SLC6A8
SLC6A8 creatine transporter — the molecular target that 1 compounds in the wiki act on.
In one line: The doorway that pulls creatine into your muscles.
SLC6A8 is the transporter that moves creatine into muscle cells, where it recharges your cells' rapid-energy "battery" for short, explosive effort. Supplementing creatine keeps this battery topped up beyond what food alone provides — giving you an extra rep or two and faster recovery between hard sets.
It's the delivery door for the most proven, cheapest performance supplement there is.
