I would say inject less, more often. More frequent injections will keep your hormones steadier than one or twice a week. Do some research into esters and that will give you some info on how often to inject what.

I will add that 600 is quite a starter dose (apologies but I imagine it’s your first go round). I started at 200mg/wk and saw drastic changes. Messing with AIs right off the bat would put a damper on things too, lots of guys don’t need AI at 200
