Tesamorelin

Tesamorelin Product Overview Tesamorelin is a synthetic 44-amino-acid peptide analog based on the complete sequence of human growth hormone-releasing hormone, also known as growth hormone-releasing factor or GHRF. The molecule contains a trans-3-hexenoyl group attached to the N-terminal tyrosine residue. This structural modification has been investigated for its ability to increase resistance to enzymatic degradation compared with unmodified human GHRH. Each vial contains 10mg of lyophilized Tesamorelin intended for controlled laboratory investigation of GHRH-receptor activity, pituitary signalling and growth hormone-related research pathways. Product Specifications Product name: Tesamorelin Quantity per vial: 10mg Peptide length: 44 amino acids Peptide class: GHRH/GRF analog Structural modification: N-terminal trans-3-hexenoyl group attached to Tyr1 CAS number: 218949-48-5 Reference molecular formula: C221H366N72O67S Reference molecular weight: 5135.9 Da as the free-base equivalent Format: Lyophilized material Container: Single vial Structural Characteristics Tesamorelin incorporates the complete 44-amino-acid sequence of human GHRH rather than a shortened active fragment. Its N-terminal modification distinguishes it from endogenous GHRH and from shorter GHRH-related research peptides. Published analytical and receptor studies have examined how this modification affects peptide stability, enzymatic cleavage and interaction with the GHRH receptor. The modification does not make Tesamorelin identical to endogenous GHRH and the two materials should be treated as separate research compounds. Scientific Background GHRH is a hypothalamic signalling peptide associated with the regulation of pituitary somatotroph cells. Research involving Tesamorelin has examined GHRH-receptor binding, intracellular signalling and downstream growth hormone and IGF-1 pathway responses. These pathways form part of a complex endocrine signalling network. Experimental results may differ according to the biological model, peptide concentration, exposure conditions, analytical method and identity of the tested material. References to growth hormone release or downstream metabolic activity describe research mechanisms and experimental endpoints. They should not be interpreted as claims that this product produces a physiological or therapeutic effect. Potential Research Areas GHRH-receptor binding and activation Pituitary somatotroph signalling models Growth hormone and IGF-1 pathway research Comparative analysis of GHRH analogs Peptide stability and enzymatic degradation Receptor-response kinetics Endocrine and metabolic signalling models Analytical identity and purity testing Tesamorelin and Other GHRH-Related Peptides Tesamorelin is structurally distinct from Sermorelin, CJC-1295 and other GHRH-related research compounds. Differences in peptide length, amino-acid substitutions and terminal modifications can affect receptor interaction, stability and experimental behaviour. Results obtained with one GHRH analog should not be assumed to apply to another without direct comparative testing. Research Material and Pharmaceutical Tesamorelin Tesamorelin is also discussed in pharmaceutical literature under regulated product names. Those products have defined formulations, excipients, manufacturing controls and regulatory specifications. Data involving a regulated pharmaceutical formulation do not independently establish the identity, purity, quantity, sterility, safety or performance of this Nuforme research material. Researchers should use the documentation associated with the specific Nuforme batch when designing or interpreting experiments. Analytical Considerations The batch-specific Certificate of Analysis should be reviewed for peptide identity, HPLC purity, measured quantity, molecular-mass confirmation, batch number and analysis date. Mass spectrometry, HPLC purity and total vial quantity represent different analytical measurements. Confirmation of the expected molecular mass does not by itself establish purity or confirm that the vial contains the stated quantity. Storage Store the unopened vial according to the conditions stated on the product label and its batch-specific documentation. Keep the material sealed and protected from light, heat and moisture. Do not assume that storage instructions published for another supplier or pharmaceutical formulation apply to this product. For laboratory research only. Not for human consumption or veterinary use.
