Compounded Injectable Sermorelin
Sleep like you did at 28.
Recover like it too.
A once-nightly peptide that supports your body's natural growth hormone release. Members choose it for sleep, recovery, energy, and lean muscle — the things that quietly slip after 30.*
Deeper, more restorative sleep
Supports lean-muscle and recovery goals
No synthetic HGH shutdown
You did not get lazy. Your growth hormone got quiet
Growth hormone runs your body's overnight repair shift — muscle, fat, tissue, deep sleep. Output falls ~15% a decade after 30, so by 60 you make about half of what you did at 30. That's the soreness, the stubborn last pounds, the sleep that no longer restores. Sermorelin restarts the signal instead of overriding it.

Benefits that build over time
A simple look at how Sermorelin works with your body from the first signal onward.
Signals the pituitary
Sermorelin binds GHRH receptors, signaling your pituitary to release growth hormone in natural nighttime pulses.
Repair runs overnight
Higher GH and IGF-1 during deep sleep support tissue repair, protein synthesis, and fat mobilization while you rest.
You feel it downstream
Better sleep compounds into steadier energy, shorter recovery, and easier lean-muscle gains — in that order, over weeks.
Sleep first. Then everything downstream of sleep
Sermorelin builds. Here is the arc members and clinicians describe most often.
Deeper slow-wave sleep
Fewer 3 a.m. wake-ups
Mornings feel less like a fight
Week 1–2
Sleep gets deeper before anything else changes
Sermorelin's GH pulse is strongest during slow-wave sleep, so the first shift members report is the night itself: falling asleep faster, waking up less, and actually feeling rested.*
Week 3–4
Month 2–3
Month 4–6
Injected HGH floods the system and tells your pituitary to stand down. Sermorelin works one step upstream, which is why it is the option clinicians reach for first.

Losing weight is not the same as losing fat
Sermorelin works the other side of that equation: it supports overnight repair and protein synthesis, so more of the loss comes from fat and more of the muscle stays. Switch between the two to see what changes.

30 lbs kept offself-reported
Mia
I was already doing a lot of the things I thought I was supposed to do, but I couldn’t tell which ones were actually helping. Once I started noticing patterns between meals, movement and how I felt later, it became much easier to adjust without overthinking everything.
I thought I needed to exercise harder. For me, being more consistent with short walks has been much easier to keep up.
I’m not thinking about food all day anymore. I know which meals keep me satisfied and I mostly stick with those.
22 lbs kept offself-reported
Lexi
My afternoons used to be a write-off. I’d get sleepy, grab coffee and usually end up snacking. I eventually realized breakfast was setting me up for it. Changing that one thing made my whole workday feel different.
26 lbs kept offself-reported
Taylor
Before, if I felt tired or unusually hungry, I’d just assume I had no willpower that day. Now there’s usually some context. Sleep was short, lunch was tiny, I barely moved, whatever it was. Having an explanation makes the next choice feel much less emotional.
The funny thing is, nothing about my routine looks dramatic from the outside. It just works a lot better now.

It works with your own endocrine system
Mayo Clinic describes sermorelin as a synthetic version of a naturally occurring substance that stimulates the release of growth hormone from the pituitary gland.
That is the distinction from HGH: sermorelin prompts your own gland instead of introducing an external hormone, which is why it is used under physician supervision to address age-related growth hormone decline.

What is compounded sermorelin?
Sermorelin is a peptide that mimics your body's natural growth hormone-releasing hormone (GHRH). Instead of introducing external hormones, it binds to specific receptors in the pituitary gland to stimulate the natural production and secretion of your own human growth hormone (HGH). Healthy HGH levels play a key role in supporting metabolism, preserving lean muscle mass, and promoting overnight recovery. When prescribed in compounded form, sermorelin is prepared by licensed specialty pharmacies using pharmaceutical-grade ingredients.
Can I take sermorelin alongside a GLP-1?
Yes. While GLP-1 medications are effective for weight loss, losing weight rapidly can lead to a loss of lean muscle mass. Sermorelin is often used alongside these treatments because it supports natural growth hormone signaling, an important factor in preserving muscle and supporting overnight recovery while your body is in active weight loss.
How is this different from HGH?
Unlike direct HGH therapy, which involves injecting synthetic hormones that can override your system and suppress your body's own natural production, sermorelin works with your body. It signals the pituitary gland to release HGH in a more natural, pulsed rhythm, encouraging your body to replenish its own growth hormone safely and gradually.
