I cannot prove that the half life of parent trenbolone is not 24 hrs.. But if it was, EOD dosing would have little difference between ED dosing, furthermore, 2xED dosing would mean nothing.. and guys swear by 2xED dosing.
Really, though, try the graphs again giving it a 24hr half life (as reported by Bill Roberts and Brock Strasser)..
If you posted those graphs, NOBODY would do EOD dosing ever again.. there would be HUGE (well over 100%) spikes in blood concnetrations.
I think that study indicates that tren in rats may have a half life of 24hrs.. However, I am certain this is not the case with humans... If it were, this would be some kind of record for a non 17AA steroid.. It would surpass the half life of any other parent AAS by about 1200%
