Do site injections benefit the muscle injected moreso than just injecting into the largest muscles? For example... If I want my bi's to grow more would it benefit more to inject into them eater than continue with glutes and thighs?
Theoretic evidence would say no.. Anecdotal evidence would say yes.
Anecdotal being personal opinion.
Basically falls under the to each his own category. Sometimes yeah, sometimes no. No harm in it, if it works it's a bonus right!
