Is this you?
Train hard. Recover harder. That part gets quietly harder after 35.
You train consistently
But recovery takes longer than it used to and the muscle doesn’t come as easy.
Your sleep has shifted
You’re in bed 7–8 hours but waking up feeling like you only got 5.
Your body comp is changing
Same diet. Same gym. More fat around the middle. Less lean mass than 5 years ago.
If two of these land, your growth hormone output is almost certainly not where it was at 28.
How Sermorelin works in the body
Stimulates
growth hormone
Sermorelin signals your pituitary gland to produce more of your body's own natural growth hormone.
Promotes
muscle recovery
Higher GH levels accelerate tissue repair, helping you bounce back faster between training sessions.
Improves
sleep quality
GH pulses are tied to deep sleep — restoring them supports more restorative, energy-replenishing rest.
Why it happens
Growth hormone doesn’t disappear. It just quietly steps back.
GH production peaks in your early 20s and falls roughly 14% per decade after that. By 40, most adults have less than half the output they had at their physical peak. By 50, the effects are hard to ignore — slower recovery, shifting body composition, sleep that doesn’t feel restorative, and a ceiling on lean mass that keeps dropping.
Sermorelin doesn’t replace growth hormone. It signals your pituitary — the gland that controls GH release — to restore its own natural pulses. Your body makes more of what it already knows how to make. The result is physiologic, gradual, and measurable.

Representative of average population decline. Individual variation applies.
The protocol
Four things that change in the first 90 days.
Weeks 2–3
Sleep deepens first
GH release is tied to slow-wave sleep. Most patients notice deeper, more restorative sleep before any physical changes are visible.
IGF-1 +30–40%
The number we measure
IGF-1 is the downstream marker of GH activity. Your baseline is captured at day 0. At day 90, we measure again. The number tells you if the protocol is working.
Month 3–6
Body composition shifts
Lean mass increases. Visceral fat responds. Studies show an average of 6+ lbs lean mass gain over a 90-day protocol with consistent resistance training.
Daily
Nightly subcutaneous dose
One small injection, nightly, at the same time your body naturally pulses GH during sleep. Insulin-pen gauge needle. Takes under 60 seconds.
How it works
From intake to first dose in under a week.
01
Complete your intake
Five minutes. We review your goals, health history, and current medications. A lab order goes out the same day.
02
Clinician reviews your labs
IGF-1, testosterone, TSH, and metabolic panel. A US-licensed physician reviews your results and prescribes your protocol.
03
Compounded and shipped
Your sermorelin is compounded by a 503A US pharmacy and shipped overnight in temperature-controlled packaging. Monthly refills are automatic.

Common questions
Straight answers.
Is sermorelin the same as HGH?
No. HGH (human growth hormone) is a synthetic hormone injected directly into the body. Sermorelin is a peptide that signals your pituitary to produce its own GH — keeping your body’s natural feedback loop intact. It’s a fundamentally different mechanism with a cleaner safety profile.
How long until I see results?
Most patients notice improved sleep quality within 2–3 weeks — this is usually the first signal. Changes in energy and recovery follow at weeks 4–6. Body composition shifts — lean mass gain and fat reduction — typically become measurable at months 3–6 with consistent training.
Do I need a prescription?
Yes. Sermorelin is a prescription medication and requires a clinical evaluation. After you complete your intake, a US-licensed physician reviews your health history and lab results before prescribing. Not everyone is approved — and that’s by design.
What bloodwork do I need?
We order a baseline panel that includes IGF-1, TSH, free testosterone (or estradiol), fasting insulin, hsCRP, and a comprehensive metabolic panel. We send the requisition to Quest or Labcorp within hours of your intake, or ship a Tasso at-home kit to you. At day 90 you re-test. The numbers tell the story.
Can I stack this with NAD+ or GHK-Cu?
Yes — and many patients do. NAD+ and sermorelin target different pathways (cellular energy vs GH pulsatility) and stack without conflict. GHK-Cu topical serum is complementary for skin and recovery. Your clinician can advise on protocol combinations at your intake review.
What if it doesn’t work for me?
We measure. If your IGF-1 hasn’t moved meaningfully at day 90, your clinician reviews your protocol and adjusts — dose, timing, or combination. We don’t guess. The bloodwork tells us what to do next.
