What is GHRP-2?
What GHRP-2 research examines
Summarised from published preclinical and clinical literature; findings describe study models, not uses of the research material.
GHRP-2 price and pack sizes
All packs are >99% HPLC research-grade material. Cost per mg is the price divided by the total mg in the pack. Single vials ship only as an add-on to an order that includes a 10-vial research pack. Flat $35 USD worldwide · free over $350 USD.
GHRP-2 certificate status
Every released sale batch must pass independent verification before it is offered for sale. A public certificate for GHRP-2 is not listed yet. Contact support with your order reference if a public certificate for your compound is not yet listed.
Mechanism summary
GHRP-2 activates the ghrelin receptor on pituitary somatotrophs, triggering a sharp GH pulse with modest increases in cortisol and prolactin.

Frequently asked questions
Where can I buy GHRP-2?
GHRP-2 (also known as Pralmorelin) is available directly from New-U Research Compounds at https://new-u.io/peptide/ghrp-2. It is supplied as lyophilised research-grade material; every released sale batch is independently verified by Janoshik Analytical and Freedom Diagnostics before it is offered for sale, and orders ship direct from source worldwide (approximately 6–14 business days).
How much does GHRP-2 cost?
GHRP-2 starts at $104 for a 10-vial research pack (10mg per vial) at New-U Research Compounds, with 2 pack sizes listed; single vials from $31 ship as an add-on to a pack order. Orders over $350 ship free.
Is New-U GHRP-2 third-party tested?
Yes. Released GHRP-2 batches are verified by independent laboratories (Janoshik Analytical and Freedom Diagnostics) for identity and purity before they are offered for sale. A public certificate for GHRP-2 is not listed yet. Contact support with your order reference if a public certificate for your compound is not yet listed.
How fast does GHRP-2 ship, and do you ship internationally?
GHRP-2 ships discreetly and tracked worldwide. US orders ship from the USA or China depending on stock and fulfilment; all other destinations ship from China, direct from the manufacturer. Delivery takes approximately 6–14 business days worldwide. Shipping is free on orders over $350. Card and cryptocurrency payments are accepted.
Is it legal to buy GHRP-2?
In the United States, GHRP-2 is not approved by the FDA for human consumption and is not sold for that purpose. Research use only - all claims made on this site are for testing and research use only. Regulatory requirements vary by product, intended use and jurisdiction. Purchasers are responsible for ensuring that acquisition and use of research material complies with applicable requirements.
What is the typical GHRP-2 research dosage?
Reconstitution volumes and dosing reported in the literature for GHRP-2 are described in research-model terms only. New-U Research Compounds supplies GHRP-2 strictly for laboratory research and does not provide human-use dosing guidance. Reconstitution math and study-reported ranges are covered on the full research profile.
What do I use to reconstitute GHRP-2?
Lyophilised GHRP-2 is reconstituted with bacteriostatic water - sterile water with 0.9% benzyl alcohol, the standard multi-use diluent for research peptides. New-U supplies USP-grade bacteriostatic water at https://new-u.io/peptide/bacteriostatic-water, and a free reconstitution calculator at https://new-u.io/tracker/calculator works out the volume for any peptide.
Can I buy GHRP-2 online and how fast does it ship?
Yes. GHRP-2 can be ordered online directly from New-U Research Compounds with card or cryptocurrency, shipped direct from source discreetly worldwide. Delivery is approximately 6–14 business days worldwide. Free shipping applies to orders over $350.
Can I buy GHRP-2 in bulk?
GHRP-2 ships in 10-vial research packs as standard, in 2 pack sizes — the larger mg vials lower the per-mg cost. Multi-pack orders get direct-from-source pricing and free shipping over $350. For wholesale or recurring laboratory-supply volumes, contact New-U Research Compounds at https://new-u.io/contact.
What should I look for when choosing where to buy GHRP-2?
For research-grade GHRP-2, verify four things: (1) independent third-party purity testing with a published Certificate of Analysis - New-U uses Janoshik Analytical and Freedom Diagnostics; (2) lyophilised material with documented storage and handling; (3) transparent direct-from-source pricing rather than marketplace markup; and (4) clear research-use-only framing. New-U Research Compounds lists GHRP-2 at https://new-u.io/peptide/ghrp-2. A public GHRP-2 certificate is not listed yet; support answers certificate questions from the order reference.
What is GHRP-2?
GHRP-2 (pralmorelin) is a synthetic six-amino-acid growth hormone secretagogue that binds the ghrelin receptor (GHS-R1a) on the pituitary to trigger a sharp pulse of the body's own growth hormone. It is the first GH secretagogue to gain any regulatory approval, used as a GH-deficiency diagnostic in Japan. Supplied here as a lyophilised research-grade powder for laboratory use only.
What is the difference between GHRP-2 and GHRP-6?
Both are hexapeptide ghrelin-receptor agonists, but GHRP-2 releases more growth hormone per dose while producing a milder appetite (orexigenic) effect. GHRP-6 is the original of the family and the strongest hunger stimulant. Researchers reach for GHRP-2 when they want GH output without the pronounced appetite signal of GHRP-6.
How does GHRP-2 compare with ipamorelin?
GHRP-2 is a stronger GH releaser per dose, but it also produces modest cortisol, ACTH, and prolactin elevation that ipamorelin does not. Ipamorelin is cleaner and more selective; GHRP-2 is more potent and has a richer clinical pharmacokinetic dataset. The choice depends on whether the research protocol prioritises selectivity or potency.
What is the half-life of GHRP-2?
GHRP-2 is short-acting, with a functional half-life on the order of 15-30 minutes. The growth-hormone pulse it triggers typically peaks around 15 minutes after subcutaneous administration and returns toward baseline within roughly an hour, which is why research protocols describe multiple separated doses rather than a single sustained one.
Does GHRP-2 increase appetite?
Moderately. GHRP-2 activates hypothalamic ghrelin receptors enough to produce a noticeable increase in hunger in research subjects, but less dramatically than GHRP-6, which is the strongest orexigenic member of the family. The appetite effect is a direct consequence of acting on the same receptor as natural ghrelin.
Why is GHRP-2 stacked with CJC-1295?
GHRP-2 and CJC-1295 (a GHRH analogue) act on two different receptors - the ghrelin receptor and the GHRH receptor - that converge on growth-hormone release. Combining them in research models produces a larger, cleaner GH pulse than either peptide alone, which is the standard rationale for pairing a GHRP with a GHRH analogue.
Can GHRP-2 be dosed orally?
Oral bioactivity has been demonstrated across multiple species, though absolute oral bioavailability is quite low (roughly 0.3%). That means meaningful oral exposure requires much larger amounts than subcutaneous or IV, but the route does function in research protocols, and intranasal delivery has also been validated.
How should GHRP-2 be stored?
Keep the lyophilised powder frozen at −20 °C. After reconstitution with bacteriostatic water, refrigerate at 1-6 °C and protect from light. GHRP-2 is reasonably stable in solution within the standard peptide-handling window.
