An educational, source-based comparison of Macimorelin (Macrilen) and Triptorelin (Trelstar) — how each peptide works, what it's researched for, and what to know before going deeper.
Oral ghrelin agonist for diagnosing adult growth hormone deficiency.
Oral ghrelin receptor (GHSR-1a) agonist that stimulates pituitary GH release; peak GH response is measured to evaluate adult GH deficiency.
- Diagnostic test for adult GH deficiency
- • FDA-approved.
- • Avoid with QT-prolonging drugs.
- • Hold strong CYP3A4 inducers prior to test.
Decapeptide GnRH agonist that initially stimulates then desensitizes pituitary GnRH receptors, suppressing LH, FSH, and downstream gonadal steroid production after the initial flare.
- Advanced prostate cancer
- Central precocious puberty (international)
- Endometriosis (international)
- • FDA-approved.
- • Initial testosterone flare; consider antiandrogen pretreatment.
- • Hot flashes, bone density loss with chronic use.
