Quickstart Highlights
GHRP-6 is a synthetic growth-hormone-releasing peptide and ghrelin (GHS-R1a) receptor agonist that triggers a short pulse of growth hormone from the pituitary; a hallmark of GHRP-6 is strong hunger and appetite stimulation[1][5]. This educational page outlines a subcutaneous approach on an empty stomach, with a dilution chosen so doses land on easy-to-read insulin-syringe marks. It is an unapproved research chemical, not a medicine, and muscle, recovery and anti-aging benefits are not established by rigorous human trials — presented for research and educational use only.
Add 3.0 mL bacteriostatic water to one 10 mg vial → ~3.33 mg/mL (3,333 mcg/mL), the largest practical dilution for accurate dosing.
100–300 mcg per dose, 1–3× daily on an empty stomach, titrated upward gradually across a 12-week course.
At ~3.33 mg/mL, 1 unit ≈ 33.3 mcg; 100 mcg ≈ 3 units and 300 mcg ≈ 9 units on a U-100 syringe.
Lyophilized: store at −20 °C (−4 °F); once reconstituted, refrigerate at 2–8 °C (35.6–46.4 °F) and do not freeze the solution.
Important: Start with the Prep & Injection Guide — it covers the preparation and safety basics every protocol on this site assumes.
Dosing & Reconstitution Guide
A single practical dilution with accurate once-daily dosing, step by step
Standard / Gradual Approach (3 mL = ~3.33 mg/mL)
Reconstitute: Add 3.0 mL bacteriostatic water to one 10 mg vial → final concentration ~3.33 mg/mL (3,333 mcg/mL).
Typical dose: 100–300 mcg per dose, 1–3× daily on an empty stomach, raised gradually over a 12-week course.
Easy measuring: At ~3.33 mg/mL, 1 unit ≈ 33.3 mcg on a U-100 syringe, so 100 mcg ≈ 3 units and 300 mcg ≈ 9 units — small, readable volumes on the U-100 scale.
Storage: Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and do not freeze the mixed solution.
Frequency: typically 1–3 subcutaneous injections per day on an empty stomach, titrating up as tolerated. The GH response is generally reported to plateau around ~100 mcg per dose, so the protocol is built around that response ceiling rather than ever-larger single doses[3][4]. These figures come from reference protocols, not from approved 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 gives ~3.33 mg/mL so each dose reads in clear, low single- and double-digit unit marks on a U-100 syringe. Avoid freezing the reconstituted solution, since freeze–thaw can denature the peptide.

Supplies Needed
Quantities below assume an 8–16 week course of once-daily injections with gradual titration.
At these microgram doses a 10 mg vial lasts well beyond a week, so only a few vials cover a full course.
- Low end (~100–200 mcg/day): ~2–3 vials
- Mid (~300–600 mcg/day): ~4–6 vials
- High (up to 900 mcg/day): ~8–10 vials
- Per injection: 1 syringe
- 12 weeks (1× daily): ~84 syringes
- 12 weeks (3× daily): ~252 syringes
Use ~3.0 mL per 10 mg vial for reconstitution.
- Low course (~3 vials): ~9 mL → 1 bottle
- High course (~10 vials): ~30 mL → 3 bottles
One for the vial stopper + one for each injection site, every dose.
- Per injection: 2 swabs
- 12 weeks (1–3× daily): ~170–500 swabs → 2–5 boxes
Protocol Overview
A concise summary of the once-daily regimen, drawn from commonly cited reference protocols.
- ▪Goal: Stimulate a short pulse of pituitary growth hormone via the ghrelin (GHS-R1a) receptor; appetite stimulation is the most consistent reported effect — broader benefits are not established in humans[5][6].
- ▪Schedule: Subcutaneous injections 1–3× daily on an empty stomach for about 12 weeks.
- ▪Dose Range: 100–300 mcg per dose with gradual titration, built around the ~100 mcg GH-response ceiling.
- ▪Reconstitution: 3.0 mL bacteriostatic water per 10 mg vial gives ~3.33 mg/mL for accurate unit measurements.
- ▪Storage: Keep the dry vial frozen at −20 °C (−4 °F); once mixed, refrigerate at 2–8 °C and do not freeze the solution.
Dosing Protocol
A suggested daily titration approach based on common reference doses.
- ▪Start: Begin at 100 mcg per dose, 1–3× daily on an empty stomach, to gauge tolerability and appetite response.
- ▪Titrate: Increase by roughly 100 mcg per dose every two weeks as tolerated.
- ▪Target: Reach about 300 mcg per dose by weeks 5–12, staying near the ~100 mcg per-dose GH-response ceiling.
- ▪Cycle Length: Typically 8–12 weeks; some references extend to ~16 weeks.
- ▪Timing: Inject at a consistent time each day and rotate injection sites systematically.
Storage Instructions
Correct storage is what preserves the peptide’s stability and activity.
- ▪Lyophilized: Hold the dry vial at −20 °C (−4 °F) in dry, dark conditions and limit moisture exposure[7].
- ▪Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F) and use within about 28 days; do not freeze the mixed solution, as freezing can denature peptides[8].
- ▪Handling: Let frozen vials warm to room temperature before opening so condensation won’t form, and keep the solution clear of heat and direct light.
- ▪Freeze–thaw: Avoid repeated freeze–thaw cycles of the reconstituted solution.
Important Notes
Practical points that keep daily administration safe and consistent.
- ▪Sterile technique: Use a fresh sterile U-100 insulin syringe each time and drop it straight into a puncture-proof sharps container afterward.
