This confirms the ambiguity of "pt" and "131" and highlights "peptide" as the core subject.
Dominant Search Intent: The dominant search intent appears to be related to PT-141 (Bremelanotide), a peptide used for sexual enhancement, given the strong alignment with related searches. However, the inclusion of "131" in the search keyword and the presence of other interpretations (MTP-131, Iodine-131 labeled peptides) indicates a need to address this ambiguity. The article should prioritize PT-141 but acknowledge other potential meanings of "pt 131 peptide" to some extent.

The numerical "131" in "PT 131 peptide" can also refer to different scientific entities, leading to distinct research areas:
MTP-131 (Elamipretide):
Elamipretide, identified as MTP-131, is a novel mitochondria-targeting peptide. Research has explored its therapeutic potential in various conditions, including reducing infarct size in cases of myocardial infarction and neurodegenerative diseases. Unlike PT-141, MTP-131's focus is on cellular energy production and protection, rather than sexual function.PT 141 Ditembak di St. Louis, MO
Iodine-131 (¹³¹I) Labeled Peptides:
In nuclear medicine and research, peptides are sometimes labeled with radioactive isotopes like Iodine-131 (¹³¹I).
