Sermorelin, Prescribed and Monitored by Physicians

Safety, Side Effects and What to Expect

Common Side Effects

Injection-site reactions are the most frequently reported — redness, swelling, itching, or a brief stinging sensation. These are usually mild, settle within a short time, and are often related to injection technique, rotation of sites, or injecting the solution cold.

Less common, generally mild:

• Headache
• Flushing
• Dizziness
• Nausea
• Altered taste sensation
• Drowsiness — one reason evening dosing is typical

Related to fluid retention — a recognized effect of increased growth hormone signaling:

• Mild swelling in the hands, feet or ankles
• Joint aches or stiffness
• Numbness or tingling in the hands, which can reflect carpal tunnel-type compression

Fluid-related effects are typically dose-related and often improve with adjustment. They are a reason to speak to your clinician rather than to push through.

Effects on Blood Sugar

Growth hormone reduces insulin sensitivity. The magnitude of this effect with chronic compounded sermorelin use in adults is not well quantified, which is itself the reason for monitoring rather than assumption. Anyone with diabetes, prediabetes or insulin resistance needs closer monitoring, and glucose is part of both baseline and follow-up lab work.

This is not a reason to avoid sermorelin if you have metabolic risk factors. It is a reason for it to be supervised.

Drug Interactions

A full medication review before starting is not a formality. The classes that matter:

Tell your clinician about supplements as well as prescriptions.

Who Should Not Take Sermorelin

Compounded sermorelin has no FDA-approved label, so there is no formal contraindication list to quote. What follows is the position taken by the clinicians prescribing it here.

Not a candidate for this therapy:

• Known hypersensitivity to sermorelin or its excipients, particularly a prior anaphylactic reaction
• Pregnancy, a planned near-term pregnancy, or breastfeeding
• Active malignancy — growth hormone signaling and cell proliferation are linked
• Significant hypothalamic-pituitary structural disease or an intracranial lesion
• Acute critical illness, or recent major surgery

Individual assessment rather than a blanket rule:

• Cancer in remission, including at five years — handled explicitly with your treating oncologist rather than decided in isolation
• Diabetes, prediabetes or insulin resistance, uncontrolled or untreated
• Uncontrolled or untreated thyroid disease, under- or over-active
• Significant liver or kidney disease

Competitive athletes: growth hormone secretagogues — the class sermorelin belongs to — are prohibited under World Anti-Doping Agency rules and are a disqualifier regardless of prescription. Check with your governing body before starting.

When to Contact Your Clinician

Seek emergency care (call 911) for:

• Difficulty breathing, facial or throat swelling, widespread hives — possible severe allergic reaction
• Chest pain

Contact your clinician promptly for:

• Persistent headaches, visual changes, or persistent nausea
• New or worsening joint pain, or swelling of hands, feet or ankles
• Numbness or tingling in the hands
• Symptoms of high blood sugar — increased thirst, frequent urination, blurred vision
• Fever, spreading redness, warmth or pus at an injection site
• Any new lump, unexplained weight loss, or persistent unexplained pain
