I never take a product without doing my research, because it is always good to know what you're putting in your body. I looked at several sources including scholarly journals about many of the ingredients in Deer Antler IGF-1. It is a great product, and has been proven to work without ANY side effects. This product has definitely been helping with my lean muscle gains during my improvement season. It gives me energy before a workout, and it gives me some great vascularity while I'm lifting!

In another randomized, double blind, placebo controlled experiment (Broeder, 2004), 38 males, all of whom were experienced weightlifters, entered a 10 week strength training program. Those who took deer antler velvet experienced an increase in peak torque and average power relative to the placebo group. They also experienced unexpected improvements in aerobic performance.
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.
