While many patients tolerate peptides very well, it's important to understand that all medications carry the potential for side effects, and peptides are no exception. Side effects can vary depending on the specific peptide, your body’s response, and your health history.
🧬 Common Side Effects (May Occur with Any Injectable Peptide):
Mild redness or irritation at the injection site
Headache or lightheadedness
Fatigue or feeling flushed
Nausea or digestive discomfort
Temporary water retention or bloating
🔍 Peptide-Specific Considerations
1. NAD+
Tingling, cramping, or flushing during or after injection
Possible fatigue or light headache if dosed too high
2. Sermorelin
Vivid dreams or temporary sleep disruptions when starting
Tingling/numbness (rare)
Mild joint stiffness or swelling in some users
3. Glutathione
Rare allergic reactions (itchiness or rash)

🛑 When to Contact a Provider
You should reach out to your provider immediately if you experience:
Severe injection site reactions (swelling, warmth, or pain)

💬 Final Note
Most side effects are mild and temporary, especially when peptides are taken as prescribed. Always follow your provider’s instructions and report anything unusual so adjustments can be made if needed.
