GHRP-2 Injectable Peptide
GHRP-2 is a synthetic hexapeptide that acts as a growth hormone secretagogue, binding to the ghrelin receptor (GHS-R1a) to stimulate pituitary growth hormone release. It is commonly referenced in research contexts as a potent GH-releasing peptide, positioned between ipamorelin and GHRP-6 in terms of selectivity versus potency.
In clinical research settings, GHRP-2 has been studied for its ability to stimulate GH secretion and its effects on appetite regulation. The peptide has received regulatory approval in Japan as a diagnostic agent for growth hormone deficiency testing, though it is not FDA-approved for any indication in the United States. In non-medical bodybuilding and performance contexts, GHRP-2 is commonly referenced for its GH-stimulating properties and moderate appetite effects.
Unlike GHRP-6, which produces significant appetite stimulation and minimal cortisol/prolactin elevation, GHRP-2 offers a more balanced profile. It produces potent GH release with moderate cortisol and prolactin increases, making it a middle-ground option among growth hormone secretagogues. This balance between potency and selectivity is a defining characteristic of the compound.
Key Benefits of GHRP-2 5 mg
- Potent growth hormone release via ghrelin receptor activation
- Moderate appetite stimulation compared to GHRP-6
- Balanced selectivity and potency profile among GHRPs
- Commonly stacked with GHRH analogs for synergistic effect
- Lyophilized powder form for reconstitution flexibility
Growth Hormone Secretagogue (Ghrelin Receptor Agonist)
GHRP-2 acts primarily on the growth hormone secretagogue receptor (GHS-R1a), also known as the ghrelin receptor. Activation of this receptor in the pituitary and hypothalamus triggers growth hormone release through mechanisms that are additive with GHRH analogs.
The GH pulse produced by GHRP-2 is short-lived, typically peaking within 15–30 minutes after administration and returning to baseline within a few hours. This pulsatile release pattern mimics the body's natural GH secretion rhythm and is why multiple daily doses are commonly referenced in community protocols.
Compared to GHRP-6, GHRP-2 produces similar GH release with less pronounced appetite stimulation. Compared to ipamorelin, GHRP-2 is more potent but less selective, with moderate elevations in cortisol and prolactin.
Release Profile
Pulsatile GH Release
GHRP-2 produces a rapid, short-lived GH pulse after subcutaneous administration. This pulsatile pattern is distinct from the sustained elevation produced by GHRH analogs like CJC-1295 with DAC, and is why GHRP-2 is commonly stacked with GHRH analogs for synergistic effect.
GHRP-2 5 mg vs Other Dragon Pharma Preparations
Dragon Pharma offers several peptide preparations that are commonly referenced alongside GHRP-2 in research and bodybuilding contexts. The CJC-DAC provides a long-acting GHRH analog that is frequently stacked with GHRP-2 for enhanced GH release. Ipamorelin offers a more selective alternative with minimal cortisol and prolactin effects. GHRP-6 provides a more potent appetite-stimulating alternative with a similar GH release profile. For those interested in the GHRH analog without DAC, CJC 1295 No DAC/Ipamorelin is a pre-mixed combination option.

Stacking & Cycle Considerations
GHRP-2 is commonly stacked with GHRH analogs such as CJC-DAC or Mod GRF 1-29 to produce synergistic GH release. The combination of a GHRP and a GHRH analog stimulates GH through complementary mechanisms, producing a larger pulse than either alone.
Community protocols typically reference cycles of 8–12 weeks followed by a break, though this practice is based on community experience rather than validated clinical protocols. Rotating between different GHRPs (such as GHRP-2 and Ipamorelin) is sometimes referenced to limit potential receptor desensitization.
Managing Side Effects
The most commonly referenced side effects of GHRP-2 include increased appetite, mild cortisol and prolactin elevation, and injection-site reactions. Appetite stimulation is less pronounced than with GHRP-6 but more noticeable than with ipamorelin.
Doses are typically timed away from food, as elevated blood glucose and insulin can blunt the GH response. Fasting for 1–2 hours before and 30–60 minutes after injection is commonly referenced in community protocols.
Post-Cycle Therapy (PCT)
GHRP-2 does not suppress endogenous testosterone production and therefore does not typically require post-cycle therapy in the way anabolic steroids do. However, some individuals may choose to use supportive compounds based on individual circumstances.
Since GHRP-2 works through the ghrelin receptor rather than directly affecting the hypothalamic-pituitary-gonadal axis, PCT is generally not considered necessary after GHRP-2 use alone.
Important
Individual Response Varies
Dosing strategies and cycle protocols should be adjusted based on individual factors. The information above is for educational reference and does not constitute medical advice.
Important Safety Information
GHRP-2 is a synthetic peptide that stimulates growth hormone release through ghrelin receptor activation. It is not approved for therapeutic use in the United States. In research settings, it has been studied for diagnostic applications, but repeated daily use for performance or physique enhancement falls outside any approved framework.
Because toxicological data for this peptide are incomplete, it should be treated as a potentially bioactive substance of unknown toxicity. Appropriate precautions should be taken when handling the lyophilized powder.
