Hydration
What 0.5 oz/lb of bodyweight actually buys you.
Why it matters
Cognition
As little as 1-2% dehydration measurably degrades focus, mood, and short-term memory.
Performance
Strength output drops sharply once you cross 2% bodyweight loss. Hydrate before, not after, the session.
Peptide + GLP-1 support
GLP-1 users see fewer GI side effects with steady electrolytes; BPC-157 absorption improves with adequate plasma volume.
The longer story
Dehydration is one of the cheapest mistakes you can make. It tanks performance, slows recovery, dulls cognition, and amplifies the side effect profile of almost every peptide and supplement on the menu.
The 0.5 oz/lb rule is a starting point, not gospel. Hot climate, heavy training, GLP-1 use, sauna sessions all push the number higher. Salt and electrolytes matter as much as raw water volume.
