Glow vs KLOW — blends make attribution basically impossible and I think that's the main point
Glow is generally GHK-Cu / BPC-157 / TB-500. KLOW adds KPV to that.
So the difference is one component. But the more interesting thing to me is the structural problem with blends generally.
If someone reports anything from a four-component blend, that observation cannot be attributed to any single component. It also can't be attributed to the combination specifically, because you'd need the components separately as comparators to establish that.
Which means blend reports are, evidentially, close to uninterpretable. They're not worthless as a starting point for a question, but they can't support a conclusion about ingredients.
This seems obvious written down and yet blends are discussed as if they were single compounds constantly.
Am I being too harsh? There's presumably an argument for blends that isn't just convenience.
