just do 250 iu's twice a week that's enough and more practical than ed injections.
if u shoot ur weekly test dose once a week then shoot the hcg on the 2 days b4 that, for eggs. if u shoot test on mondays then shoot 250iu hcg on saturday and another 250iu on sunday.
if u divide ur weekly test dose to twice a week then it doesn't matter do ur hcg on the same day of ur test shots.
