Definition

HGH Frag 176-191 is a modified peptide fragment derived from the last 15 amino acids of the full human growth hormone (HGH) sequence. It is designed to selectively study the fat-metabolism effects of GH without activating IGF-1–related growth pathways.

Available Formats

  • 5mg lyophilized peptide

Mechanism of Action

HGH Frag 176-191 interacts with metabolic signaling pathways involved in lipolysis and fat oxidation. Research suggests it may: This selective activity makes it a common tool in metabolic-focused research.

  • Increase fat breakdown in adipose tissue
  • Reduce lipogenesis (new fat storage)
  • Enhance fatty-acid availability for energy
  • Influence energy-balance pathways without elevating IGF-1
  • Act independently from the growth-promoting actions of full GH

Areas of Investigation

HGH Frag 176-191 is commonly studied for

  • Fat-loss and adipose-tissue metabolism
  • Energy-expenditure regulation
  • Lipolytic pathway activation
  • Anti-lipogenic signaling
  • Potential roles in obesity-related models
  • Glucose-handling stability compared to full GH

Safety Profile

Reported findings include: Overall, studies show a favorable profile compared to full GH due to its selective action.

  • Mild injection-site redness
  • Temporary fatigue
  • Increased hunger in some models
  • Occasional lethargy
  • No IGF-1–related systemic effects

Interaction Notes

Commonly studied with: No harmful interactions have been reported in controlled preclinical models.

  • GH secretagogues in metabolic-synergy models
  • Lipolytic-pathway activators
  • Peptides explored for weight-regulation research
