Quick answer
Sermorelin is a peptide that tells your pituitary gland to release your own growth hormone, in its natural overnight pulses. It is not HGH and not a steroid. People use it for deeper sleep, faster recovery between workouts and leaner body composition over a 3 to 6 month course. It is one small shot before bed, prescribed by a licensed provider. At PepHaus it is from $143 per month.
What sermorelin is
Sermorelin is a synthetic copy of the first 29 amino acids of growth hormone releasing hormone, the signal your hypothalamus sends to your pituitary gland. That 29 amino acid fragment is the active part of the full hormone, which is why sermorelin can do the same job.
Growth hormone output peaks in your late teens and declines through adulthood. The pulses get smaller and fewer, and the biggest one, the deep sleep pulse in the first hours of the night, shrinks the most. Slower recovery, lighter sleep and a body that holds fat more easily after 30 track that decline closely.
Sermorelin was originally developed as a diagnostic and a treatment for growth hormone deficiency in children. Today it is prescribed off label by licensed providers as a compounded medication for adults, and compounded sermorelin is what PepHaus ships.
How it works
Your pituitary already knows how to make growth hormone. What fades with age is the signal. Sermorelin restores the signal.
- You inject a small dose before bed. Subcutaneous, under the skin of the belly or thigh, with an insulin size needle.
- It binds GHRH receptors on the pituitary. The pituitary responds the way it would to your own releasing hormone.
- Growth hormone is released in a pulse. Timed with deep sleep, where the largest natural pulse already happens.
- Your feedback loop stays in charge. Somatostatin and IGF-1 still regulate how much is made, so levels stay inside a physiologic range instead of being set by the dose.
That last point is the whole reason people choose sermorelin over injecting growth hormone itself. With HGH, the dose decides the level. With sermorelin, your body does.
Sermorelin vs HGH, TRT and other peptides
| Sermorelin | HGH (somatropin) | TRT (testosterone) | CJC-1295 / Ipamorelin | |
|---|---|---|---|---|
| What it is | GHRH analog, 29 amino acids | Growth hormone itself | Testosterone, a steroid hormone | GHRH analog plus a ghrelin mimetic |
| How it raises GH | Signals your pituitary to release your own | Replaces it directly | Does not act on GH | Two signals to the pituitary at once |
| Feedback loop | Intact | Bypassed | Suppresses your own testosterone | Intact |
| Main use | Sleep, recovery, body composition | Diagnosed GH deficiency | Low testosterone symptoms | Same goals as sermorelin |
| Prescription | Yes, compounded | Yes, tightly controlled | Yes | Limited, availability varies by pharmacy |
| Can be combined with TRT | Often, with provider supervision | Sometimes | n/a | Often |
Sermorelin and TRT are not competing. Testosterone therapy addresses low testosterone. Sermorelin addresses the growth hormone axis. Many people on TRT add sermorelin for sleep and recovery, and many people who do not need TRT use sermorelin on its own. Your provider confirms what fits.
Sermorelin vs CJC-1295 and ipamorelin. Those two are usually combined to hit the pituitary from two directions. Sermorelin is the single, longer studied signal with a cleaner safety history, and it is the one PepHaus providers prescribe.
Who sermorelin is for
Recovery got slower after 30
You train hard and the soreness lasts longer than it used to. You want to recover between sessions the way you did ten years ago.
Sleep is light and mornings are rough
You fall asleep fine but wake up unrefreshed. Deeper sleep is the first thing most people notice.
Body composition has drifted
Same training, same food, more fat around the middle. You want lean mass up and fat down without a steroid.
Already on TRT
Testosterone fixed some things and not others. Sleep and recovery are the gap sermorelin targets.
Healthy aging, long game
You want your own hormones working on your own rhythm, with a provider adjusting the plan.
Done with research vials
You want a prescription, a licensed pharmacy, a Certificate of Analysis and someone to message.
Men and women both use sermorelin. The biology of the growth hormone decline is the same.
