What is GHRP-6?

GHRP-6 (Growth Hormone–Releasing Peptide-6) is a synthetic hexapeptide and ghrelin receptor agonist (GHS-R1a) that promotes natural growth hormone (GH) secretion through stimulation of the hypothalamic–pituitary axis. It belongs to the GHRP family of peptides (including GHRP-2 and Ipamorelin) and is widely researched for its effects on growth hormone release, recovery, body composition, and immune balance. In addition to GH stimulation, GHRP-6 is known to influence appetite regulation, metabolic homeostasis, and cellular repair, making it valuable in studies on aging, energy metabolism, and recovery physiology.

FAQ

How much is in each vial?

Each vial contains precisely the amount indicated on the label. For instance, a 10mg vial includes precisely 10mg of lyophilized peptide. Researchers may divide it into smaller fractions, such as four 2.5mg portions, while the total amount remains 10mg.

Does it come with instructions?

USA Peptides Direct products are designated for in vitro research. Prior to working with them, conduct thorough research. Our team will offer general assistance via text post-purchase.

What other supplies are needed?

Peptides come as lyophilized powder. They are not reconstituted, and any necessary bacteriostatic water or syringes must be obtained separately for research purposes.

How long does a vial last?

Peptides remain stable for up to 2 years in lyophilized powder form. After reconstitution, refrigerate and expect stability for about 2 months.

Is GHRP-6 the same as GHRP-2?

No. GHRP-2 (Pralmorelin) is a different hexapeptide. GHRP-6 has the sequence His-D-Trp-Ala-Trp-D-Phe-Lys-NH2; verify performance in your specific assay format.

What purity do you provide?

Each 10 mg vial is ≥99% by HPLC with MS identity confirmation; third-party testing is performed on every lot (COA via on page).

How should I reconstitute it?

Dissolve in sterile water or a compatible buffer; gently invert until fully dissolved. If your protocol requires sterility, pass through a 0.22 µm filter and aliquot to avoid repeat freeze–thaw.

Which in-vitro assays is GHRP-6 commonly used in?

Typical RUO uses include GHSR Ca2+/IP-One assays, β-arrestin/internalization workflows, binding/competition experiments, and HPLC/LC–MS method development.
