Deer antler velvet is essentially a growth hormone called "insulin-like growth factor 1," or IGF Growth hormones, which are naturally produced by the brain and liver, regulate how our bodies grow. If the body doesn't produce enough growth hormones, dwarfism can occur; too much, and a person may get acromelagy, a type of gigantism. See a human-body interactive. Doctors give growth hormones to young people with stunted growth, but they don't recommend it for athletes or bodybuilders, according to Spyros Mezitis, an endocrinologist at Lenox Hill Hospital in New York City.
That's because many athletes take several times the recommended dosage, which can result in adverse effects, Mezitis said. For example, too much IGF-1 may cause tendons to become too tight and break or may disrupt how the body metabolizes fats and sugars.
A recent study found that taking IGF-1 supplements is linked to improving cartilage damage in joints due to repetitive trauma, Popovitz said. Even so, such studies are still very preliminary, and growth hormone research is still unproven, he cautioned. At the moment, deer antler velvet is available as an unregulated supplement.
IGF-1 affects how the body repairs itself. First, the hormone aids in building up a matrix or base—essentially a building block of protein—that's needed for cells to grow. Then, the substance increases the number of new cells that accumulate on that base, which get busy healing the injury. IGF-1 has shown promise for helping kids with stunted growth or people with dwarfism, as well as for healing cartilage or tendon injuries.
It should not be used without a doctor's care, especially as a performance enhancer. But as far as linebacker Lewis goes, since he's "looking to improve his recovery, I don't think he's necessarily doing anything wrong," noted Popovitz.

Reports claim deer antler helped Ray Lewis overcome his recent triceps tear, and Vijay Singh has admitted to using a spray supplement. First, the facts: Deer antler has been a popular element of Eastern medicine for centuries. And—like red meat, eggs, or milk—deer antler contains small amounts of insulin-like growth factor 1, or IGF-1, explains Oliver Catlin, president of the Banned Substances Control Group BSCG , which tests dietary supplements for illegal performance enhancers.
What forms are those? Nutronics says it has a special formula that penetrates the mucous membrane in the mouth and delivers the chemical directly into the bloodstream within minutes by bypassing the digestive system and liver.
Nutronics lists papers and books written by Alex Duarte on its website, not all of which have been peer-reviewed and most are decades old. A search of academic papers shows newer studies that don't show a statistically significant effect of orally ingested deer antler extract capsules.
And remember that libido comment? A study of 32 men found that there were no significant changes in hormones or the sexual behavior of the men taking deer velvet capsules compared with the men taking placebo capsules Lentini argues that his spray works differently than pills, which are destroyed by stomach acids. Lentini says his business was hit hard when, in , the MLB placed deer antler spray on its list of cautionary products.
This is partly because it contained IGF-1, and partly because it was causing players to test positive for the banned steroid methyltestosterone, although this is not an ingredient in the spray. WADA's new stance on deer antler spray has rolled back the tide, which in turn has been a great boon for manufacturers. For you.
