My friend is currently injecting 1.5 ML eod and he wants to know if it would be ok if he split it up into two .75 ML injections instead and did something like both delts then both quads then both delts again eod. He's worried this might cause more scar tissue build up. I wasn't really sure so I told him I'd ask here? Do you guys think he needs to find more injection sites if he does this?
EDIT: His plan is actually full dose right thigh, full dose left thigh, half dose both shoulders, half dose both shoulders, repeat.
