Sermorelin injectable amber vial, peptide growth hormone therapy by Immortals

“Sermorelin is a peptide that prompts your body to release its own growth hormone in natural pulses. It works through the same mechanism as tesamorelin, an FDA-approved peptide that's been shown to shrink visceral fat. Sermorelin itself has never been tested in a clinical trial so using it for weight management is experimental and off-label.”

WHY GHRH AGONISTS

Growth hormone declines with age. GHRH agonists help restart the signal.

HOW SERMORELIN WORKS

Stimulates natural growth hormone release.

Sermorelin prompts your pituitary gland to release growth hormone, supporting muscle growth, fat loss, sleep, and recovery.

Signals pituitary gland

Sermorelin acts on cells in the pituitary gland, mimicking signals your body naturally sends to release growth hormone.

Supports metabolism

Growth hormone circulates to the liver, where it stimulates IGF-1 production. They work together to support increased muscle mass, fat loss, sleep, recovery, and tissue repair.

Releases growth hormone

The pituitary releases your body's own growth hormone in its natural rhythm of pulses, the on-off pattern your body is designed to respond to.

COMMON QUESTIONS

Questions, answered

What is sermorelin?

Sermorelin is a peptide similar in structure to growth hormone-releasing hormone (GHRH). It signals the pituitary gland to release growth hormone in its natural, rhythmic pulses. 

It’s important to note that sermorelin is an experimental longevity treatment, and your doctor will likely recommend monitoring biomarker signals for safe administration.

How do you take sermorelin?

Sermorelin is typically administered at night, before bed, to align with your body's natural growth hormone pulse during deep sleep.

Inject 15 to 30 units of sermorelin into the skin each night on 5 nights of the week. Inject on an empty stomach.

What are the side effects of sermorelin?

Side effects may include injection site reactions, antibody development, joint pain, facial flushing, and nausea. 

Who shouldn’t take sermorelin?

Not recommended for people who are pregnant or breastfeeding, or people with a current or past diagnosis of cancer. Your doctor will evaluate whether sermorelin is appropriate for you.
