Syringe Guide:

Gauges, Barrel Sizes, and Needle Length

There are plenty of syringes to choose from when injecting intravenously. This guide will focus on the difference between gauge, needle length, barrel size, and what syringe sizes work best on different body parts.

Let’s say that the syringe above is a “27g 0.5 CC 1/2” tip”:

Needle gauge: The needle gauge refers to the size of the hole in the needle. It’s important to flag that the higher the gauge number, the smaller the opening of the needle. In this case, our needle tip is 27g, which is larger than a 30g, but smaller than a 24g needle tip. Most intravenous users will use insulin syringes, which have 28 or 27 gauge needles, when injecting into limbs. Needle tips always have a chance of clogging from blood or impurities in the drugs. The larger the gauge, the higher the chance of clogging because the opening is smaller. Needle tips will dull each time they break skin. It’s important to keep switching to an unused needle every other poke to reduce the trauma to the vein.

Barrel size: The barrel size will dictate how much liquid goes into the syringe. Syringes used intravenously will either be 1cc or 0.5cc and are calibrated by either .10cc or .05cc along the barrel of the syringe. Our syringe above is a 0.5cc which means it will pull up less substance than a 1cc barrel. A larger barrel size makes diluting your product easier. A smaller barrel size can be beneficial when shooting less liquid into the vein. Intravenous users have also claimed they’re easier to maneuver when shooting in tricky spots like the back of the arms.

Needle length: The length of needles used intravenously will usually be 1/2” or 5/16”. It’s important to choose a needle length that will reach the vein but will not puncture through the opposite vein wall. Drugs injected outside or around a vein can lead to burning sensations, especially when shooting meth or coke, and can cause abscesses, infections, and a diluted high. 1/2” syringe tips are usually used to shoot into limbs and 5/16” syringe tips are usually used for more delicate veins on hands and feet.

29 1/2” tip 1cc

27, 29 and 28 gauge needles are best used to shoot in the arms and legs. They are thick enough to properly enter and anchor into the vein and long enough to reach the veins in the limbs without piercing them. Short syringe tips will be beneficial for shooting into shallow veins in these areas.

30 and 31 gauge needles are best suited for shooting into hands and feet. This is where shallow and more delicate veins reside. The thinner needle will cause less trauma to these veins.
