Hard to say with certainty since human data is missing for KPV and thin for BPC. GLP-1 medications stand out as the stronger anti-inflammatory option worth prioritizing. Still, BPC gets frequent mentions for pets and people alike and appears very safe in studies with no established toxic dose, so trying it seems reasonable.
At 34 I'm dealing with ongoing pain from several disc bulges, nerve compression in the neck and lower back, plus arthritis in multiple joints. Started KPV recently and am considering whether adding BPC-157 on its own or together would be worthwhile.
