Mod GRF 1-29 is a modified synthetic analogue of growth hormone-releasing hormone (GRF 1-29) with amino-acid substitutions designed to improve stability, studied in GH research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Mod GRF 1-29 is investigated in research on growth hormone release and neuroendocrine regulation, and is commonly applied in cell-based and preclinical studies. The lyophilized format provides good stability and reproducible reconstitution for consistent experimental dosing. Every batch passes strict quality control, and a Certificate of Analysis is available for specific batches on request. For storage keep the unopened vial sealed at 2-8 degree C protected from light and moisture; for long-term storage store at -20 degree C and avoid repeated freeze-thaw cycles.
