Side-by-side comparison of key properties, dosing, and research.

Growth Hormone Peptides
MK-677 (Ibutamoren)
Cognitive EnhancementAnti-Aging & Longevity
Pinealon
Summary
MK-677 (Ibutamoren) is an orally active, non-peptide ghrelin receptor agonist that increases growth hormone and IGF-1 levels. Unlike injectable GHRPs, it can be taken orally and has a 24-hour half-life, making it convenient for sustained GH optimization.
Pinealon is a synthetic tripeptide (Glu-Asp-Arg) developed by the St. Petersburg Institute of Bioregulation, designed to penetrate the blood-brain barrier and exert neuroprotective, neurogenic, and anti-aging effects by regulating pineal gland and brain cell function.
