most likely. i think for bis that would be easily, triceps are harder to hit properly though. if you got long ass bis with little peak id consider injecting them on the regular ...from what i hear both biceps and triceps are just fucked up to inject though... i mean ive probably hit gaps between muscle, joints, sinews, bursa sac etc in the delts too which felt fucked up for a week etc. but i think both bis and tris are full of nerves and veins, can bruise easily and you can squash nerves too... also arms are flexed ALL THE TIME in everyday life while you can pretty much avoid that with your delts if something goes wrong.
yeah, true SEO protocols call for up to 3-4mls every day for weeks... you could get benefits with smaller injects (and work up to more) but id say under 3ml or so very regularly dont even bother
