ok so i’ve been down a rabbit hole on creatine timing after someone in a peptide thread mentioned it offhand. from what i can find, the blood half-life is around 3 hours. that’s pretty short. but the muscle benefits clearly persist beyond any single dose - everyone seems to agree on that. i think i get why: it’s not abt circulating creatine, it’s abt phosphocreatine stores in the tissue, which take days or weeks to fully saturate. blood is just the delivery system, not the thing doing the work. what i’m less clear on is the secondary claims - cognitive stuff, recovery, that kinda thing. if those benefits depend on active creatine in circulation rather than tissue stores, then timing would actually matter a lot and the 3-hour window becomes relevant. but if they also work through a saturation model (some papers i found suggest creatine does cross the blood-brain barrier and accumulates in neural tissue), then the same logic applies and daily dosing builds the pool regardless of when you take it. is the blood half-life basically a red herring for everything except acute dosing experiments? feels like the saturation model is the whole answer but i can’t tell if that applies equally to the non-muscle mechanisms or just the strength/power stuff. actually curious if anyone’s seen data on brain tissue creatine levels with different dosing frequencies, not just timing of a single dose.
