Sterile technique
Also called Aseptic technique, Clean technique, No-touch technique
The set of habits that keep germs out of a vial, syringe and injection site: clean hands, swabbed stoppers and skin, new needles, and never touching anything that should stay sterile.
In more detail
CDC injection safety guidance boils down to a few rules: a new needle and syringe every time, never re-entering a vial with a used needle, and treating multi-dose vials carefully because the preservative does not fully protect against contamination.
At home that means: wash hands, swab the vial stopper and let it dry, use a fresh syringe for every draw, do not touch the needle or stopper, and keep mixed vials in the fridge.
Why it matters
Most injection problems people post about, such as red, hot or swollen sites, trace back to technique rather than the peptide. Full checklist: Sterile technique for peptide injections.
Related terms
- Alcohol swabA single-use pad soaked in isopropyl alcohol, used to wipe a vial stopper or the skin before a shot.
- Bacteriostatic waterSterile water with a small amount of benzyl alcohol added as a preservative, so a vial can be punctured more than once. It is the default liquid for mixing multi-dose peptide vials.
- DrawPulling liquid from a vial into a syringe. To draw a dose is to measure the number of units you need on the syringe.
- Injection site rotationMoving each shot to a new spot, and cycling across areas like the belly, thighs and arms, so no one patch of skin takes repeated injections.
- EndotoxinFragments of bacterial cell walls that can cause fever, chills and flu-like reactions when injected. Sterilizing a product does not remove them, so they are tested for separately.
