he Retatrutide / Follistatin 344 Blend Pen combines two advanced peptides within a convenient ready-to-use injectable format designed for clinic-led body composition and performance-focused programmes. Retatrutide is recognised for its broad metabolic support across GLP-1, GIP, and glucagon receptor pathways, helping support appetite regulation, metabolic efficiency, and sustained fat loss. Follistatin 344 is widely studied for its role in regulating myostatin activity, supporting lean muscle development and recovery performance. Together, this advanced blend is increasingly incorporated into high-level optimisation protocols aimed at supporting both fat reduction and lean muscle preservation or development simultaneously. The combination is particularly suited to clinic-led transformation, longevity, and advanced physique optimisation programmes where comprehensive body composition support is required. The injectable pen format provides simplified administration and consistent dosing for professional treatment environments.
