Insulin syringe
A small-volume syringe (typically 0.3mL, 0.5mL, or 1mL) with a fixed fine-gauge needle, originally designed for insulin but widely used for subcutaneous peptide injections. Marked in units (100 units = 1 mL).

Related Terms
A 1 mL syringe with fine graduations (0.01 mL increments), used for precise measurement of small volumes. Unlike insulin syringes, tuberculin syringes often have a removable Luer lock needle.
Syringe unitsMeasurement markings on insulin syringes, where 100 units = 1 mL. Understanding syringe units is essential for accurate peptide dosing after reconstitution.
Gauge (needle)A measurement of needle diameter — higher gauge numbers indicate thinner needles. Subcutaneous peptide injections typically use 27–31 gauge needles. Thinner needles reduce pain but draw liquid more slowly.
Subcutaneous injectionAn injection into the fatty tissue layer between the skin and muscle. The most common administration route for peptides, typically using insulin syringes. Preferred for its slow, steady absorption and ease of self-administration.
