Muscle building Peptides for men

Updated: Jun 22, 2023

There have been many clinical studies examining the effects of peptides on muscle building in men. Peptides are short chains of amino acids that can potentially enhance muscle growth and recovery.


One of the most widely studied peptides is known as "growth hormone-releasing peptide 2" (GHRP-2). In a 2011 study published in the Journal of Endocrinology, researchers found that GHRP-2 increased muscle mass and improved muscle strength in healthy young men.

Another study published in the American Journal of Physiology in 2012 found that a peptide called "beta-alanine" improved muscle endurance and reduced muscle fatigue in male subjects.

In a 2013 study published in the Journal of Applied Physiology, researchers examined the effects of a peptide known as "IGF-1" on muscle protein synthesis in healthy young men. The study found that IGF-1 increased muscle protein synthesis and improved muscle strength.

MK-677 is a peptide that is commonly referred to as "Ibutamoren" and it has been studied for its potential to increase growth hormone levels in the body, which may lead to muscle growth, improved bone density, and other benefits. Here are some clinical studies that have investigated the effects of MK-677:

  • In a 1998 study published in the Journal of Clinical Endocrinology and Metabolism, researchers found that MK-677 increased levels of growth hormone and insulin-like growth factor-1 (IGF-1) in healthy men and women. This study suggested that MK-677 could be used to treat age-related growth hormone deficiency.

  • In a 2009 study published in the Journal of Gerontology, researchers found that MK-677 improved body composition and increased muscle mass in elderly men and women. The study also found that MK-677 increased bone mineral density in the hip and spine.

  • A 2011 study published in the Journal of Bone and Mineral Research found that MK-677 increased bone turnover and bone mineral density in healthy older men and women. The study suggested that MK-677 could be used to treat osteoporosis.

  • In a 2018 study published in the Journal of Clinical Endocrinology and Metabolism, researchers found that MK-677 increased lean body mass and decreased fat mass in healthy men. The study also found that MK-677 improved insulin sensitivity and glucose metabolism.

While these studies suggest that MK-677 may have potential benefits for muscle building and other health outcomes, more research is needed to fully understand its effects and potential risks. It's important to consult with a healthcare professional before beginning any new supplement regimen. You can contact us at DrBarx.com to discuss HGH and muscle building peptides.
