**1. Understanding Peptide Injections**

Peptides are typically administered subcutaneously (SQ), meaning they are injected just beneath the skin into the fatty tissue. Some peptides may also be administered intramuscularly (IM) depending on their intended effects.

**Common Injection Sites for Subcutaneous (SQ) Injections:**

• **Upper Arm:** At least 3 inches (7.5 cm) below the shoulder and 3 inches (7.5 cm) above the elbow.
  • **Outer Thigh:** On the lateral (outer) side of the thigh, avoiding bony areas.
  • **Abdomen:** Below the ribs and above the hip bones, ensuring at least 2 inches (5 cm) away from the belly button.
  Tip: Select an area where you can pinch 1 to 2 inches (2.5 to 5 cm) of skin to ensure proper subcutaneous administration.

**2. Preparation Before Injection**

**Gather Supplies:**

• Alcohol swabs
  • Sterile insulin or 1mL syringes (typically 29-31 gauge, ½-inch needle)
  • Peptide vial (reconstituted with bacteriostatic water)
  • Sharps container for needle disposal

**Wash Hands & Clean the Injection Site:**

• Wash hands thoroughly with soap and warm water.
  • Clean the injection site with an alcohol swab and allow it to air dry.

**3. Drawing Up the Peptide**

1. **Reconstitute Peptides (If Necessary):** Most peptides are supplied in lyophilized (powder) form and must be reconstituted with bacteriostatic water before use.
   2. **Mix Gently:** Do not shake the vial. Instead, roll it gently between your fingers until the powder dissolves completely.
   3. **Withdraw the Correct Dose:** Use a sterile syringe to draw the prescribed dose of peptide, hold the syringe upright, and tap gently to remove any air bubbles before administering.

**4. Performing the Injection**

**Subcutaneous Injection Steps:**

1. Pinch 1-2 inches of skin at the chosen injection site.
   2. Hold the syringe at a 45-degree angle to the skin.
   3. Insert the needle quickly and smoothly into the skin.
   4. Slowly press the plunger to inject the peptide.
   5. Withdraw the needle at the same angle and dispose of it in a sharps container.
   6. Apply gentle pressure to the site with a clean cotton pad if necessary.

**5. Post-Injection Care & Best Practices**

• Do not rub the injection site after administering, as this may cause irritation.
  • Monitor for redness, swelling, or irritation. Mild discomfort is normal, but excessive redness or pain may indicate improper technique or sensitivity.
  • Store peptides as directed—some require refrigeration while others remain stable at room temperature.
  • Rotate injection sites to avoid irritation, scar tissue buildup, or bruising.
  • Never reuse needles; always dispose of them properly.

**6. Frequently Asked Questions (FAQs)**

**How Often Should I Rotate Injection Sites?**

To prevent tissue damage or irritation, rotate sites each injection (e.g., alternate between the abdomen, thigh, and upper arm).

**Can I Inject Peptides Intramuscularly (IM)?**

Some peptides may be administered intramuscularly (IM) depending on their intended effects. This requires a 90-degree injection angle into a large muscle (e.g., glute, thigh, or deltoid).

**What Happens If I Inject in the Wrong Spot?**

If the injection was misplaced but still subcutaneous, it will likely still be absorbed. If injected into muscle unintentionally, absorption may be faster, but it is generally not harmful.

**Can I Reuse Syringes?**

No. Always use a new, sterile syringe for each injection to avoid contamination and infection.

Most Common Side Effects of Semaglutide

• Nausea: A queasy or unsettled feeling in the stomach, especially when starting treatment.

• Diarrhea: Frequent loose or watery stools, often temporary as the body adjusts.

• Vomiting: Occasional forceful expulsion of stomach contents, often linked with nausea.

• Constipation: Difficulty passing stools, leading to discomfort or bloating.

• Decreased Appetite: Reduced hunger, which can support weight management goals.
