Step-by-step injection process Step 1: Clean injection site Choose site (abdomen or thigh) Clean area with alcohol wipe Circular motion, outward from center Let alcohol dry completely (30-60 seconds) Don't touch cleaned area Step 2: Pinch skin Use thumb and forefinger Gently pinch up fold of skin (1-2 inches) Creates subcutaneous pocket Lifts fat away from muscle Hold pinch throughout injection Step 3: Insert needle Hold syringe like a dart Insert at 45-90 degree angle (subcutaneous) Quick, confident motion (less painful) Insert needle completely (usually 1/2 inch) Should feel minimal resistance Step 4: Inject PT-141 Slowly push plunger down Inject over 5-10 seconds Smooth, steady pressure Complete full dose Don't rush (prevents stinging) Step 5: Remove and dispose Pull needle straight out Release pinched skin Light pressure with clean tissue if needed Dispose needle in sharps container Don't recap needle (injury risk) Post-injection: Massage injection site gently (helps absorption) Wash hands Note time of injection (for timing) Track dose and response Injection troubleshooting: Timing PT-141 for optimal results When to dose for best effects
