What is the difference between BPC-157 and KPV?

They come from different source molecules — BPC-157 from a gastric-juice protein and KPV from alpha-MSH — and are different sizes. Both are research-use-only reference peptides studied in gut/inflammation models.

Which is cheaper per mg?

Compare the scanned cost per milligram below; vial sizes differ, so $/mg is the fair comparison.
