Research Overview

Somatropin

Somatropin is the best-studied growth hormone peptide, with decades of clinical use in pediatric and adult GH deficiency. Trials consistently show increases in IGF-1 and growth velocity, with adverse effects mainly reflecting excessive GH exposure.

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.
