Sermorelin (Overnight Rebound): What It Is & Common Questions

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 medical intake to determine whether treatment is appropriate. If your provider does not approve treatment, your refund is the amount you paid minus the non-refundable consultation fee.
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? Follow the storage instructions and printed use-by or beyond-use dates on the label and in the package from the pharmacy that dispensed your medication.
For medical questions about storage, temperature exposure, or how long your medication can be used, log in to your Member Portal and ask your doctor. You can also message support for general information or help locating the pharmacy instructions. Support staff are not medical professionals and can only provide general information, not personalized medical advice or confirmation that a medication is safe to use.
How do I cancel? Billing depends on the purchase option you selected. CoreAge Rx offers one-time purchases and optional subscriptions; review the options shown for your order. A one-time purchase does not renew automatically. If you selected a subscription, you can cancel it at any time to stop future renewals by using the cancellation option in your Member Portal, if your account shows one, or by contacting support@coreagerx.com. Your cancellation must be received before the next renewal is processed. Tell support if you also want to cancel a current order. All sales are final once your prescription has been approved and sent to the pharmacy. Your order cannot be cancelled after both steps are complete, even if it has not shipped yet. Canceling a subscription stops future automatic renewals only. It does not automatically cancel or refund an order that has already been processed, and it does not refund medication that has already been approved, sent to the pharmacy, compounded, dispensed, or shipped, or any order that has otherwise become non-refundable. See Pricing & Plans for the difference between the purchase options.
