I only inject glutes. The upper outer hip glute is one of the safest spots to jab. Never had the Need to jab delts or bíceps or triceps... Some people even inj chest, lats, calves haha whats the fucking point are u mad lol. Unneccessary.
I agree with this. ANd I use a 25 guage which insures that the injection won't be too fast.
