Other studies reported an increase in heart strength and volume of blood pumped, while cardiac output, heart rate, mean arterial pressure, pulse pressure, central venous pressure and other parameters remained unchanged. Researchers suggest that the polysaccharides in antler may reduce the blood’s tendency to clot, improving circulation, decreasing stroke risk and boosting general cardiovascular health. Researchers theorize that the deer antler velvet may improve blood supply to muscles or act as an anti-inflammatory, allowing athletes to recover faster from training sessions.

Immortal Antler Velvet Silver is a less potent form of antler velvet than the Gold. It’s the only all-natural 19:1 extract that contains a powerful blend of growth factors in a naturally occurring matrix, and the only all-natural proprietary matrix to deliver up to 45 mcg’s of IGF-1 per bottle, in addition to the full growth factor matrix. Delivering a full range of growth factors at a 19:1 ratio means it requires 19 lbs of velvet antler tips to create 1 lb of this complete formula. Immortal Antler Velvet Silver is extracted in organic grape alcohol and bottled in miron violet glass for maximum absorption and effectiveness.
"This mountain bike loop that I do almost everyday usually takes 48-50 minutes. After a few weeks of Antler Farms®, I saw that number continually go down. I am at basically an average of 4 minutes shaven off every time that I do that loop. Faster recovery also. I have more energy later on in the afternoon. Just all around really good results. Good stuff. Highly recommend it."*

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.
