Post-Workout Protein Calculator
The 0.25–0.40 g/kg per-sitting dose, with the anabolic-window myth given its honest size.
About 20–30 g of quality protein maximises the post-session synthesis response for most adults — more isn't harmful, just not extra-anabolic at that sitting. The 'window' is hours wide, not 30 minutes: total daily protein and per-meal distribution dominate; the post-gym shake is convenience, not chemistry deadline.
