Quickstart Highlights

Sermorelin is a GHRH analog — a synthetic copy of GHRH(1–29), the active fragment of growth-hormone-releasing hormone — that stimulates the pituitary to release the body’s own growth hormone (and, in turn, IGF-1)[1][6]. This educational page outlines a once-daily subcutaneous approach dosed in micrograms at bedtime, with a dilution chosen so doses land on easy-to-read insulin-syringe marks. Sermorelin was once FDA-approved (brand Geref) for childhood GH deficiency, but that product was discontinued around 2008 and no FDA-approved sermorelin exists today; adult uses are off-label/compounded or research-only and are not proven by rigorous trials — presented for research and educational use only.

Add 3.0 mL bacteriostatic water to one 5 mg vial → ~1.67 mg/mL (1,667 mcg/mL), the largest practical dilution for accurate microgram dosing.
100–500 mcg once daily at bedtime, titrated upward gradually toward ~500 mcg over an 8-week course.
At ~1.67 mg/mL, 1 unit ≈ 16.7 mcg; 200 mcg ≈ 12 units and 500 mcg ≈ 30 units on a U-100 syringe.
Lyophilized: refrigerate at 2–8 °C (35.6–46.4 °F); once reconstituted, keep refrigerated at 2–8 °C, use within 10–14 days and do not freeze the solution.

Dosing & Reconstitution Guide

A single practical dilution with accurate once-daily bedtime dosing, step by step

Standard / Gradual Approach (3 mL = ~1.67 mg/mL)

Phase / Week(s)	Nightly Dose	Volume (U-100 units / mL)
Weeks 1–2	200 mcg (1× nightly)	~12 units (0.12 mL)
Weeks 3–4	300 mcg (1× nightly)	~18 units (0.18 mL)
Weeks 5–6	400 mcg (1× nightly)	~24 units (0.24 mL)
Weeks 7–8	500 mcg (1× nightly)	~30 units (0.30 mL)

Reconstitute: Add 3.0 mL bacteriostatic water to one 5 mg vial → final concentration ~1.67 mg/mL (1,667 mcg/mL).
Typical nightly range: 100–500 mcg once daily at bedtime, raised gradually over an 8-week course.
Easy measuring: At ~1.67 mg/mL, 1 unit ≈ 16.7 mcg on a U-100 syringe. The 3.0 mL dilution keeps most doses near 12–30 units for good measuring accuracy.
Storage: Lyophilized: refrigerate at 2–8 °C (35.6–46.4 °F); after reconstitution, keep refrigerated at 2–8 °C, use within 10–14 days and do not freeze the mixed solution.
Frequency: one subcutaneous injection each night at bedtime, titrating up by about 100 mcg every 1–2 weeks toward ~500 mcg as tolerated. Bedtime dosing is strongly preferred because endogenous GH secretion peaks during sleep, so the analog reinforces the natural nocturnal pulse[3]. To start lower, 100 mcg ≈ 6 units (0.06 mL). These figures come from reference protocols, not from approved adult human dosing.

Reconstitution Steps

Draw 3.0 mL of bacteriostatic water into a sterile syringe.

Release it slowly down the vial’s inner wall to limit foaming.
Swirl or roll gently until fully dissolved — don’t shake.
Label with the date and concentration, then refrigerate at 2–8 °C (35.6–46.4 °F), shielded from light.
The 3.0 mL dilution is deliberately large so each microgram dose reads at a comfortable number of units, where U-100 syringe markings are most precise. Avoid freezing the reconstituted solution, since freeze–thaw can denature the peptide.

Protocol Overview

A concise summary of the once-daily nightly regimen, drawn from commonly cited reference protocols.

▪Goal: Stimulate the body’s own pulsatile pituitary GH release to support physiologic IGF-1 levels — effects on adult body composition are modest and not established by rigorous trials[1][2].
▪Schedule: Daily subcutaneous injections at bedtime for 3–6 months in adult research use (pediatric GHD trials ran 6–12 months)[1].
▪Dose Range: 100–500 mcg nightly with gradual titration (adult research range; pediatric GHD used ~30 mcg/kg nightly)[2].
▪Reconstitution: 3.0 mL bacteriostatic water per 5 mg vial gives ~1.67 mg/mL for accurate unit measurements.
▪Storage: Keep the dry vial refrigerated at 2–8 °C (35.6–46.4 °F); once mixed, refrigerate, use within 10–14 days and do not freeze the solution.

Dosing Protocol

A suggested nightly titration approach for adult off-label research use.

▪Start: Begin at 100–200 mcg once nightly at bedtime to gauge tolerability.
▪Titrate: Increase by roughly 100 mcg every 1–2 weeks as tolerated.
▪Target: Reach about 300–500 mcg nightly by weeks 5–8, adjusting based on IGF-1 response.
▪Cycle Length: Typically 3–6 months for adult research use; pediatric GHD trials ran 6–12 months.
▪Timing: Inject at bedtime to leverage the natural nocturnal GH pulse, and rotate injection sites systematically.

Storage Instructions

Correct storage is what preserves the peptide’s stability and activity.

▪Lyophilized: Store the dry vial at 2–8 °C (35.6–46.4 °F) in dry, dark conditions; do not freeze the dry powder and check the expiration date[2].
▪Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F) and use within about 10–14 days; do not freeze the mixed solution, as freezing can denature peptides[4].
▪Handling: Let the vial reach room temperature before reconstituting to aid dissolution, and inspect the solution before each use — it should be clear and colorless.
▪Aseptic technique: Swab the stopper with alcohol before each draw and use a new sterile needle and syringe per injection.