Important
Non-Medical Use
GHRP-2 is not FDA-approved for human use. Any use outside of approved diagnostic applications falls outside approved indications. Product concentration and laboratory verification do not establish that non-medical use is safe or appropriate for an individual.
Potential Adverse Effects
GHRP-2 stimulates GH release and can produce moderate elevations in cortisol and prolactin levels. Community reports commonly reference increased appetite, injection-site reactions, and occasional feelings of fatigue or lightheadedness after administration.
Because GHRP-2 acts on the ghrelin receptor, it may affect appetite regulation and gastric motility. Individuals with conditions sensitive to these effects should exercise caution.
As with any injectable peptide, proper sterile technique and product handling are important to minimize risk of contamination or injection-site complications.
Conditions Requiring Medical Evaluation
Individuals with existing endocrine disorders, pituitary conditions, or hormone-sensitive conditions should consult a qualified healthcare professional before considering GHRP-2. The long-term effects of chronic GHRP-2 use have not been established.
Because GHRP-2 can affect cortisol and prolactin levels, individuals with conditions sensitive to these hormones should exercise particular caution.
Monitoring During Use
In research settings where GHRP-2 has been studied, monitoring has focused on GH response, cortisol, and prolactin levels. In non-medical contexts, individuals commonly reference periodic bloodwork to monitor hormonal markers.
Laboratory testing of the product itself, such as the published potency report shown in the Lab Reports tab, is separate from any clinical monitoring of the individual.

What is GHRP-2 5 mg used for?
GHRP-2 5 mg contains pralmorelin, a growth hormone secretagogue peptide. In research settings it is used to stimulate GH release via ghrelin receptor activation. In non-medical bodybuilding contexts, GHRP-2 is commonly referenced for its GH-stimulating properties, though such use falls outside approved indications.
How often should GHRP-2 5 mg be injected?
Community protocols commonly reference GHRP-2 being injected 1–3 times daily at doses of 100–200 mcg per injection. Doses are typically timed on an empty stomach to maximize the GH response. The GH pulse from GHRP-2 is short-lived, which is why multiple daily doses are used to create multiple pulses.
Does GHRP-2 5 mg require PCT?
GHRP-2 does not suppress endogenous testosterone production because it acts on the ghrelin receptor rather than directly affecting the hypothalamic-pituitary-gonadal axis. Post-cycle therapy is therefore generally not considered necessary after GHRP-2 use alone.
What does GHRP-2 do?
GHRP-2 stimulates growth hormone release by activating the ghrelin receptor (GHS-R1a) in the pituitary and hypothalamus. This produces a pulsatile GH release that mimics the body's natural secretion pattern. GHRP-2 also has moderate effects on appetite, cortisol, and prolactin.
How long does GHRP-2 take to work?
The GH pulse from a single GHRP-2 injection typically peaks within 15–30 minutes and returns to baseline within a few hours. Effects on GH levels are therefore acute and short-lived with each dose. Any cumulative effects on physique or recovery would develop over weeks of consistent use.
Is GHRP-2 the best GH secretagogue?
There is no single GH secretagogue that is universally best. GHRP-2 occupies a middle ground between Ipamorelin (more selective, less potent) and GHRP-6 (more potent, more appetite stimulation). The appropriate choice depends on individual goals and priorities.
What is the difference between GHRP-2 and GHRP-6?
Both GHRP-2 and GHRP-6 are growth hormone secretagogues, but they differ in their side effect profiles. GHRP-6 produces more pronounced appetite stimulation, while GHRP-2 has a more moderate effect on appetite. GHRP-2 is generally considered more selective with less cortisol and prolactin elevation than GHRP-6.
What is the difference between GHRP-2 and Ipamorelin?
GHRP-2 is more potent for GH release but less selective, producing moderate cortisol and prolactin elevations. Ipamorelin is more selective with minimal effects on these hormones but produces a smaller GH pulse. GHRP-2 is positioned between ipamorelin and GHRP-6 in terms of selectivity versus potency.
Is 100 mcg of GHRP-2 a lot?
100 mcg is commonly referenced as the saturation dose for GHRP-2, meaning the point beyond which additional peptide produces diminishing GH response. Doses of 100–200 mcg per injection are typical in community protocols. The 5 mg vial contains 5,000 mcg total, providing 25–50 doses at these levels.
What strength is GHRP-2 5 mg?
GHRP-2 5 mg is labeled at 5 mg of GHRP-2 per vial. It is supplied as a lyophilized powder in a 2 mL vial, requiring reconstitution before use.
Is GHRP-2 5 mg lab tested?
Yes. A published laboratory report dated November 7, 2025 measured GHRP-2 5 mg at 5.88 mg, equivalent to 117.6% of its 5 mg label claim. The batch number for this report is #HDGH10.
The complete report can be viewed in the Lab Reports tab. Laboratory results apply to the tested sample represented by the individual report and should not be interpreted as a measurement of every vial.
How should GHRP-2 5 mg be reconstituted?
Lyophilized GHRP-2 is typically reconstituted with a suitable solvent such as Bacteriostatic Water or sterile water. The volume of solvent added determines the concentration of the resulting solution. Proper sterile technique should be used during reconstitution.
