Product Overview
GHRP-2 5 mg by Peptide Hubs
GHRP-2 5 mg is a lyophilized growth hormone secretagogue research product manufactured by Peptide Hubs and supplied as a 5 mg/vial powder in a 2 mL vial.
GHRP-2 Injectable
GHRP-2 5 mg contains pralmorelin, a synthetic hexapeptide that acts as a growth hormone secretagogue (GHS) . Also known as Growth Hormone Releasing Peptide-2, it is an agonist of the ghrelin receptor (GHS-R1a), which is expressed in the pituitary and hypothalamus. GHRP-2 was developed as a diagnostic agent for growth hormone deficiency and is approved for this purpose in Japan, though it has not received FDA approval in the United States.
GHRP-2 stimulates endogenous GH release through a mechanism distinct from GHRH analogs like CJC-1295. It activates the ghrelin receptor pathway, which is also involved in appetite regulation. This dual effect on GH secretion and appetite is a defining characteristic of GHRP-2 compared to more selective secretagogues like ipamorelin.
Clinical research on GHRP-2 has primarily focused on its diagnostic use for GH deficiency testing. A study in children with short stature found that intranasal GHRP-2 stimulated prompt GH discharge but did not produce sustained GH elevation sufficient to promote growth. The FDA has documented serious adverse events including death associated with GHRP-2 in its regulatory review of peptide safety data.

Formulation
Lyophilized Powder
GHRP-2 5 mg is supplied as a lyophilized (freeze-dried) powder in a 2 mL vial. Reconstitution with an appropriate solvent is required before use in research contexts.
Product Profile
GHRP-2 Profile
GHRP-2 (pralmorelin) is a synthetic hexapeptide with a molecular weight of approximately 818 Da and the molecular formula C45H55N9O6. Its amino acid sequence is D-Ala-D-2Nal-Ala-Trp-D-Phe-Lys-NH2.
Ghrelin Receptor Agonist
GHRP-2 belongs to the class of growth hormone secretagogues (GHS), which stimulate GH release through activation of the ghrelin receptor (GHS-R1a). This mechanism is distinct from GHRH analogs such as CJC-1295 or sermorelin, which act through the GHRH receptor.
GHRP-2 induces GH release from pituitary cells and has been shown to increase blood GH levels in animal models. Unlike more selective GHRPs like ipamorelin, GHRP-2 also stimulates appetite through its ghrelin receptor activity. This appetite-stimulating effect has been observed in human studies.
In non-medical bodybuilding contexts, GHRP-2 is commonly referenced for GH release and appetite stimulation. However, the FDA has documented serious adverse events including death associated with GHRP-2. The compound is not approved for any human indication in the United States.
Defining Characteristic
Dual GH and Appetite Effects
GHRP-2 is distinguished from other GH secretagogues by its pronounced appetite-stimulating effect, which results from its ghrelin receptor agonism. This contrasts with ipamorelin, which is more selective for GH release with minimal appetite effects.
GHRP-2 5 mg vs Other Peptide Hubs Preparations
Peptide Hubs offers several growth hormone secretagogues for research. Within this lineup, Ipamorelin is a more selective GHRP that produces GH release with minimal effects on appetite and cortisol. GHRP-2 is commonly compared to this compound, with the primary difference being GHRP-2's appetite-stimulating effect.
For research focused on GHRH receptor pathways rather than ghrelin receptor pathways, CJC-1295 No DAC represents a different mechanism of GH stimulation. For pre-mixed combinations, CJC-1295/Ipamorelin provides a dual-pathway approach. GHRP-6 is another ghrelin receptor agonist with even more pronounced appetite effects.

