Muscle + GH Axis

This category covers the growth-hormone axis, from the signal that triggers GH release to the pathways downstream of it. Tesamorelin is studied as a GHRH analogue, acting on the release-hormone side of the axis. Ipamorelin is studied as a selective GH secretagogue at the ghrelin receptor. Together they let researchers examine somatotroph function and GH pulsatility from two different directions.The compounds here are grouped by where they act on the axis, not by any effect in a person.To see the mechanism behind each, read the Tesamorelin and Ipamorelin summaries in the Research Library.Where an independent laboratory report exists for a compound, the measurements are published on the COA page, including the compounds we hold no report for.For research use only.
