Diverse Biological Activities The peptide's biological activities are remarkably diverse and include stimulation of collagen and glycosaminoglycan synthesis (critical for skin, connective tissue, and wound healing), activation of wound healing mechanisms, promotion of blood vessel formation (angiogenesis) to support tissue repair and regeneration, anti-inflammatory effects that resolve excessive inflammation while supporting beneficial healing responses, antioxidant and protective effects against oxidative damage and toxic compounds, attraction of immune and repair cells to sites of injury, remodeling of extracellular matrix through regulated metalloproteinase activity, stimulation of nerve outgrowth and regeneration, and even modulation of gene expression in patterns that reverse age-related changes and restore more youthful cellular function
The effects on physical performance
Currently, tirzepatide and semaglutide are available through prescription in Canada while Retatrutide remains in clinical trials with FDA approval expected in late 2026 or early 2027
As of mid-October, most of the companies that received warning letters were still advertising retatrutide for sale online, at prices ranging from around $100 to $1,000 per vial
