Pegvisomant (Somavert) vs Triptorelin (Trelstar)
An educational, source-based comparison of Pegvisomant (Somavert) and Triptorelin (Trelstar) — how each peptide works, what it's researched for, and what to know before going deeper.
Pegylated GH receptor antagonist for acromegaly.
Genetically engineered analog of human GH with site-directed mutations blocking functional dimerization of the GH receptor; pegylation extends half-life. Lowers IGF-1 without lowering GH.
- Acromegaly inadequately controlled by surgery, radiation, or somatostatin analogs
- • FDA-approved.
- • Monitor LFTs; tumor monitoring via MRI required.
- • Lipohypertrophy at injection sites.
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.
