Triptorelin (Trelstar) vs Vosoritide (Voxzogo)

An educational, source-based comparison of Triptorelin (Trelstar) and Vosoritide (Voxzogo) — how each peptide works, what it's researched for, and what to know before going deeper.

GnRH Agonist · Oncology
Triptorelin (Trelstar)

GnRH agonist depot for advanced prostate cancer.

Mechanism

Decapeptide GnRH agonist that initially stimulates then desensitizes pituitary GnRH receptors, suppressing LH, FSH, and downstream gonadal steroid production after the initial flare.

Research areas
  • Advanced prostate cancer
  • Central precocious puberty (international)
  • Endometriosis (international)
Considerations
  • FDA-approved.
  • Initial testosterone flare; consider antiandrogen pretreatment.
  • Hot flashes, bone density loss with chronic use.

CNP Analog · Skeletal Growth
Vosoritide (Voxzogo)

C-type natriuretic peptide analog for achondroplasia.

Mechanism

Modified C-type natriuretic peptide (CNP) analog that binds NPR-B, antagonizing overactive FGFR3 signaling in the growth plate to increase endochondral bone growth in children with achondroplasia.

Research areas
  • Achondroplasia in children ≥5 years (now ≥4 months)
Considerations
  • FDA-approved.
  • Transient blood pressure decrease; ensure adequate hydration/food before dosing.
