Brief Description

Full-length 44-amino acid GHRH analog with a trans-3-hexenoic acid modification that improves stability and receptor binding. One of the most extensively studied GHRH analogs in published literature, with research focused on visceral adipose tissue, lipodystrophy models, IGF-1 axis modulation, and cognitive function in aging populations. For research use only — not for human consumption.
