Recovery · Sermorelin
Your body still knows how to make growth hormone. Sermorelin is the signal that tells it to. A clinician-prescribed injection that acts on your pituitary gland the way your own growth hormone-releasing hormone (GHRH) does. 100% online, prescribed only when clinically appropriate by a US-licensed clinician.

Growth hormone is your body's repair signal. It's released in pulses, most of it during deep sleep, and it tells your tissues to build muscle protein and burn stored fat for fuel. In healthy men, output falls about 14% with every decade of adult life. Here's the part most people never hear: the gland that makes it usually still works. What fades is the signal from the brain telling it to fire. Sermorelin is a synthetic copy of the active part of that signal, growth hormone-releasing hormone (GHRH). It isn't growth hormone. It prompts your pituitary to release its own, in pulses, with your body's feedback loops still in charge. Pallas connects you with US-licensed clinicians who prescribe compounded sermorelin when it's clinically appropriate for you, as a subcutaneous injection with dosing personalized to your health history. One plan price covers your clinician, ongoing check-ins, care-team messaging, and your medication when prescribed, shipped free and discreet from a US-licensed pharmacy.
Sermorelin is a synthetic copy of the first 29 amino acids of growth hormone-releasing hormone (GHRH), the signal your brain sends to your pituitary gland. It prompts the pituitary to release your body's own growth hormone, the hormone that drives muscle repair and fat metabolism and that declines steadily through adult life. At Pallas it's prescribed as a compounded subcutaneous injection, only when a US-licensed clinician determines it's clinically appropriate for you.
Sermorelin is prescribed to support your body's own growth hormone release. In small clinical studies of adults with age-related growth hormone decline, GHRH(1-29) and a close analog raised overnight growth hormone and IGF-1, and some participants saw gains in lean mass, some strength measures, skin thickness, insulin sensitivity, and general well-being. Sleep quality did not change in the longest of those trials. The studies were small and short, results vary from person to person, and a US-licensed clinician decides whether sermorelin is appropriate for you.
No. Sermorelin is not growth hormone and is not an HGH replacement. It works upstream, prompting the pituitary gland to release its own growth hormone in pulses, with the body's feedback loops still regulating how much is released. Whether it's appropriate for you is a clinical decision made by a US-licensed clinician.
One price with provider care included, and nothing is charged at checkout. Compounded sermorelin is $139 for your first month, then $199 every 4 weeks, charged once a clinician prescribes, and renews until you cancel. Longer plans lower the average ($139/mo on the annual plan), and a month-to-month plan is available at checkout. If a clinician decides treatment isn't right for you, you're refunded in full.

What is sermorelin
Growth hormone is your body's repair signal. It's released in pulses, and in men about 70% of the day's output comes in the first hours of deep sleep.2 It tells your tissues to build muscle protein and burn stored fat for fuel.1 In healthy men, output falls about 14% with every decade of adult life.3 Here's what most people never hear: the pituitary gland that makes it usually still works. What fades is the signal from the brain telling it to fire.6 Sermorelin is that signal, a synthetic copy of the first 29 amino acids of growth hormone-releasing hormone (GHRH), the part your pituitary actually reads.4
The research
Growth hormone drives the protein synthesis that rebuilds muscle after you train.1 In studies of older men, GHRH(1‑29) and a close analog raised growth hormone, with gains in lean mass and some strength measures.6,7,8
In men, deep sleep and growth hormone fall together between early adulthood and midlife.9 Sermorelin is not a sleep aid. It's prescribed to support the growth hormone pulse that window is built around.

Yes — sermorelin can be prescribed through telehealth in the US when a US-licensed clinician determines it's clinically appropriate for you, and it's prepared by state-licensed US compounding pharmacies. As with any prescription, whether it's suitable depends on your health history — that's why every Pallas plan starts with a clinician review, and certain conditions mean sermorelin isn't an appropriate treatment.

The most commonly reported are brief facial flushing and redness, soreness, or swelling at the injection site. Headache, dizziness, and nausea are reported less often. Tell your clinician about every medication you take, since thyroid medication and glucocorticoids can affect how sermorelin works. Stop and seek medical care right away for signs of an allergic reaction, such as hives, swelling of the face or throat, or trouble breathing.
That's a clinical decision. A US-licensed clinician reviews your health history and goals and determines whether sermorelin is appropriate for you — it isn't right for everyone. Per our clinical partner's prescribing criteria, the program is available to adults 55 and under, and certain conditions (including pregnancy or breastfeeding, active cancer, pituitary disease, untreated hypothyroidism, uncontrolled diabetes, and heart failure) mean it isn't an appropriate treatment.
No. Compounded sermorelin is prepared per-patient by state-licensed US compounding pharmacies and is not FDA-approved. That's exactly why every plan starts with a US-licensed clinician who reviews your health history and prescribes it only when clinically appropriate.

Compounded sermorelin is not FDA-approved. The studies below describe growth hormone physiology and small, short trials of GHRH(1-29) and a close analog, mostly in adults over 55. They are not evidence that compounded sermorelin will produce any specific result for you. Sermorelin is prescribed only when clinically appropriate by a US-licensed clinician, and individual results vary.
