It should take about 4 weeks for the blood concentraion levels to have built up enough
for you to notice anything.
For your second question, no. EQ will not totally shut down your test production, the way
other roids do (like deca, dbol, test, tren, etc), which is why I made the switch from deca to
eq for my upcoming cycle. If you're stacking your eq with anything else, the other roid may
shut down your test production, so research it first.
good luck
