Cosyntropin (Cortrosyn) vs Triptorelin (Trelstar)
An educational, source-based comparison of Cosyntropin (Cortrosyn) and Triptorelin (Trelstar) — how each peptide works, what it's researched for, and what to know before going deeper.
Synthetic peptide containing the first 24 amino acids of ACTH — retains full corticotropic activity. Stimulates adrenal cortisol release for diagnostic testing.
- Primary and secondary adrenal insufficiency diagnosis
- • FDA-approved.
- • Single diagnostic dose; very well tolerated.
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.
