Very sure, I've injected just about everything under the sun, and I needed large volumes of water at times.
And I've no clue what kind you had, and if you even had any. You mentioned insulin syringes, and I just wanted to make sure you didn't try making a Frankenstein rig!
Buy yeah, just try it, man, hopefully it will fit. Just test first to make sure they're is no leakage.
Put it this way: I once bought a 5ml syringe from Kroger, and then attached a 27g so I could inject 50mg liquid methadone.(10mg/ml). Worked like a charm. ?
