Published research context (not product claims)
Long Arg3 IGF-1 is used in literature as an IGF-1 receptor research ligand. The Arg³ substitution and 13-residue N-terminal extension are studied because they change IGF-binding-protein interaction versus native 70-aa IGF-1 in binding and cell-signalling assays.
Those papers are experimental comparisons of receptor occupancy and downstream assay readouts. They are not muscle-growth or height claims for this vial.
IGF-axis peptides are WADA-prohibited in sport. That is an anti-doping listing, not a use instruction.
There is no UK marketing authorisation for this research listing.
