How to inject
Reading your syringe
Doses on this site are written in units. A standard U-100 insulin syringe holds 100 units (1 mL). Each small line is 1 unit; each long numbered line is 10 units. Draw to the line where the black plunger tip stops.
Subcutaneous injection sites
Most peptides are injected subcutaneously — into the fat just under the skin. Common sites are the abdomen (avoid 2 inches around the navel), front outer thigh, outer upper arm, upper outer hip, or lower back. Clean the area, rotate sites, and use a new needle each time.
