GHRP-6 Dosage Protocol

Growth Hormone-Releasing Peptide-6 · ghrelin-receptor secretagogue

The reference protocol uses 100 mcg three times daily in weeks 1–2, 200 mcg in weeks 3–4, then 300 mcg through week 12. With 3 mL of bacteriostatic water, a 10 mg vial is 3.33 mg/mL, so 100 mcg is 3 units (0.03 mL) on a U-100 syringe.

Each listed amount is per administration; the reference schedule uses three administrations daily.

The reference site describes an empty-stomach interval and at least 4 hours between administrations.

The staged 12-week schedule uses 63 mg in total, equivalent to seven nominal 10 mg vials.

02 · HOW TO MIX

Mixing a 10 mg vial with 3 mL of BAC water

Using a 1 mL (100-unit) insulin syringe, 3 full draws of bacteriostatic water gives 3.33 mg/mL.

1
Add the water slowly
Wipe both rubber stoppers with an alcohol swab and let them dry. Draw 3 mL of bacteriostatic water and let it run slowly down the inside of the vial wall — not straight onto the powder.
2
Swirl gently
Swirl or roll the vial gently until the powder has dissolved. Give it a few minutes to settle if needed.
3
Don't shake it
Shaking can damage the peptide and cause foaming. Gentle swirling only.
4
Check it's fully clear
Only use it once it is fully clear with no particles. Label the vial with the date and 3.33 mg/mL, then store it in the fridge at 2–8 °C.

About GHRP-6

Protocol overview

Starting dose: 100 mcg per administration, three times daily
How it increases: 200 mcg in weeks 3–4, then 300 mcg in weeks 5–12
Frequency: Three times daily
Timing in source: At least 4 hours apart; the reference site describes an empty-stomach interval
Protocol length: 12 weeks in the matching reference chart
Default mix: 3 mL bacteriostatic water → 3.33 mg/mL

Storage

Before mixing: Keep the unopened lyophilised vial sealed, dry and away from light at the product-specified temperature.
After mixing: Refrigerate upright at 2–8 °C away from light; Peak says to use within about 28 days.
Never: Never freeze the reconstituted solution or use it if it is cloudy, has particles, unexpected colour, leakage or stopper damage.

How it works

GHRP-6 is a synthetic six-amino-acid growth-hormone secretagogue. It acts through the growth-hormone secretagogue receptor rather than the growth-hormone-releasing-hormone receptor, and can prompt pituitary growth-hormone release.

Human physiology research found changes in growth hormone and other hormones after GHRP-6. Those short-term hormone responses do not establish long-term effects on muscle, recovery, body composition or athletic performance.

Illustrated mechanism explainer

What the research shows

A phase I pharmacokinetic study enrolled nine healthy men who each received one intravenous bolus of 100, 200 or 400 mcg/kg; the mean elimination half-life was 2.5 ± 1.1 hours.
A diagnostic study gave 20 adults GHRP-6 at 1 mcg/kg, alone or with 1 mcg/kg GHRH. Mean peak growth hormone after GHRP-6 alone was 25.7 mcg/L in the growth-hormone-sufficient group and 1.3 mcg/L in the deficient group.
In a study of 9 younger and 9 older healthy adults, an intravenous 90 mcg GHRP-6 bolus changed growth-hormone responses; combining it with 100 mcg GHRH produced a greater response than either substance alone.
Australia's current Poisons Standard lists GHRP-6 in Schedule 4 and Appendix D. Peak states that its 10 mg research vial is not a TGA-approved therapeutic good.

Reported side effects

In the 20-person diagnostic study, flushing was the only side effect reported during GHRP-6 administration.
In a sleep and hormone study using four 50 mcg intravenous boluses, mean ACTH rose from 16.6 to 21.0 pg/mL and mean cortisol from 25.2 to 56.0 ng/mL versus placebo; both comparisons were reported as p < 0.02.
Long-term safety is not established: the pharmacokinetic study involved nine healthy men after a single intravenous bolus, rather than repeated use of a research vial.

Important notes

Peak sells this vial strictly for in-vitro laboratory research, not for human or animal consumption, injection, diagnostic or therapeutic use; it is not a TGA-approved therapeutic good.
The current Australian Poisons Standard lists GHRP-6 in Schedule 4 and Appendix D.
Prohibited in sport: WADA's 2026 Prohibited List includes GHRP-6 among growth-hormone-releasing peptides prohibited at all times.
Human research is limited to short physiology, diagnostic and pharmacokinetic work; it does not establish long-term safety or benefits for body composition, recovery or performance.
Never use a mixed vial that is cloudy or has particles in it.

Injection basics

Use a new sterile 1 mL (100-unit) U-100 insulin syringe, 27–31G, every time — never reuse or share.
Wipe the vial stopper and the skin with an alcohol swab and let both dry first.
Inject under the skin (subcutaneously) of the abdomen, thigh or upper arm, and rotate sites.
Put used syringes straight into an approved sharps container — the NDSS lists Australian disposal options.

06 · QUICK ANSWERS

GHRP-6 questions

How many units is 100 mcg of GHRP-6?

With the default 10 mg vial mixed with 3 mL, the concentration is 3.33 mg/mL. A 100 mcg amount is 3 U-100 units (0.03 mL).

How many units is 300 mcg of GHRP-6?

With the default 10 mg vial mixed with 3 mL, 300 mcg is 9 U-100 units (0.09 mL).

How much bacteriostatic water for GHRP-6 10 mg?

The default mix is 3 mL, which makes 3.33 mg/mL. At that concentration, 30 U-100 units (0.30 mL) contains 1 mg.

How long does a 10 mg GHRP-6 vial last?

At the reference schedule's three daily administrations, a nominal 10 mg vial contains 33.3 days at 100 mcg each time, 16.7 days at 200 mcg, or 11.1 days at 300 mcg. Peak says a mixed vial should be used within about 28 days.