Important Notes

Practical points that keep daily administration safe and consistent.

▪Bedtime dosing is key: Sermorelin reinforces the natural nocturnal GH pulse, so administering before sleep is strongly recommended[3].
▪Site rotation: Move between abdomen, thighs and upper arms to reduce local irritation and lipohypertrophy[7].
▪Monitoring: Check IGF-1 at baseline and periodically (every 1–2 months) to confirm response, and assess thyroid function with long-term use, since subclinical hypothyroidism can blunt the GH response[5].
▪Recordkeeping: Log the nightly dose, time, injection site and any observations to keep the protocol consistent.
▪Regulatory note: The former FDA-approved sermorelin (Geref) was discontinued around 2008; there is no FDA-approved sermorelin today, and adult anti-aging use is off-label/compounded or research-only[2].

How This Works

Sermorelin is a GHRH analog — synthetic GHRH(1–29), the shortest active fragment of growth-hormone-releasing hormone. It binds and agonizes GHRH receptors on pituitary somatotropes, prompting the gland to release the body’s own growth hormone in natural pulses[1][6].

Unlike recombinant HGH, which replaces growth hormone directly, sermorelin works upstream and preserves normal somatostatin and IGF-1 negative feedback — the pituitary can still throttle output, which lowers the risk of supraphysiologic GH or IGF-1 levels[6]. Because it acts on the gland, sermorelin requires a functional pituitary and will not work where there is pituitary damage or a primary GH gene defect.
Its plasma half-life is short — about ~12 minutes — but the GH pulse it triggers lasts roughly 2–4 hours. That is why it is given once nightly: a bedtime dose reinforces the body’s natural nocturnal GH surge, and the resulting GH then drives hepatic and peripheral IGF-1 production[3].
Approval & evidence: Sermorelin was FDA-approved (brand Geref) for diagnosing and treating growth hormone deficiency in children, where nightly subcutaneous therapy improved height velocity over 6–12 months[1]. That product was discontinued around 2008 for commercial reasons, and there is no FDA-approved sermorelin today. Modern adult anti-aging, body-composition and sleep uses are off-label/compounded or research-only, extrapolated from pediatric and physiologic data and not proven by rigorous adult trials[2].
Sermorelin is presented here as an unapproved research chemical for research and educational purposes only.

Lifestyle Factors

Habits that may support the GH/IGF-1 response alongside the protocol.

▪Sleep quality: Prioritize 7–9 hours of uninterrupted sleep to maximize the natural nocturnal GH pulse the protocol relies on.
▪Nutrition: Keep protein intake adequate (about 1.6–2.2 g/kg/day); avoid large high-carbohydrate meals right before bedtime, which can blunt GH release.
▪Exercise: Combine resistance training with moderate aerobic activity to support the GH/IGF-1 effects on body composition.
▪Stress & substances: Manage stress (elevated cortisol suppresses GH) and limit alcohol and smoking, both of which can blunt the response.

Potential Benefits & Side Effects

Observations come mainly from pediatric trials and adult off-label research; adult efficacy evidence is limited and individual results vary.

▪Endogenous GH/IGF-1: Stimulates the body’s own pulsatile GH release, supporting physiologic IGF-1 elevation[1][2].
▪Pediatric GHD (approved use): Significant improvements in height velocity over 6–12 months of nightly therapy[1].
▪Adults (off-label): May support modest changes in body composition, energy and recovery — evidence is limited, and effects are smaller than direct GH therapy[6].
▪Preserved feedback: Built-in negative feedback reduces the risk of supraphysiologic GH/IGF-1 versus exogenous GH[6].
▪Injection-site reactions: Transient redness, pain or swelling (~17% in trials); rotating sites helps[5].
▪Rare systemic effects (<1%): Headache, flushing, dizziness, hyperactivity, drowsiness or hives[5].
▪Thyroid considerations: Subclinical hypothyroidism (~6.5% in one study) can blunt the GH response — monitor with long-term use[5].
▪Unknown long-term profile: Adult human safety data are limited, so caution and monitoring are advised.

Injection Technique

General subcutaneous technique, following established clinical best-practice guidance[7][8].

▪Wash your hands well with soap and water.
▪Wipe the vial stopper with an alcohol swab and let it air-dry.
▪Choose a site (abdomen at least 2 inches from the navel, outer thigh, or upper arm) and clean it with a fresh alcohol swab, letting it dry fully[7].
▪Draw the intended nightly dose, then check for air bubbles and push any out.
▪Pinch a skinfold at the chosen site between thumb and forefinger.
▪Insert the needle into the pinch at a 45–90-degree angle (use 45 degrees if the fat layer is thin)[8].
▪Skip aspiration for subcutaneous shots — it isn’t needed[8].
▪Press the plunger slowly and steadily until it’s fully down.
▪Wait 1–2 seconds, then pull the needle straight out to prevent leakage.
▪Apply gentle pressure with a cotton ball or alcohol pad — do not rub the site.
▪Drop the used syringe straight into a puncture-proof sharps container — never recap a needle.
▪Return the reconstituted vial to the fridge right away.
▪Rotate the injection site each day to prevent irritation and lipohypertrophy[7].
