    Is it legal to buy GHRP-6?

    In the United States, GHRP-6 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 GHRP-6 used for in research?

    GHRP-6 is the original growth hormone releasing peptide - the hexapeptide whose discovery in the 1980s first revealed that the ghrelin receptor was a separate, GH-releasing pathway from GHRH. New-U supplies GHRP-6 as research-grade reference material for laboratory and in-vitro or animal-model investigation only. Mechanism, pharmacokinetics and study context are summarised on the GHRP-6 research profile.

    What is the typical GHRP-6 research dosage?

    Reconstitution volumes and dosing reported in the literature for GHRP-6 are described in research-model terms only. New-U Research Compounds supplies GHRP-6 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-6?

    Lyophilised GHRP-6 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-6 online and how fast does it ship?

    Yes. GHRP-6 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-6 in bulk?

    GHRP-6 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-6?

    For research-grade GHRP-6, 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-6 at https://new-u.io/peptide/ghrp-6. A public GHRP-6 certificate is not listed yet; support answers certificate questions from the order reference.

    What is GHRP-6?

    GHRP-6 is the original growth hormone releasing peptide - a synthetic six-amino-acid peptide that binds the ghrelin receptor (GHS-R1a) on the pituitary to trigger a pulse of the body's own growth hormone. It also acts on the CD36 scavenger receptor and is the strongest appetite stimulant of the GHRP family. Supplied as a lyophilised research-grade powder for laboratory use only.

    Why does GHRP-6 cause hunger?

    GHRP-6 is an agonist at the ghrelin receptor GHS-R1a, which is found not only on pituitary somatotrophs (where it releases GH) but also on hypothalamic NPY/AgRP neurons in the arcuate nucleus that regulate appetite. Activating those hypothalamic receptors mimics what natural ghrelin does after a period of fasting - it signals hunger.

    What is the difference between GHRP-6 and GHRP-2?

    Both are hexapeptide ghrelin-receptor agonists. GHRP-6 is the original and the most orexigenic, with a strong hunger signal; GHRP-2 releases more growth hormone per dose with a milder appetite effect. Researchers choose GHRP-6 when the appetite response is wanted and GHRP-2 when GH output without strong hunger is the goal.

    How does GHRP-6 compare with hexarelin and ipamorelin?

    All are ghrelin-receptor agonists. GHRP-6 is the original and most orexigenic; hexarelin is the most potent GH releaser and has the clearest CD36 cardiac profile; ipamorelin is the cleanest and most selective, with minimal cortisol, prolactin, or appetite effect. GHRP-6 sits at the "strong hunger, dual receptor" end of the spectrum.

    What is the half-life of GHRP-6?

    A human pharmacokinetic study reported a biexponential disposition: a short distribution half-life of about 7.6 minutes and an elimination half-life of roughly 2.5 hours after intravenous dosing. The functional growth-hormone effect after subcutaneous injection is short, with the GH peak occurring within about 15-30 minutes.

    Can GHRP-6 be combined with GHRH analogs?

    Yes - this is a standard research stack. GHRP-6 plus a GHRH analogue such as sermorelin or CJC-1295 produces supra-additive GH release because the two peptides activate different receptors (the ghrelin receptor and the GHRH receptor) that converge on GH exocytosis.

    What is the CD36 cardioprotective effect?

    Beyond the pituitary, GHRP-6 binds the CD36 scavenger receptor on heart muscle cells. In preclinical infarction models this activation has been associated with reduced myocardial damage and improved post-infarct remodelling, an effect that is independent of growth-hormone release. These are animal-model findings reported for research context only.

    How should GHRP-6 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-6 is fairly stable in solution within the normal peptide-handling window.
