23gx1in. I think the problem with this delt shot was i shot test and right in the same area i shot hcg and we all know if that water and oil get together somehow this could happen. From now on before every shot i am going to heat the gear up under hot faucet
Not sure what is causing your knots but water and oil can be shot together no problem. I always use some water based b12 in my shots, never had an issue.
chances are either the gear needs to be refiltered or maybe you aren't injecting properly. Just curious, why use delts for cruising dose......glutes/ventroglute/quads would be my top choices, dont really need that many spots when only doing 2 small injections a week,
