For a newspaper piece, this one's surprisingly solid. It doesn't push any fear-based angle, like risky grey peptides or losing muscle. Instead, it covers the wide array of intriguing ways GLP's affect the nervous system and other areas, though right now that's mostly seen in animal studies, not people.
As for the research claiming brain alterations from GLP treatment, it seems nowhere near definitive. The sample was tiny, just adolescents, and their brains could be shifting because of growing older or dropping weight, not the medication.
Researchers are still looking hard into whether GLP's might slow down or stop Parkinson's.
