IGF-1 is currently on the World Anti-Doping Agency’s prohibited list due to how it gives athletes an unfair advantage in terms of building strength and muscle mass. (7) However, it’s still legal to use supplements that may provide IGF-1 or similar effects. Most of the studies that show positive results from using deer antler supplements have used high doses. And some have tested the product on animals (mice or rats) rather than humans.
A systemic review on human interventions[25] makes note of a study conducted on patients of osteoarthritis (Edelman et al. 2000; cannot be located online) which found improvements in joint pain symptoms relative to baseline in the Velvet Antler group and not placebo, although a lack of information on blinding and randomization precludes results that can be drawn from this study.