What to expect, week by week
Individual results vary, and a provider will tell you the same. This is the pattern most people describe.
| When | What people commonly report |
|---|---|
| Week 1 to 2 | Deeper sleep, more vivid dreams, easier mornings. Some mild injection site redness. |
| Week 3 to 6 | Steadier daytime energy. Soreness after training clears faster. |
| Week 6 to 12 | Recovery between sessions noticeably better. Early shifts in body composition for people who train and eat well. |
| Month 3 to 6 | Lean mass and fat changes become visible. This is the window providers plan around before judging results. |
Sermorelin is not a quick fix. It restores a signal and lets your body do the work, which means the results build with consistency. Skipping nights slows everything down.
Dosing and timing
- Once nightly, before bed. The natural growth hormone pulse happens in the first deep sleep cycle, so the dose goes in right before it.
- Empty stomach is better. Insulin blunts growth hormone release. Finish eating 1 to 2 hours before the shot.
- Subcutaneous. Belly or thigh, rotating sites. Insulin size needle, barely felt.
- Your provider sets the dose. Providers start low and adjust to your response and tolerance.
- Cycles. Many providers prescribe in 8 to 12 week blocks with breaks between. Cycle length is a provider decision.
- Storage. PepHaus vials ship ready to use, no mixing. Keep refrigerated.
Specific milligram amounts are set during your provider visit. Any number you read on a forum is someone else's prescription, not yours.
Side effects and safety
Most people tolerate sermorelin well because it works through your own regulatory system. What gets reported:
- Common: injection site redness, swelling or itching, flushing, headache.
- Less common: dizziness, nausea, sleepiness right after the dose, changes in taste.
- Tell your provider about: joint swelling, numbness or tingling in the hands, anything that does not settle in a few days.
Sermorelin is not appropriate for everyone. People with an active cancer or a history of certain cancers, untreated thyroid conditions, or who are pregnant or breastfeeding are generally not candidates. A licensed provider reviews your full history before anything is prescribed, and $0 is charged until you are approved.

Frequently asked questions
What is sermorelin?
Sermorelin is a synthetic version of the first 29 amino acids of growth hormone releasing hormone (GHRH). It signals the pituitary gland to release your own growth hormone in its natural pulses, mostly during deep sleep.
Is sermorelin the same as HGH?
No. HGH is the growth hormone itself, injected directly. Sermorelin prompts your own pituitary to release growth hormone, so your body's feedback loop stays in charge of how much is made.
Is sermorelin a steroid or testosterone?
No. Sermorelin is a peptide that works on the growth hormone axis. It is not an anabolic steroid and it does not contain testosterone. Some people use it alongside testosterone therapy under provider supervision.
When do you take sermorelin?
Most providers prescribe one small subcutaneous injection at night before bed, timed to the window when the body naturally releases growth hormone during deep sleep. Your provider sets the dose.
How long does sermorelin take to work?
Changes in sleep are usually the first thing people report, often within the first few weeks. Recovery and body composition changes tend to take longer. Most providers plan for a 3 to 6 month course before judging results. Individual results vary.
What are the side effects of sermorelin?
The most common are injection site redness or itching, flushing, and headache. Less common are dizziness, nausea and sleepiness after the dose. Tell your provider about anything that does not settle.
Who should not take sermorelin?
People with an active cancer, untreated thyroid problems, or who are pregnant or breastfeeding, among others. A licensed provider reviews your history before anything is prescribed.
How much does sermorelin cost?
At PepHaus, sermorelin is from $143 per month on the 6-month plan, $151 per month quarterly, or $159 per month monthly. The provider visit, supplies and free shipping are included. Full breakdown on the sermorelin cost page.
Is compounded sermorelin FDA approved?
No. Compounded medications are prepared for individual patients by licensed pharmacies under a provider's prescription and are not FDA approved products. Every PepHaus vial ships with a Certificate of Analysis.
