GHRP-2 by Dragon Pharma
What Is GHRP-2?
GHRP-2 by Dragon Pharma is a growth hormone releasing peptide from the GHRP family, related to ghrelin and designed to stimulate the pituitary to release natural growth hormone. It is one of the more potent secretagogues per microgram and is a staple of GH research protocols, valued for supporting the body's own release rather than replacing it with exogenous hormone.
Each vial holds 5 mg of lyophilized GHRP-2 powder for reconstitution with bacteriostatic water. Because it is a short-acting peptide, research dosing is split across the day - typically 100-300 mcg per injection, two to three times daily, most often pre-bed and post-workout or around other low-insulin windows. The 5 mg vial lasts roughly a week to ten days at those reference doses.
Compared with GHRP-6, GHRP-2 is commonly described as more potent at lower doses, with milder appetite stimulation and less effect on cortisol and prolactin. That makes it a popular middle ground for researchers who want a strong natural GH pulse without the strong hunger signal of GHRP-6.
GHRP-2 Research Use
GHRP-2 protocols follow the standard secretagogue model: reconstitute the lyophilized peptide, dose in micrograms with an insulin syringe and schedule injections around low-insulin windows so the natural GH pulse is as strong as possible.
| Parameter | Reference value | Note |
|---|---|---|
| Reconstitution | 1-2 ml bacteriostatic water | Gives a clear mcg per unit concentration for dosing |
| Research dose | 100-300 mcg per injection | Start at the lower end and assess the response |
| Frequency | 2-3 injections per day | Pre-bed and around training are common slots |
| Vial lifetime | 5-10 days at typical doses | 5,000 mcg total per 5 mg vial |
| Research window | 8-12 weeks with breaks | Rest the GH axis between research blocks |
Practical Notes
Secretagogues release best when insulin and glucose are low, so a two-hour fast before each dose is the standard reference. GHRP-2 is more forgiving on appetite than GHRP-6, but it still works through the same ghrelin pathway, so timing and total daily dose matter for a clean research outcome.
GHRP-2 Stacks
GHRP-2 is almost always run together with a GHRH-class peptide, because the two stimulate growth hormone through different signals and together produce a stronger, wider pulse. All partners below are Dragon Pharma products.
| Stack partner | Role in the stack |
|---|---|
| CJC-1295 no DAC/Ipamorelin 10mg | Short GHRH partner for clean daily pulses |
| CJC-1295 Dac 5mg | Long-acting GHRH for sustained GH output |
| Sermorelin | Milder GHRH option for longer research blocks |
| Ipamorelin | Cleaner secretagogue for sensitive researchers |
| GHRP-6 10 mg | Secretagogue alternative when appetite support is wanted |
| Hexarelin 5 mg | Heavier GHRP-family option for stronger pulses |
A standard reference pairing is GHRP-2 with a no-DAC CJC-1295 or ipamorelin partner, injected together two to three times a day. Because the pulse is shared, many protocols keep the GHRP-2 side of the dose moderate rather than maximal.
GHRP-2 Side Effects
GHRP-2 is generally well tolerated and is often described as the cleaner option in the GHRP family, but it is not free of effects.
- Appetite: a mild to moderate hunger increase can occur; usually less pronounced than with GHRP-6.
- Cortisol and prolactin: can rise at higher doses; keeping the dose controlled and the research window limited is the standard management.
- Water retention: transient puffiness or facial fullness is reported early in a run.
- Injection site: occasional local reaction; rotate sites and reconstitute with quality bacteriostatic water.

What is GHRP-2?
GHRP-2 is a synthetic growth hormone releasing peptide from the GHRP family, related to the natural hormone ghrelin. It stimulates the pituitary to release growth hormone and is one of the more potent secretagogues per microgram.
What does GHRP-2 do?
GHRP-2 stimulates natural growth hormone pulses, which research connects to improved recovery, deeper sleep, better tissue repair and a more favorable training environment. It supports the body's own GH output rather than replacing it with exogenous hormone.
What is the difference between GHRP-2 and GHRP-6?
GHRP-2 is generally considered more potent at lower doses, with milder appetite stimulation and less effect on cortisol and prolactin. GHRP-6 is known for a strong hunger signal and is often chosen when appetite support is a goal.
How much GHRP-2 should I take?
Reference research protocols typically use 100-300 mcg per injection, two to three times per day. A first research run should start at the lower end to assess individual response before adjusting.
How often do you inject GHRP-2?
Because GHRP-2 is short acting, the standard schedule is 2-3 subcutaneous injections per day, usually pre-bed and around training or meals that are followed by a fasting window. Frequency matters more than with long-acting GH compounds.
Does GHRP-2 need to be taken on an empty stomach?
Yes, that is the reference standard. GH peptides release best when glucose and insulin are low, so most protocols use a two-hour fast before each dose to get the strongest natural pulse.
Does GHRP-2 cause hunger?
It can, but less than GHRP-6. The appetite increase comes from the ghrelin pathway and is usually mild to moderate, which is one reason researchers who want clean pulses without a strong hunger signal prefer GHRP-2.
What are the side effects of GHRP-2?
Reported effects include mild hunger, transient water retention, flushing and occasional injection-site reaction. Cortisol and prolactin can rise at higher doses, which is why dosing stays controlled and research windows include breaks.
How long does a 5 mg GHRP-2 vial last?
The 5 mg vial holds 5,000 mcg. At a typical 100-200 mcg dose two to three times a day it lasts roughly 5-10 days of research use, depending on the exact protocol.
