About this group
Compounds in this group are studied for their action on the somatotropic axis: releasing hormones, ghrelin-receptor secretagogues, downstream growth factors and the upstream reproductive signalling that interacts with them. They are often referred to collectively as HGH peptides, which is convenient shorthand but a slightly misleading one — none of them is human growth hormone. They act on the axis that regulates it, which is a different class of molecule and the reason they are studied separately from HGH itself. Compounds in this group are also what searches for peptides for muscle growth and muscle building peptides tend to land on. Those phrases describe a hoped-for outcome in a person rather than anything that can be said about research-grade material, and we do not make that claim: this is laboratory material studied on the somatotropic axis in research models, not supplied for human use. Several are commonly researched in combination, which is why blends appear here as well as single compounds.
