What Sermorelin is
Sermorelin is a GHRH analogue. The first 29 amino acids of growth hormone releasing hormone, the shortest fragment retaining full activity at the GHRH receptor.
Class and mechanism

Where it sits
Growth hormone itself and the secretagogues that prompt its release are different things. Somatropin is the hormone. A secretagogue acts on the GHRH or ghrelin receptor to raise the body's own output.
Other names
Sermorelin is also written as GRF 1-29. The same molecule appears under more than one name, which is worth knowing when comparing listings between suppliers.
