Research Overview

Arenicin-1

Marine annelid peptide with strong preclinical antibacterial activity and a stable structural motif that is useful for peptide engineering.

Ibutamoren

Clinical studies show oral ibutamoren reliably elevates GH and IGF-1 over 24 hours with once-daily dosing. Body composition and appetite effects vary by population, and development has been limited by metabolic side effects.
