GHRH stimulates the somatotroph directly; arginine suppresses hypothalamic somatostatin, removing the brake. Together they test the pituitary itself rather than the hypothalamus, which is what a deficiency diagnosis needs, and the peak is high enough that normal and deficient separate cleanly. Obesity blunts the response, so cut-offs were stratified by body mass index.
It missed deficiency of hypothalamic origin, as after cranial irradiation, because a direct pituitary stimulus bypasses the lesion.
Without a pharmaceutical GHRH the test could not be run. The glucagon test, older and less specific, returned to use. Macimorelin, acting on the ghrelin receptor, gave an oral test validated against the insulin tolerance test. The episode is a case study in how a diagnostic depends on the commercial survival of a reagent.
Tesamorelin was developed for a therapeutic indication and its label does not include diagnostic use.
Because the diagnostic history explains how the pituitary reserve that tesamorelin depends on is measured, and because a GHRH analogue sits in the catalogue. It describes clinical history and no use of the pack.
Tesamorelin is supplied by REVIVE LAB UAE for laboratory research use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
