short answer= no, its not too much
long answer=
i think it depends on the person
some people respond tremendous to high volume
some not so much
also, it depends on what you have been doing, and if thats working
even for guys who do well with high volume, after a while you can stagnate and you need to switch it up
and also, are you natural bodyuilding? natural bodybuilders need to find a good balance of growth stimulation and hormonal stimulation in order to realize that growth. too much sets= adverse effects on hormones. too few sets= no growth stimulation. BALANCE
if your assisted, then all you worry about is maximizing your growth signals. so, to a point, more = better. because you hormonal level will be able to recooperate and recover from just about any amount of sets and growth stimulation.
