yeah you should cut some volume... but i wouldn't neccesssarily go "low" volume
Just knock a set or two off each excercise and maybe add a day or two of rest... keep calories high as possible and make sure your getting plenty of sleep
over-training is very easy when you come
off cyclebut try and keep the weight heavy to maintain strength
EDIT:
I'd add a cortisol blocker to your PCT as well... this is a life saver since cortisol will most likely
spike within a week or so of coming off
