The 18 gauge needle works well at producing a reasonable size hole that is less likely to reseal, though multiple punctures may be necessary. The finer gauge 25 gauge can be used on thicker skin. The very fine 33 gauge needle is for blood glucose testing; I don’t often use these, but they are far easier to buy than a hypodermic. (Pharmacies are reluctant to sell hypodermics without some obvious medical justification, so I get mine online in bulk.)
