Research Overview
L-692,429
L-692,429 was important in early GH secretagogue research because it showed that nonpeptide molecules could trigger robust GH release. It remains a classic tool compound for studying receptor-mediated GH pulsatility and appetite signaling.
Macimorelin
Macimorelin has been validated in clinical testing as an oral alternative to injectable GH stimulation tests. Its short-term use makes it a useful translational tool for evaluating pituitary GH reserve.