Dosage & Usage
GHRP-2 5 mg Dosage & Usage
The information below is provided for educational reference only. GHRP-2 is not FDA-approved for any human use in the United States. Its use for any non-medical purpose falls outside approved indications, and no established human dosing regimen exists for bodybuilding or performance contexts.
Typical Dosage Ranges
Because GHRP-2 lacks FDA approval and published human dose-finding trials for non-diagnostic applications, there is no medically established dosage range for research or bodybuilding contexts. In non-medical research communities, reference ranges are derived from community convention. Commonly referenced ranges are 100–300 mcg per injection, administered 1–3 times daily.
| Use Case | Common Reference Range | Injection Frequency |
|---|---|---|
| Standard research protocol (non-medical) | 100–200 mcg | 1–3 times daily |
| Combined with CJC-1295 (non-medical) | 100 mcg GHRP-2 + CJC | 1–2 times daily |
| Upper range (non-medical) | 300 mcg | Once daily |
Community protocols commonly reference dosing in a fasted state, typically before bed and/or post-workout to align with natural GH pulses.
Reconstitution & Handling
GHRP-2 5 mg is supplied as a lyophilized powder and requires reconstitution before use. A 5 mg vial reconstituted with 2 mL of solvent yields a concentration of 2.5 mg/mL (2,500 mcg/mL), meaning a 100 mcg dose would require drawing 0.04 mL (4 units on a U-100 insulin syringe).
Reconstituted solution should be stored refrigerated at 2–8°C and protected from light. Avoid repeated freeze-thaw cycles.
Stacking & Cycle Considerations
In non-medical bodybuilding contexts, GHRP-2 is sometimes combined with GHRH analogs such as CJC-1295 No DAC for potential synergistic GH release through parallel pathways. Cycle lengths commonly referenced range from 8 to 12 weeks on, followed by a 4-week break.
For research comparing different ghrelin receptor agonists, Ipamorelin offers a more selective alternative with less appetite stimulation.
Important
Individual Response Varies
No human dose-response data for therapeutic outcomes exists for GHRP-2 in non-medical contexts. All dosage information is derived from community convention and should not be interpreted as medical guidance.
Safety & Information
GHRP-2 Safety Information
GHRP-2 is not FDA-approved for any human use in the United States. The FDA has documented serious adverse events including death associated with GHRP-2 in its regulatory review of peptide safety data.
Important Safety Information
GHRP-2 has not received FDA approval. The FDA’s 2023 review of peptide safety data documented serious adverse events including death associated with GHRP-2, and also noted immunogenicity risk from impurities and aggregation. GHRP-2 is approved in Japan only as a diagnostic agent for GH deficiency testing.
As a peptide administered parenterally, GHRP-2 may pose immunogenicity risks. The FDA has raised concerns about the lack of characterization data for GHRP-related substances, including critical data on impurities, aggregates, and endotoxins.
Important
Non-Medical Use
GHRP-2 is marketed as a research peptide, but it is not FDA-approved for any human indication. Non-medical use falls outside approved indications and carries documented serious risks.
Potential Adverse Effects
Short-term clinical studies of GHRP-2 have reported increases in appetite, transient prolactin elevations, and no significant weight changes. However, the FDA’s regulatory review documented serious adverse events including death associated with GHRP-2.
Community discussions of GHRP-2 mention potential water retention, joint stiffness, and numbness/tingling in extremities, though these reports are anecdotal. Injection site reactions are commonly reported with peptide injections.
Conditions Requiring Medical Evaluation
Given the documented serious adverse events and absence of long-term safety data, any consideration of GHRP-2 use should involve consultation with a qualified healthcare professional. Individuals with a history of cancer or strong family history of malignancy should exercise particular caution due to theoretical mitogenic concerns with GH/IGF-1 signaling.
Monitoring During Use
No established monitoring protocol exists for non-medical GHRP-2 use. Clinicians evaluating patients using GH-related peptides should consider monitoring IGF-1 levels, blood glucose, and potential injection site reactions.

Frequently Asked Questions
GHRP-2 5 mg FAQ
Answers to common questions about GHRP-2 5 mg, Pralmorelin, and research peptide handling.
What is GHRP-2 5 mg used for?
GHRP-2 5 mg contains pralmorelin, a ghrelin receptor agonist studied for its ability to stimulate endogenous growth hormone release. It is approved in Japan as a diagnostic agent for GH deficiency testing. In non-medical bodybuilding contexts, it is commonly referenced for GH release and appetite stimulation, though such use falls outside approved indications.
How often should GHRP-2 5 mg be injected?
No established human dosing schedule exists for non-diagnostic use. Community protocols commonly reference 1–3 daily subcutaneous injections at 100–300 mcg per dose, based on convention rather than clinical outcome data.
Does GHRP-2 5 mg require PCT?
GHRP-2 does not suppress endogenous testosterone production and does not require post-cycle therapy in the way anabolic steroids do. However, any non-medical peptide use should be approached with caution given the documented serious adverse events including death associated with GHRP-2.
What does Pralmorelin do?
Pralmorelin (GHRP-2) is a synthetic ghrelin receptor agonist that stimulates growth hormone release from the pituitary. Unlike GHRH analogs, it also increases appetite through its ghrelin receptor activity.
How long does GHRP-2 take to work?
GHRP-2 produces a prompt GH discharge after administration, but the effect is transient. A clinical study in children found that intranasal GHRP-2 stimulated GH release but did not produce sustained elevation sufficient to promote growth.
Is GHRP-2 the best GH secretagogue?
There is no universally “best” GH secretagogue. GHRP-2 produces GH release with significant appetite stimulation, while Ipamorelin is more selective for GH release with minimal appetite effects. The appropriate choice depends on the specific research context.
What is the difference between GHRP-2 5 mg and Ipamorelin?
GHRP-2 and Ipamorelin both act through the ghrelin receptor, but GHRP-2 has more pronounced appetite-stimulating effects while Ipamorelin is more selective for GH release with minimal cortisol and prolactin effects.
What is the difference between GHRP-2 5 mg and CJC-1295 No DAC?
GHRP-2 acts through the ghrelin receptor (GHS-R1a), while CJC-1295 No DAC acts through the GHRH receptor. They target different pathways and are sometimes combined in research protocols for potential synergistic GH release.
Is 300 mcg of GHRP-2 a lot?
300 mcg is at the upper end of the range commonly referenced in community protocols (100–300 mcg per injection). The GH response to GHRP-2 is described as saturable, meaning higher doses do not necessarily produce proportionally greater effects.
What strength is GHRP-2 5 mg?
GHRP-2 5 mg is labeled at 5 mg of pralmorelin per vial. It is supplied as a lyophilized powder in a 2 mL vial.
Is GHRP-2 5 mg lab tested?
Yes. A published laboratory report dated November 26, 2025 measured GHRP-2 5 mg at 6.20 mg, equivalent to 124.0% of its 5 mg label claim. The batch number is GAGHRP2-11.
How should GHRP-2 5 mg be stored?
Store the lyophilized powder at -20°C, sealed, dry, and protected from light. Once reconstituted, refrigerate at 2–8°C and use within the recommended timeframe. Avoid repeated freeze-thaw cycles.
