Sourced from New Zealand, Piping Rock’s IGF-1+ extra strength Deer Antler Velvet Spray taps into ancient practices famously exploring male virility.** Each spray contains the beneficial amino acids, peptides, proteins and insulin-like growth factor-1 (IGF-1+) naturally found in deer velvet, making this spray a popular choice among athletes, fitness enthusiasts and those who are looking to support muscle strength, stamina, vitality and overall male performance.**

The harvesting of deer antler velvet can be a painful process, as the velvet tissue contains an abundance of nerves and bleeds profusely if cut or removed. Dr. Low Dog says she has no problem with harvesting velvet from deer killed for food, but is concerned that shortcuts will be taken should demand for the supplements continue to grow. She notes that the United Kingdom has banned the removal of deer antler velvet under its welfare-of-livestock regulations, unless the antlers have been damaged or most of the velvet has been shed.

Published research has shown that IGF-1 can produce similar results to growth hormone. The catch? If you do the math from the study, a 150-pound man (that’s a pretty small guy, so a bigger man would need more) would have to take more than 25 million nanograms just to experience the growth hormone-like effects of more muscle, less fat, and faster recovery.
Deer antler velvet is rich in insulin-like growth factor 1 (IGF-1) which is a growth hormone produced naturally in the liver as a response to human growth hormone (HGH) stimulation. This is a key factor in how deer antler velvet can help to promote muscle growth. IGF-1 works on the body by promoting the growth of healthy, lean skeletal muscles. This growth of healthy muscle mass can be influenced by IGF-1's tendency to increase muscle protein and muscle DNA content. There is evidence to suggest that IGF-1 acts on muscle tissue by promoting protein synthesis and the proliferation of satellite cells, both of which result in skeletal muscle growth due to the enlargement of the muscle cells.

The FDA considers deer antler spray (or deer antler velvet) to be a dietary supplement. This means it doesn’t need to be extensively studied and regulated like medications. For this reason, it can be hard to tell what the actual concentration of active ingredients or IGF-1 is in various supplements. Plus products can differ quite a bit from one brand to another in terms of their purity and effectiveness.
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.
