MK-677 Powder (Istobal/Nutrobal)

$35.00

MK-677 (Ibutamoren), also known as Istobal or Nutrobal, is a highly pure, orally bioavailable growth hormone secretagogue (GHS) supplied as a white to off-white crystalline powder with ≥99% purity. It stimulates the release of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) by mimicking the action of the endogenous hormone ghrelin, without affecting cortisol levels. MK-677 is widely used in research focused on muscle growth, metabolic regulation, bone density, and anti-aging mechanisms. Packaged discreetly and shipped worldwide with fast delivery.

Introduction

MK-677 (Ibutamoren) is a potent, long-acting, orally active non-peptide growth hormone secretagogue that selectively activates the ghrelin receptor (GHS-R1a). By stimulating the pituitary gland, it promotes sustained increases in plasma growth hormone and IGF-1 levels, which play critical roles in muscle growth, metabolism, and tissue repair. Unlike synthetic peptides, MK-677 is orally bioavailable and has a long half-life, making it a valuable compound for research into growth hormone deficiency, muscle wasting, osteoporosis, and metabolic disorders.

Clinical and preclinical studies have demonstrated MK-677’s ability to increase lean body mass, improve bone mineral density, enhance sleep quality, and potentially offer anti-aging benefits. Its unique mechanism of action allows for increased growth hormone release without elevating cortisol, reducing stress-related side effects.
