and here is some more, interesting things out there to read up on

"There are recombinant ESAs with prolonged survival in circulation (‘biobetter’). First darbepoetin alfa (Aranesp®; Amgen) has come, a hyperglycosylated analog (37.1 kDa) of rhEpo, which contains two additional N-glycans in association with an exchange of five amino acids [7]. Compared with the terminal half-life of IV administered epoetin (6–9 h), the half-life of darbepoetin alfa is three- to fourfold longer (25 h), which allows for less frequent application [39]. Another bio-better is methoxy polyethylene glycol-epoetin beta (methoxy PEG-epoetin beta; Mircera®, F. Hoffmann-LaRoche). The half-life of methoxy PEG-epoetin beta (60 kDa) amounts to 130–140 h on IV injection. The prolonged in vivo survival of darbepoetin alfa and methoxy PEG-epoetin beta is in part due to a reduced EpoR binding affinity. 1 μg of darbepoetin alfa or of methoxy PEG-epoetin beta peptide corresponds biophysically to 200 IU rhEpo peptide. Clinically, however, the long-acting products may allow for dose reductions below the predicted 1: 200 ratio"

so basic run of the mill EPO has a 6-9 hr glow
more advanced is 25hrs, and that bad*ss CERA has a 130-140hrs, thats almost 6 DAYS...so what have we learned boys and girls?

well run of the mill EPO is almost IMPOSSIBLE to piss dirty on. and kiprop was warned "a few days in advance" says he must have been on something like CERA for that long of a glow time.
