What Is Sermorelin (Overnight Rebound)?
Overnight Rebound is a physician-prescribed Sermorelin peptide therapy. Sermorelin signals your own pituitary gland to release growth hormone — it is not synthetic HGH. Because it works with your body's natural feedback loops rather than replacing the hormone, it's used as a foundational anti-aging protocol when clinically appropriate.
Your Sermorelin is compounded acetate, personalized to your prescription, and shipped cold-packed from a 503A licensed pharmacy.
What It May Help With
- Leaner body composition
- Deeper, more restorative sleep
- Faster workout recovery
- Smoother skin and fuller hair
How You Take It
A small subcutaneous injection once a day, Monday through Friday, before bed, using the included 31G insulin syringe (typically into the abdomen or thigh). Your pituitary does the rest while you sleep. Your exact protocol is personalized by your prescribing physician.
Who It's For
- People who work hard and need better recovery
- Adults 25+ noticing declining sleep quality
- Active individuals 40+ who want to hold onto strength
- People whose body composition is slipping despite healthy habits
Who It's NOT For
- Anyone pregnant or breastfeeding
- People with an active cancer diagnosis
- People with active proliferative diabetic retinopathy
- Anyone under 25 years old
- People with severe, untreated sleep apnea
- Anyone unwilling to inject daily
Side Effects
Most common: mild flushing, warmth, or redness at the injection site that lasts a few minutes. Less common: a brief headache, lightheadedness, or tingling. Tell your clinician about anything that concerns you.
What to Expect Over Time
- Within ~2 weeks: Sleep quality often improves first
- 2–3 months: Visible body-composition changes begin to emerge
- Months 3–12: Deeper benefits continue to compound
Frequently Asked Questions
Does the injection hurt? It uses the smallest available needle (31G), so most people describe it as a brief pinch.
How is this different from synthetic HGH? Synthetic HGH replaces the hormone directly. Sermorelin instead signals your pituitary to release its own growth hormone, which preserves your body's natural feedback loops.
Do I need a prescription? Yes. Sermorelin is prescription-only. A U.S.-licensed clinician reviews your intake first, and you're only charged if you're approved.
Do I have to cycle on and off? Cycling and protocol length vary by physician based on your goals and bloodwork. Follow the plan your clinician sets and ask them through the member portal if you have questions.
Is it FDA-approved? Compounded medications are not FDA-approved. Your Sermorelin is prepared by a 503A licensed pharmacy for you specifically.
How is it shipped and stored? It ships cold-packed. Refrigerate it on arrival and follow the storage instructions on your vial label.
How do I cancel? There's no auto-billing — you order each shipment when you need it.
