Tesamorelin is a synthetic 44-amino-acid analog of human growth hormone-releasing hormone (GHRH). It features a trans-3-hexenoic acid modification on the tyrosine residue at position 1, which confers resistance to dipeptidyl peptidase-4 (DPP-4) degradation and extends its functional half-life in preclinical models. Research labs use tesamorelin to study the hypothalamic-pituitary axis, pulsatile GH secretion patterns, and downstream IGF-1 signaling cascades. It is frequently compared against ipamorelin and CJC-1295 in assay designs that seek to distinguish GHRH-receptor-mediated effects from ghrelin-receptor-mediated GH release. Our tesamorelin is synthesized to >99.6% purity and analyzed by HPLC-UV and ESI-MS. The 10 mg vial supports extended dosing protocols. Store lyophilized at −20°C; reconstitute with bacteriostatic water before use. FAQ What is tesamorelin? Tesamorelin is a synthetic GHRH analog studied in laboratory models for growth hormone secretion, IGF-1 pathway activation, and pituitary somatotroph response. Where can I buy tesamorelin for research? You can buy research-grade tesamorelin from Haelo Labs. Our 10 mg vials are third-party tested with HPLC purity verification and mass spectrometry identity confirmation. How does tesamorelin differ from CJC-1295? Tesamorelin is a GHRH analog with a trans-3-hexenoic acid modification for DPP-4 resistance. CJC-1295 (no DAC) is a 29-amino-acid GHRH fragment with different stability kinetics.
