When it comes to safe and effective semaglutide therapy, details matter. At Best Shape of Me, we are proud to distribute SEMANIZE® semaglutide, one of the highest-grade formulations available today. SEMANIZE® is not only formulated with a premium active ingredient but is also designed with advanced multi-dosage injection pen technology—tailored for convenience, precision, and flexibility.
One unique feature of the SEMANIZE® semaglutide pen is that it is delivered without pre-attached or bundled insulin needles. This decision is intentional. Why? Because we believe in empowering our users with choice—to match their injection preferences and comfort levels. While we leave the final selection to you, we’re here to guide you through the process and ensure you have the information you need to make the right decision.
Understanding Needle Specifications

When choosing a needle for your SEMANIZE® pen, two key factors come into play:
- Gauge (G) – This refers to the diameter of the needle.
- Length (mm) – This determines how deep the needle penetrates the skin.
Let’s take a closer look at the four top-recommended needle options:
Gauge (G) | Length (mm) |
31G | 5mm |
31G | 8mm |
32G | 4mm |
32G | 5mm |
What Does “G” Mean?
The gauge value indicates the thickness of the needle. Counterintuitively, a higher gauge number means a thinner needle. So, a 32G is thinner than a 31G making it ideal for those concerned with injection discomfort. Fortunately, both 31G and 32G are exceptionally fine and designed for virtually pain-free use.
What Does the Length Determine?
Needle length is measured in millimeters and typically ranges between 4mm and 8mm. This determines how deep the medication is delivered into the body.
Semaglutide must be injected into the subcutaneous (SC) layer—the thin layer of tissue just beneath the skin. The goal is to avoid penetrating muscle or fatty tissues and to keep the dose confined to this delicate SC layer.
- Shorter needles (e.g., 4mm or 5mm) are often sufficient for individuals with thinner or more elastic skin.
- Longer needles (e.g., 8mm) may be preferred by those with thicker skin or for specific injection sites on the body.
Remember, the angle of injection also matters. For SEMANIZE®, we recommend an angle between 45° and 60°, depending on the injection site and skin tension. This ensures the needle reaches the subcutaneous layer without going too deep.
Choosing the Best Needle for You
Here’s how to assess your best fit:
- Are you new to injections? Try starting with a 32G 4mm needle. It’s the thinnest and shortest—ideal for beginners and those with sensitivity.
- Do you have thicker skin or more subcutaneous fat? A 31G 8mm needle may provide better delivery depth.
- Want a balance between comfort and coverage? Opt for the 31G 5mm or 32G 5mm needle.
- Have a favorite injection site? Consider how skin thickness varies across sites (e.g., thigh vs. abdomen) and match your needle length accordingly.
No matter your choice, always follow proper technique and local sterilization practices to ensure hygiene and safety.
Injection Tips for SEMANIZE® Users
To help you feel confident with every injection, each SEMANIZE® pen comes with a detailed instructional leaflet, including:
- How to attach and remove the needle correctly.
- Best practices for selecting injection sites.
- Tips for reducing pain and minimizing bruising.
- How to angle the injection to reach the subcutaneous layer.
- Signs to look for if the injection is too deep or too shallow.
We recommend reading the leaflet before your first injection and keeping it handy for quick reference.
And don’t forget: always sterilize the injection area with alcohol before use. This small step helps prevent infection and maintains optimal skin health.