- ▪Site rotation: Move between abdomen, thighs and upper arms to reduce local irritation and lipohypertrophy[9].
- ▪Slow injection: Push the plunger slowly and pause a few seconds before withdrawing the needle to prevent backflow.
- ▪Recordkeeping: Log the daily dose, injection site and any observations to keep the protocol consistent.
- ▪Regulatory note: GHRP-6 is prohibited by WADA for athletic use and is not FDA-approved for human administration[10].
How This Works
GHRP-6 is a synthetic growth-hormone-releasing peptide — a hexapeptide that acts as an agonist at the ghrelin / GHS-R1a receptor[1][2]. Binding that receptor on the pituitary and hypothalamus drives a pulse of growth-hormone release.
Its core mechanism is GH secretagogue activity: it stimulates GH-releasing pathways while suppressing somatostatin, producing a transient rise in growth hormone. A defining feature of GHRP-6 is strong stimulation of hunger and appetite, an effect that follows directly from ghrelin-receptor activation[5][6].
Studies also report a modest rise in cortisol and prolactin alongside the GH pulse[11]. Crucially, the GH response tends to plateau near ~100 mcg per dose, so larger single doses add little extra GH while increasing side effects[12].
Important caveat: there are no completed human efficacy trials showing that GHRP-6 builds muscle, improves recovery or slows aging. Most data come from short pharmacology and animal studies of GH release. Muscle, recovery and anti-aging claims rest on the GH-pulse mechanism and anecdote, and should be read as hypotheses.
GHRP-6 is not an approved medicine. It is an unapproved research chemical presented here for research and educational purposes only.
Lifestyle Factors
Habits that may support healthy growth-hormone output alongside the protocol.
- ▪Nutrition: GHRP-6 increases appetite, so plan balanced, adequate-protein meals rather than overeating on impulse.
- ▪Activity & rest: Pair regular activity with real rest; avoid timing doses around large meals, since food blunts the GH response.
- ▪Sleep: Aim for 7–9 hours, when the largest natural growth-hormone pulses occur.
- ▪Stress: Manage stress with evidence-based practices, since cortisol can counteract growth-hormone signalling.
Potential Benefits & Side Effects
What short pharmacology and animal studies describe; human evidence is limited and individual results vary.
Potential Benefits
- ▪GH release (pharmacology): Reliably triggers a short pulse of growth hormone via the ghrelin/GHS-R1a receptor in human and animal studies[5][6].
- ▪Appetite stimulation: Strong, consistent increase in hunger — the most reliably reported effect of GHRP-6[11].
- ▪Short-term tolerability: Generally tolerated in short studies, with mild injection-site reactions reported.
- ▪Note on humans: Muscle, recovery and anti-aging benefits are not established in humans — no large-scale clinical efficacy trials of GHRP-6 have been completed[13].
Common Side Effects
- ▪Hunger & injection-site reactions: Marked appetite/hunger is expected; mild redness or soreness at the site can occur, and rotating sites helps.
- ▪Cortisol / prolactin & unknown long-term profile: A modest rise in cortisol and prolactin can occur; human long-term safety data is limited, so caution and monitoring are advised.
- ▪Sport restriction: Note that GHRP-6 is a WADA-prohibited substance for athletes.
Injection Technique
General subcutaneous technique, following established clinical best-practice guidance[14][15].
Pre-Injection Preparation
- ▪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, thigh, or upper arm) and clean it with a fresh alcohol swab, letting it dry fully[15].
- ▪Draw the intended dose, then check for air bubbles and push any out.
Injection Procedure
- ▪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)[14].
- ▪Skip aspiration for subcutaneous shots — it isn’t needed[14].
- ▪Press the plunger slowly and steadily until it’s fully down.
- ▪Wait 5–10 seconds, then pull the needle straight out to prevent leakage.
Post-Injection Care
- ▪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[9].
- ▪Watch the site for excess redness, swelling, or signs of infection.

GHRP-6 — frequently asked questions
How do I reconstitute a 10 mg vial of GHRP-6?
Wipe the stopper with an alcohol swab, then inject your bacteriostatic water slowly down the inside wall of the vial. Let it sit and gently swirl until dissolved — never shake. Store the mixed vial in the refrigerator and draw doses with an insulin syringe. Use the calculator above to turn any dose into syringe units.
How much bacteriostatic water should I add to GHRP-6?
There is no single correct amount — more water simply spreads the same 10 mg of peptide across a larger volume, which makes small doses easier to measure accurately. 1 to 3 mL per vial is typical. Enter your chosen volume in the calculator above to see the resulting concentration and syringe units.
What do the "units" on an insulin syringe mean?
On a U-100 insulin syringe, 100 units equal 1 mL, so 1 unit equals 0.01 mL. The calculator above converts your draw volume into these units automatically so you can measure without doing the math by hand.
How should I store GHRP-6 after mixing?
Keep the reconstituted vial refrigerated at roughly 2 to 8 degrees Celsius, away from light, and avoid freezing it. Reconstituted research peptides are generally used within a few weeks. Always follow the specific guidance supplied with your product.
How many doses does a 10 mg vial of GHRP-6 provide?
Divide the vial strength of 10 mg by the amount you use per injection. The calculator above reports this as "doses per vial" the moment you enter a dose.
Is GHRP-6 approved for human use?
No. GHRP-6 is sold strictly for laboratory and research purposes and is not approved by the FDA or other regulators for human use. Everything on this page is research information, not medical advice — consult a licensed healthcare professional before any use.
