Growth hormone secretagogues (ghrelin receptor) · Ghrelin receptor agonist and growth hormone secretagogue.
- Is GHRP-2 FDA-approved? No FDA-approved product. Japan approves pralmorelin for GH testing. 503B Category 1 covers routes other than injection/nasal; those remain Category 2.
- How do people take it? Under the skin, three times daily. Source: reported by users, not an established dose.
- What's the difference between GHRP-2 and Sermorelin? GHRP-2: a peptide that releases growth hormone and can increase hunger. Sermorelin: an experimental short-acting peptide that triggers growth hormone release, with limited evidence of adult benefits. Why people pair them: the published clinician cohort used all three to raise IGF-1.
- Can I take it with Sermorelin with GHRP-6? The published clinician cohort used all three to raise IGF-1. No control group; safety and body-composition benefits were not established. Source: clinician-published. Ask a doctor before combining anything.
