Sterile technique for peptide injections

CDC injection safety guidance comes down to a few habits that hold at home too:

• A new needle and syringe for every injection.
• Never put a used needle back into a vial.
• Never share a vial, needle or syringe.
• Treat multi-dose vials with care: the preservative in bacteriostatic water does not fully protect against contamination, so clean technique is still the main defense.

Clear a dry, clean surface away from food and pets. Wash your hands with soap and water; MedlinePlus says at least a minute before an injection. Lay out the vial, a sealed syringe, two alcohol swabs and a sharps container.

Confirm the label and the date you mixed it. Look for cloudiness, particles or a color change, and do not use it if you see any.

Wipe the rubber stopper with a fresh alcohol swab and let it dry. Do not touch it again or blow on it.

Open a new syringe. Pull air to your dose, inject the air into the vial, turn it upside down and draw a little past your line. Tap out bubbles and push back to the exact mark. Do not let the needle touch anything but the stopper.

How to read the lines: How to read an insulin syringe.

Common subcutaneous sites are the belly (at least 2 inches from the navel), the outer upper thighs and the back of the upper arms. Place each new shot at least an inch from the last one.

Wipe the skin with a fresh alcohol swab, starting where you will inject and circling outward. Let it air dry completely before injecting; wet alcohol stings.

1. Pinch up about an inch of skin and fat.
2. Insert the needle quickly at 90 degrees, or 45 degrees if there is little fat.
3. Release the pinch, push the plunger steadily, and withdraw the needle.
4. Press lightly with gauze or a cotton ball if it bleeds. Do not rub.

Letting a cold vial warm up first makes the shot more comfortable, according to injection guides.

Put the used syringe straight into a sharps container. Never reuse it, even on yourself. MedlinePlus also says to throw away any syringe whose cap or wrapping is broken or missing.

Injecting the same spot over and over causes lipohypertrophy: rubbery lumps of fatty tissue that absorb medication unevenly. In a study of 430 insulin users, about two-thirds had them, and only 5% of people who rotated correctly did. Reusing needles more than five times raised the risk.

A simple system: work around the belly like a clock face, keep each shot an inch from the last, then switch to the thighs or arms.

Some soreness, a small bruise or a pinprick of blood is normal. MedlinePlus lists signs of infection to call a doctor about: redness, swelling, red streaks spreading from the site, or fever. Chills, shaking or vomiting soon after a shot can point to contamination such as endotoxin, which is what FDA described after some NAD+ injections; get medical help.
