Do not be fooled by companies who make false claims and be aware that there is a difference in deer antler velvet quality and absorption rate. Nutronics Labs only utilizes Grade A New Zealand Deer Antler Velvet extract in its various IGF liposome formulations. Nutronics Labs proprietary blend of Deer Antler Velvet extract in liposome formula carries the highest potency in the world and is free of any contaminants or filler compounds.
A systemic review on human interventions 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.
