Best Place to Inject Semaglutide (Ozempic/Wegovy): Complete Guide
Wondering where to inject your semaglutide (Ozempic or Wegovy)? I've been using semaglutide for weight loss and learned through trial and error which injection sites work best. Here's everything you need to know about where to inject, proper technique, and tips to minimize discomfort.
Quick Answer
The best place to inject semaglutide is your abdomen (stomach area), at least 2 inches away from your belly button. The abdomen has consistent subcutaneous fat, allows for easy self-injection, and typically produces the most consistent absorption. Rotate between the left and right sides of your abdomen to prevent tissue buildup.
Other approved sites include your thigh and upper arm, but the abdomen is most commonly recommended by healthcare providers for optimal results.
Approved Injection Sites for Semaglutide
Semaglutide (whether branded as Ozempic or Wegovy) is a subcutaneous injection, meaning it goes into the fatty tissue just under your skin—not into muscle. The FDA-approved injection sites are:
1. Abdomen (Stomach)
Inject at least 2 inches away from your belly button, in the fatty area on either side of your stomach.
Pros:
- Largest fatty area for most people
- Easy to reach and see
- Consistent absorption
- Typically least painful
Cons:
- Can be sensitive if too close to belly button
- Need to avoid waistband area
2. Thigh
Inject into the front or outer part of your thigh, in the middle third between your knee and hip.
Pros:
- Easy to reach
- Good fatty tissue area
- Private/discreet location
Cons:
- Can be more painful for some
- More muscle movement may affect absorption
- Less fatty tissue for lean individuals
3. Upper Arm
Inject into the back of your upper arm, in the fatty area halfway between shoulder and elbow.
Pros:
- Out of sight
- May be preferred by some
Cons:
- Difficult to reach without help
- Hard to pinch fatty tissue
- Less fatty tissue than abdomen
- More challenging for self-injection
My Personal Experience: What Works Best
I've tried all three injection sites over the past year, and here's what I've learned:
Abdomen: My Go-To Choice (90% of the time)
I inject into my abdomen about 9 out of 10 times because it's simply the easiest and most consistent. I alternate between the left and right sides, staying at least 2-3 inches away from my belly button. The injection is quick, nearly painless, and I've never had any issues with absorption or bruising.
Pro tip: I found the area slightly to the side (between your belly button and hip) tends to have the most fatty tissue and feels the least sensitive.
Thigh: Good Backup Option
When I want to give my abdomen a break, I use my outer thigh. It works well, but I personally find it slightly more uncomfortable than the abdomen. The key is using the outer/front part of the thigh, not the inner thigh, and staying in the middle third of your thigh.
Some people prefer the thigh and have no issues—it really comes down to personal preference and your body composition.
Upper Arm: Skip It (For Self-Injection)
I've only used the upper arm a handful of times, and honestly, it's too difficult to do solo. Unless you have someone to help you inject, or you're very flexible, stick with the abdomen or thigh. The upper arm is technically approved, but it's just not practical for most people doing self-injections.
Step-by-Step Injection Technique
Here's exactly how to inject semaglutide safely and correctly:
- Wash your hands thoroughly with soap and water for at least 20 seconds.
- Prepare your injection pen or syringe according to your medication's instructions. If using a pre-filled pen (like Ozempic or Wegovy pens), attach a new needle.
- Choose your injection site and clean it with an alcohol wipe. Let it dry completely (about 30 seconds).
- Pinch the fatty tissue at your injection site between your thumb and forefinger. You should have about 1-2 inches of fatty tissue lifted away from the muscle underneath.
- Insert the needle at a 90-degree angle (straight in) into the pinched skin. Push the needle in all the way.
- Inject the medication by pressing the button on your pen or pushing the plunger on your syringe. Hold for 5-10 seconds after injection to ensure all medication is delivered.
- Remove the needle straight out and release the pinched skin. Do not rub the injection site.
- Dispose of the needle in a sharps container immediately. Never reuse needles.
Important Tips for Better Injections
Rotate Your Injection Sites
Never inject in the exact same spot twice in a row. Rotating sites prevents lipohypertrophy (fatty lumps under the skin) and ensures consistent absorption. I alternate between left and right abdomen each week, and occasionally use my thigh.
Let the Medication Reach Room Temperature
Cold medication stings more. I take my semaglutide pen out of the fridge about 30 minutes before injecting. It makes a noticeable difference in comfort.
Inject at the Same Time Each Week
Semaglutide is a once-weekly injection. Pick a consistent day and time (I do Sunday mornings) to maintain steady medication levels and make it part of your routine.
Don't Inject Into Scar Tissue or Moles
Avoid areas with scars, moles, bruises, or skin that's irritated. These areas can affect absorption and may be more painful.
Relax and Go Slow
Tense muscles make injections more uncomfortable. Take a deep breath, relax your abdomen or thigh, and insert the needle smoothly. Hesitating makes it worse.
Common Injection Site Questions
Does injection site affect how well semaglutide works?
No. All three approved sites (abdomen, thigh, upper arm) deliver semaglutide into subcutaneous fat, where it's absorbed into your bloodstream at similar rates. The medication works the same regardless of which approved site you use. However, consistency matters—try to use the same general area (like abdomen) most of the time for predictable absorption.
Can I inject semaglutide in my buttocks?
No. The buttocks is not an FDA-approved injection site for semaglutide. Stick to the approved sites: abdomen, thigh, or upper arm. Using unapproved sites may affect absorption and is not recommended by healthcare providers.
What if I see blood or bruising after injection?
A tiny bit of blood or minor bruising is normal and nothing to worry about. You may have nicked a small capillary. Apply gentle pressure with a clean cotton ball if there's bleeding, but don't rub. The bruise will fade in a few days. If you're getting frequent bruising, make sure you're rotating sites properly.
How far apart should injection sites be?
Keep injection sites at least 1-2 inches apart from your last injection. For the abdomen, I simply alternate left and right sides each week, which naturally provides plenty of spacing. Don't inject in the exact same spot more than once a month.
What if I don't have much belly fat?
Even lean individuals usually have enough subcutaneous fat in the abdomen for semaglutide injections. You only need about 1-2 inches of pinchable tissue. If you're very lean and concerned, the outer thigh is typically your next best option. Talk to your healthcare provider if you're having difficulty finding appropriate injection sites.
Can I inject through clothing?
No, never inject through clothing. You need to expose the skin, clean it with alcohol, and let it dry before injecting. Injecting through fabric increases infection risk and prevents proper site preparation.

Final Thoughts
The best place to inject semaglutide is whichever FDA-approved site works best for you—but for most people, that's the abdomen. It's easy to access, has plenty of fatty tissue, and delivers consistent results.
The most important things are:
- Use proper technique (clean site, pinch fatty tissue, 90-degree angle)
- Rotate injection sites to prevent tissue buildup
- Inject at the same day/time each week
- Use a new needle every time
- Don't skip doses
Your body will tell you what feels right. Start with the abdomen since it's easiest, and if you need variety, rotate in the outer thigh. You'll develop your own routine that works for you.
