Step by step
- Clean the site. Wipe the skin with an alcohol swab and let it dry.
- Pinch and insert. Pinch a fold of skin and insert the needle at 45 to 90 degrees into the fat layer.
- Inject slowly. Push the plunger down steadily, then withdraw and apply light pressure.
- Rotate and dispose. Note the spot so the next injection moves over, and drop the needle in a sharps container.
Where to inject
- Abdomen — about two inches out from the navel
- Love handles / flank
- Upper outer thigh
- Back of the upper arm
How to rotate
- Move about an inch from your last injection each time
- Do not use the exact same spot two days running
- Avoid scar tissue, bruises, and any lump or hardness

FAQ
Most peptides are given subcutaneously, into the fat under the skin, with a short insulin needle. Follow your provider's direction for anything meant to go intramuscular.
For most subcutaneous peptides the site makes little difference to the effect. Rotation matters more — it keeps the tissue healthy.
Injecting the same spot repeatedly can cause lumps, irritation, and poor absorption. Rotating avoids that.
