Test affects sleep

Have just commenced week 2 of my Sustanon-only cycle(250mg, twice weekly). Been noticing that my quality of sleep hasn't been great at all.

I have a hunch that it might be the test affecting my sleep and my body still adapting to it (never shot test before), plus with increased training intensity/heavier weights (?)

What do you guys think?

Could be it due to other factors instead of the sustanon?

drink chamomile tea. and u may wan't to add linden tea leaves to it. try reading before u go to sleep as you drink this. no sugar.
makes me knock right out naturally too.
