Also known as. GHRP-2 is also known as pralmorelin. GHRP-6 has no approved pharmaceutical name. Peptide type. Both are hexapeptides. GHRP-2 sequence: D-Ala-D-2Nal-Ala-Trp-D-Phe-Lys-NH2 (817.97 g/mol). GHRP-6 sequence: His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 (873.0 g/m

- Also known as. GHRP-2 is also known as pralmorelin. GHRP-6 has no approved pharmaceutical name.
- Peptide type. Both are hexapeptides. GHRP-2 sequence: D-Ala-D-2Nal-Ala-Trp-D-Phe-Lys-NH2 (817.97 g/mol). GHRP-6 sequence: His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 (873.0 g/mol).
- Receptor target. Both bind the GHS-R1a ghrelin receptor.
- Peak GH release. GHRP-2 produces the highest peak GH release of any traditional GHRP. GHRP-6 delivers robust GH release that is somewhat lower than GHRP-2.
- Appetite stimulation. GHRP-2 produces moderate appetite stimulation, less than GHRP-6. GHRP-6 produces intense hunger — the strongest of any GHRP.
- Cortisol and ACTH elevation. GHRP-2 produces moderate cortisol elevation comparable to hCRH. GHRP-6 produces stronger cortisol elevation, particularly above the saturation dose.
- Prolactin elevation. GHRP-2 produces mild prolactin elevation, lower than TRH-induced. GHRP-6 produces moderate prolactin elevation at higher doses.
- Saturation dose. GHRP-2: approximately 1 to 2 mcg/kg. GHRP-6: approximately 1 mcg/kg.
- Typical dose and frequency. GHRP-2: 100 to 300 mcg per injection, 1 to 3 times daily. GHRP-6: 100 mcg per injection, 2 to 3 times daily.
- Regulatory history. GHRP-2 was approved in Japan in 2004 as a diagnostic agent (pralmorelin). GHRP-6 has no regulatory approval in any country. Neither is FDA-approved. Both are prohibited by WADA under Section S2.
- Best for. GHRP-2 suits maximum GH output with manageable appetite. GHRP-6 suits mass-building phases where appetite stimulation is specifically desired.
