Anti-Aging Support: Formulated with eight types of peptides and growth factors (GF) to promote skin regeneration, healing, and improved elasticity

Recombinant Human IGF-I LR3 is a 9.1 kDa, single, non-glycosylated polypeptide chain containing 83 amino acid residues.

In contrast, modified NADs typically require carriers to enter target cells and reach specific intracellular locations

It was characterized in the literature as the first selective growth hormone secretagogue

Interest in these peptides often comes from experimental findings linking them to signaling pathways involved in angiogenesis, cytoskeletal organization, and extracellular matrix remodeling
