Comparison
Sermorelin vs HGH: what is the difference?
Reviewed by the FaroRx clinical team · Updated September 2026
The short answer
HGH is synthetic growth hormone injected directly, overriding your body's own control system. Sermorelin is a growth-hormone-releasing hormone analogue: it prompts your pituitary to produce more of its own growth hormone, so release stays pulsatile and self-limiting. That makes sermorelin gentler, legal to prescribe for a wider range of patients, and far less expensive — FaroRx sermorelin starts at $169 per month.
The core difference
| Sermorelin | HGH | |
|---|---|---|
| What it is | Stimulates your own GH release | Synthetic growth hormone |
| Release pattern | Natural pulses, self-limiting | Continuous, overrides feedback |
| Risk of overshoot | Low — feedback loop intact | Higher |
| Prescribing | Widely prescribable | Tightly restricted indications |
| Cost | From $169/mo at FaroRx | Often $1,000+/mo |
What sermorelin realistically does
- Deeper sleep is usually the first change, within 2–4 weeks.
- Recovery between training sessions improves by month two.
- Body composition shifts gradually over months three to six.
- It is not a shortcut to muscle without training and protein.

Is sermorelin safer than HGH?

How long before sermorelin works?
Sleep quality often improves in 2–4 weeks; body composition changes take three to six months.
Is sermorelin legal?
