Human Growth Hormone (HGH), or somatropin, is a synthetic form of the naturally occurring growth hormone produced by the pituitary gland. It plays a vital role in cell growth, regeneration, metabolism, and muscle development. For individuals with growth hormone deficiency or for those undergoing hormone replacement therapy, somatropin is typically administered via subcutaneous injection using a convenient and precise delivery device the multi-dose injection pen.
Among the most trusted and high-quality HGH pen devices available on the market is the BIOTROPE® Somatropin Multi-Dose Pen. This article provides a comprehensive guide on how to use the BIOTROPE® pen, including preparation, injection technique, and post-use care — ensuring your somatropin therapy is both safe and effective.
What is BIOTROPE® Somatropin?
BIOTROPE® Somatropin is a recombinant form of human growth hormone (rhGH) designed for subcutaneous injection. It is commonly prescribed for:
- Adult growth hormone deficiency

Packaged in a BIOTROPE® Somatropin multi-dose injection pen, BIOTROPE® combines high-quality somatropin with an advanced pen design that ensures accurate dosing, minimal pain, and ease of use, even for patients self-administering at home.
Understanding the BIOTROPE® Pen: Key Components
Before you begin, it’s important to familiarize yourself with the components of the BIOTROPE® multi-dose pen:
- Pen Injector: Reusable, ergonomic device that houses the medication cartridge.
- Cartridge: Preloaded with somatropin solution (typically 10 mg/1.5 mL or 12 mg/1.8 mL depending on dosage form).
- Dose Selector Dial: Allows you to set your prescribed dose.
- Disposable Pen Needles: Sterile and designed for single-use.
- Protective Cap: Covers the needle after injection.
Always read the instruction manual provided with your pen and consult your healthcare provider before use.
Step-by-Step Guide: How to Use Somatropin Injection Pen
Here’s how to safely prepare and administer your BIOTROPE® somatropin injection:
Step 1: Wash Your Hands
Hygiene is critical. Wash your hands thoroughly with soap and water to prevent contamination.
Step 2: Prepare the Pen
- Attach the cartridge (if not preloaded).
- Inspect the cartridge:
- The solution should be clear and colorless.
- Do not use it if the solution is cloudy or contains particles.
- Attach a new needle securely onto the pen.
Step 3: Prime the Pen (First-Time Use)
Priming removes air bubbles from the cartridge and needle.
- Turn the dose selector to 2 units.
- Hold the pen upright with the needle pointing up.
- Tap the pen gently to move bubbles to the top.
- Press the injection button until a drop appears at the needle tip.
Repeat if no drop appears. Do not inject without proper priming.
Step 4: Set the Prescribed Dose
- Turn the dose selector dial to match the dose prescribed by your doctor (e.g., 0.5 mg, 1 mg, etc.). Always double-check before injecting.
Step 5: Choose Injection Site
Somatropin is administered subcutaneously, which means under the skin (not into the muscle). Recommended injection sites include:
- Abdomen (avoid 2-inch radius around the navel)
- Thighs (front or outer area)
- Upper outer arms (if administered by someone else)
Rotate injection sites with each dose to prevent skin irritation or lipoatrophy.
Step 6: Inject the Dose
- Clean the injection site with an alcohol swab.
- Pinch the skin lightly to create a fold.
- Insert the needle at a 90° angle (or 45° if you’re very lean).
- Press the injection button fully and hold it for at least 5–10 seconds to ensure complete delivery.
- Remove the needle and dispose of it immediately in a sharps container.
Do not reuse needles, and never share your pen device with others.
Step 7: Post-Injection Care
- Apply gentle pressure with a sterile gauze or alcohol pad if there is bleeding.
- Store the pen in the refrigerator (2–8°C), but do not freeze.
- Keep track of doses used to monitor when a cartridge needs replacement.
Safety Tips: How to Inject HGH Pen Safely
- Never inject into bruised, red, or inflamed skin.
- Keep your BIOTROPE® pen out of reach of children.
- Do not use the pen past the expiration date.
- Consult your healthcare provider immediately if you experience side effects such as joint pain, swelling, numbness, or signs of allergic reaction.
