Sermorelin Dosage in 2026: What Clinicians Actually Prescribe

Quick Answer

The short version: Sermorelin is dosed via subcutaneous injection, typically once daily, typically at bedtime. When prescribed off-label by anti-aging clinics, doses are typically in the 100-300 mcg range nightly.

Sermorelin at a glance:

  • Drug class: GHRH analog
  • FDA approved: 1990
  • Route: subcutaneous injection
  • Typical frequency: once daily, typically at bedtime
  • Half-life: approximately 11-12 minutes

The wrong Sermorelin dose — too high, too low, or escalated too quickly — is the most common reason people stop the drug. When prescribed off-label by anti-aging clinics, doses are typically in the 100-300 mcg range nightly.

Standard Dosing Schedule for Sermorelin

When prescribed off-label by anti-aging clinics, doses are typically in the 100-300 mcg range nightly.

The typical schedule for Sermorelin is once daily, typically at bedtime via subcutaneous injection. Half-life of approximately 11-12 minutes explains why this schedule works — the drug stays active long enough to support that interval.

Titration: Why Starting Low Matters

For this class of compound, gradual titration is the standard approach. The starting doses listed above are not therapeutic — they exist to let the body adapt and to reduce gastrointestinal symptoms .

A typical titration plan for Sermorelin holds each dose step for at least four weeks before moving up. Faster titration is associated with more dropouts due to side effects.

Missed Doses

If a dose of Sermorelin is missed: for daily schedules, the rule of thumb is to take it as soon as remembered if within a defined window, otherwise skip it and resume the regular schedule. The exact window depends on the half-life (approximately 11-12 minutes) and the specific product label. Never double up to make up for a missed dose.

Dose Adjustments

Dose adjustments may be needed for the following:

  • Significant weight loss or weight gain
  • Side-effect intolerance at the current step
  • Changes in renal or hepatic function
  • Drug interactions (particularly relevant for any concurrent medications)

We cover the side-effect side of dose decisions in Sermorelin side effects and the cost angle of dose escalation in Sermorelin cost.

What the Trials Used

Published trial data for Sermorelin comes primarily from: Pediatric GHD studies forming basis of historical FDA approval.

That data drives the labeled dosing range, which is what physicians prescribe by.

Special Populations

The dosing guidance above applies to general adult use. Special populations — pregnancy, pediatric, severe renal impairment, hepatic dysfunction, elderly with frailty — require individualized assessment that this page can't substitute for.

For Sermorelin: the standard contraindications for this drug class apply.

Bottom Line

Most Sermorelin dose questions resolve in a 5-minute conversation with a clinician. Don't carry them around — get them answered.
