no i have not had blood work to prove this but i do get my bloods done before after and sometimes during,the active life of enanthate is around 14 days,i personally think that by inj twice weekly it stops the blood levels dropping off which will mean no spiking of your blood levels.
i think that by splitting your dose up twice weekly can only be benificial to the user,most of the time if you are using 2 or more compounds it has to be split anyhows!
im sure someone else will chime in with a more scientific answer.
