No. IGF-1 LR3 is not an approved medicine in the United States. Its legal category is "Not approved; research use only". Nothing that contains it is allowed for any use in people. Vials labeled "for research use only" get no exception: that label does not make them legal to use in people. On the evidence, no completed trial in people is cited on its profile (1 human record with no result or no dose given).

The full Canada answerIGF-1 LR3 in sport and the military
Whether IGF-1 LR3 is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status. Before you compete or get tested, look up IGF-1 LR3 by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
