GHRP-2 – 10MG

Why Buy GHRP-2?

Researchers buy GHRP-2 because it is one of the strongest tools for triggering growth hormone (GH) release in the lab. It (Growth Hormone Releasing Peptide-2) is a synthetic six-amino-acid peptide that binds the ghrelin receptor (GHSR-1a) and makes the pituitary gland release GH, which then raises IGF-1.^[1] Reviv Peptides offers it in Canada as a 10 mg lyophilized (freeze-dried) vial.

As a second-generation GHRP, it makes a stronger, cleaner GH pulse than GHRP-6 with less appetite stimulation. Unlike Ipamorelin, it can also raise cortisol and prolactin a little, so it is studied when a large GH response is the goal.^[1]

Benefits & Uses

GHRP-2 is studied mainly for how it drives the GH/IGF-1 axis. Common research uses include:

• GH secretagogue and GHSR-1a receptor agonism research^[1]
• GH/IGF-1 axis and pulsatile GH release studies^[2]
• Muscle growth and anabolic hormone models
• Fat breakdown (lipolysis) research
• Sleep pattern and GH pulse studies
• Combined GHRP + GHRH synergy research (with CJC-1295)^[2]

How It Works

GHRP-2 works by binding the GHSR-1a receptor on the GH-making cells of the pituitary. This triggers a rise in intracellular calcium and activates PKC, which pushes GH out of the cell.^[2] It also acts in the hypothalamus to lower somatostatin, the hormone that normally puts the brakes on GH. With less braking, the GH pulse gets bigger.^[1] When it is paired with a GHRH analog, the two work through different receptors at the same time — GHRH opens the gate while GHRP-2 releases the brake — making a large GH spike often used in research models.^[2]

Frequently Asked Questions

How does it differ from GHRP-6?

The main difference is the side effects. GHRP-2 makes a larger GH pulse with less appetite and cortisol effect than GHRP-6.^[1] This makes it cleaner for studies that focus only on the GH axis, while GHRP-6’s strong ghrelin (hunger) activity makes it more useful for appetite and gut research.

Is GHRP-2 often used with CJC-1295?

Yes. GHRP-2 (a GHSR agonist) and CJC-1295 (a GHRH analog) act through two different receptor systems, so together they make synergistic GH pulses.^[2] This pairing is a common research protocol for GH axis studies.

Is GHRP-2 available in Canada?

Yes. Reviv Peptides ships it across Canada.

Reconstitution & Dosing Guide

How to Reconstitute

Add 3.0 mL of bacteriostatic water to the vial. Inject the water slowly down the inside wall of the vial — do not spray it onto the powder. Gently swirl until it fully dissolves; do not shake. This gives about 3.33 mg/mL. Store the mixed vial at 4 °C and use within 28 days.

Low Starting Dose

• Dose per injection: 100 mcg — 3 units (0.03 mL) on a U-100 insulin syringe
• Frequency: Once daily, subcutaneous injection (preferably before sleep)
• Cycle length: 8–12 weeks
