is stacking three things at once ever defensible

about supplier pages as sources is a supplier page ever a source for anything here

brb, thin evidence, higher bar

for the sceptics whats a sensible way to tell whether a stack did anything at all, not urgent

GHK-Cu is the one where photos would help and nobody ever controls the lighting
