arimidex and igf serum levels

I have been on growth for 2.5mos now and have also been using ISA-Test to raise test levels. Nipples are a little sore and dont know if it is from the growth or isa-test (tribbullus) not sure of spelling? I was considering taking some arimidex but heard it could adversely affect my IGF levels while on growth. Does anyone know what the story on all this is?

arimidex and nolva lower igf levels,letro and aromasin actually help raising igf levels.
i don't think its really noticeable but none the less i would go with aromasin as its not as bad for your lipid profiles as letro.
