 99% or greater purity by HPLC, with identity confirmed against the expected mass for the molecule. Every batch carries an independent Certificate of Analysis covering purity and identity, and these documents are available on our Certificates of Analysis page. The CoA is the reference for confirming what was received.

Tesamorelin is supplied as a white to off-white lyophilised powder sealed in a vial. For bench work it is reconstituted with a research-grade solvent such as bacteriostatic water, which Kyrolabs stocks. The vial milligram strength is a product specification, not a usage instruction. Reconstitution here refers only to a laboratory preparation step, not to any use in or on the body.

Store the lyophilised solid at -20C, kept dry and protected from light, where it is stable long term. Once reconstituted, hold the material at 2-8C and keep it cold. Minimise freeze-thaw cycles and protect from light to preserve integrity for laboratory research. Storage guidance applies to the reference compound, not to any human application.

Yes. Kyrolabs supplies Tesamorelin in the UK as a research chemical for laboratory research use only, with UK despatch and a Certificate of Analysis for each batch. It is sold strictly as a reference compound for non-clinical research and not for human or veterinary use. The buyer is responsible for lawful, compliant handling of the material.

All three are GH-axis research peptides supplied by Kyrolabs, but they are distinct molecules with different sequences and identifiers. Tesamorelin is a stabilised 44-amino-acid GHRH analog (CAS 218949-48-5); Sermorelin and CJC-1295 DAC are separate compounds with their own CoAs. This comparison describes what the molecules are, not any effect; see the GH-axis category to compare the reference materials.

TH9507 is a development code for Tesamorelin, the same synthetic GHRH analog with molecular formula C221H366N72O67S, molecular weight 5135.9 g/mol and CAS number 218949-48-5. If a supplier lists TH9507, it refers to this molecule. Kyrolabs supplies it as a lyophilised research chemical for laboratory research use only.
