Where to Inject GLP-1 for Best Results

Why Injection Technique Matters

GLP-1 therapies like semaglutide work by:

• Slowing gastric emptying
• Enhancing satiety signals
• Regulating insulin and glucagon secretion

Proper subcutaneous injection ensures gradual, stable absorption, which supports consistent blood levels and effects ².

Where to Inject GLP-1: Recommended Sites

1. Abdomen

• Most common and user-friendly
  
• Inject at least 2 inches from the navel
  
• Avoid scarred or bruised areas
  
• Ideal for self-administration
  
  

2. Thigh

• Use the front or outer thigh
  
• Pick a spot halfway between hip and knee
  
• Rotate between legs weekly
  
  

3. Upper Arm

• Use the back of the upper arm (between shoulder and elbow)
  
• Best done with assistance
  
• Ensure injection is into fatty tissue, not muscle
  
  

Research confirms comparable bioavailability across all these sites ¹, allowing patients to choose based on preference and accessibility.

‍

Injection Tips for Comfort and Safety

• Clean your hands and site with alcohol
  
• Pinch a skin fold to avoid intramuscular delivery
  
• Insert the needle at a 90° angle (or 45° if you’re lean)
  
• Hold the injector button until all medication is delivered
  
• Do not rub the site post-injection

How to Rotate GLP-1 Injection Sites

Rotating your injection location helps prevent:

• Skin thickening (lipohypertrophy)
• Bruising and soreness
• Absorption variability ¹

‍

‍

Sample Rotation Plan

‍

‍

Return to previous areas after at least 4 weeks to allow skin to recover ¹.

‍

What to Avoid

Do not inject into:

• Bruised, red, or scarred areas
• Muscle or veins
• Skin with stretch marks, infections, or near your navel (stay 2" away)

These locations may increase discomfort and reduce absorption reliability ¹.

Common Mistakes and Fixes

Managing Injection Site Reactions

Mild redness or swelling is common and temporary. To minimize discomfort:

• Use new needles each time
• Let alcohol dry fully before injecting
• Rotate sites to reduce irritation ¹
• Apply a cool compress if needed

If irritation persists, consult your provider.
