# Sermorelin Reconstitution and Dosing: GHRH 1-29 in the Literature
> Note: PeptIQ is not a medical provider. This article is educational only. It is not a protocol.
Sermorelin is a synthetic analog of the first 29 amino acids of human growth hormone-releasing hormone. Older endocrine writing treated GHRH fragments as diagnostic and therapeutic tools for GH stimulation (Grossman, Savage, and Besser, PubMed 2429796). ClinicalTrials.gov still indexes sermorelin studies (search).
The analog is short-acting relative to albumin-binding GHRH constructs such as CJC-1295 with DAC. That half-life difference is why community pages talk about nightly or multi-daily administration. Frequency talk is a pharmacokinetic story, not a verified consumer schedule.
Evidence tier
| Layer | Strength | Limit |
|---|
| Classic GHRH / sermorelin endocrine papers | Mechanism and GH-stimulation context | Decades-old clinical frames, not 2026 obesity-drug style RCTs |
| Compounding-clinic education | How U.S. wellness practice often discusses micrograms | Practice variation, not FDA labeling for anti-aging |
| Community and in-app logs | What people record at night | Observational |
Sermorelin has been used as a branded diagnostic agent in some historical markets. That history does not make an unlabeled research vial equivalent to a pharmacy-prepared product.
Lyophilized-vial math
Educational write-ups use:
Concentration (mcg/mL) = (vial mg × 1,000) ÷ diluent mL
Volume (mL) = desired mcg ÷ concentration
Illustrative example only
A vial labeled 5 mg with 2 mL bacteriostatic water is 2,500 mcg/mL. A 200 mcg discussion figure would be 0.08 mL (8 units on a U-100 syringe). A 300 mcg figure would be 0.12 mL (12 units). PeptIQ's reconstitution helper uses a 5 mg / 2 mL / 200 mcg example row for sermorelin as a calculator default. That is a math preset, not a prescribed dose.
Bacteriostatic water is the diluent named most often for multi-draw vials. Secretagogues are often described as pH- and mix-sensitive. Separate vials remain the conservative educational default when another peptide is in the same protocol discussion. Refrigeration after reconstitution is the usual storage claim.
Research-reference ranges
Clinic-facing pages commonly discuss nightly subcutaneous microgram amounts in the low hundreds, sometimes titrated against IGF-1 and symptoms. Those pages reflect compounding and wellness-clinic culture. They are not a modern labeled indication for "optimization."
Published GHRH work used study-specific stimulation tests and treatment courses. Extrapolating a 200 mcg nightly habit from a 1980s endocrine paper is a category error.
| Source | Figure people cite | Reading |
|---|
| Historical GHRH papers | Stimulation-test and treatment exposures | Study context |
| Compounding education | ~200–300 mcg, often evening | Practice culture |
| In-app logs | Evening entries, sometimes paired with a GHRP | Observational |
PeptIQ users who log sermorelin often treat it as a nightly GH-axis entry rather than a weekly metabolic drug. That cadence matches the short-analog story. It does not prove benefit.
Route language
Subcutaneous administration is the route named in clinic education and community write-ups. Evening timing is a narrative about sleep-associated GH pulses. It is not an instruction to inject. Technique stays with a clinician or a labeled product's instructions for use.

Bottom line
Sermorelin is a short GHRH analog with a real, older endocrine literature. Reconstitution math is generic. Nightly microgram charts are clinic and forum culture. They are not a contemporary labeled protocol.
