While Lentini admits sales have picked up, he says he's been hurt by the perception in the recent baseball letter, which told players that deer antler velvet could be contaminated with methyltestosterone, a banned steroid. The connection is based on the fact that David Vobora tested positive for the steroid after using antler spray. He won a $5.4 million judgment against the company that made the spray.
Performance - Borrowing the scientific research, its mandatory use by the Soviets has shown increased blood circulatory benefits, liver protective attributes and nerve strengthening effects of the aqueous alcohol extract.* This means it increases nervous innervation, easily known as the contractile capacity of muscle groups.* This leads to short burst style athletic performance increases found in weightlifting, bodybuilding, and similar sports.*

I know of no scientific evidence to support any of the marketing claims made for these supplements. I discussed your question with Tieraona Low Dog, M.D., an internationally recognized expert in the fields of integrative medicine, dietary supplements and women’s health, and an authority on botanical medicine. She explains that IGF-1 in the velvet promotes rapid growth of the antler. Dr. Low Dog notes that the two studies examining the effects of deer antler velvet supplements taken by athletes have yielded conflicting results. One showed some improvements in endurance and knee strength in weightlifters, but the other found no differences in rowers after 10 weeks of supplementation.
Even sellers of deer antler products doubt that the products could deliver IGF-1. "IGF-1 is very unstable," Dean Nieves of Florida-based Bio Lab Naturals told the Baltimore Sun. "It could not exist outside of a very controlled environment." Nieves' company therefore markets the product as a nutritional supplement. "It is just packed with nutrients," he said.
Unfortunately, the potential problems with IGF would seem to negate any of these theoretical benefits.  It has been shown that improper use of hormones such as dehydroepiandrosterone (DHEA), androstenedione, and human growth hormone may increase the risk for development of prostate cancer or promote the growth of existing prostate cancer by raising IGF-1 levels.  Therefore, men who are taking supplements with IGF in it (or those that raise IGF levels) could theoretically be putting themselves at an increased risk for prostate cancer.  Again, it hasn’t been rigorously studied so it’s impossible to know for sure, but if you have any risk factors for prostate cancer, it’s probably best to avoid taking this supplement.  
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.
Joint Health & Injury Recovery* - Due to certain constituents recognized by the government one will benefit by better joint health, plus the content of proteins similar to our own bodily structures are plentiful within deer antler supplements, such as type II collagen.* Another involved and interesting cellular activator known as hyaluronic acid has many additional benefits for repair and regeneration.

"I am 60 years old and had polio when I was six months old. Throughout my childhood I had 7 orthopedic surgeries to correct the damage leftover by polio to my left hip, leg and foot. I am battle scarred and a Post Polio Syndrome Survivor. I cannot praise your product enough! Its difficult for me to walk. I normally use a battery powered scooter in malls and airports. The least amount of physical exertion walking and standing creates days of agony afterwards. This past Saturday I walked the mall, went for a movie and dinner. I was active all day and well into the night without tiring. I kept waiting for the intense painful spasms and muscle contractions from my polio atrophied muscles in the left leg and also my hips. Usually late at night is when the pain and spasms are the most intense. But guess what? I am not hurting anywhere near the level I use too. I am not fatigued. I used Antler Farm's Deer Antler Velvet a couple of years ago when traveling to Machu Picchu, Peru. I am still amazed I climbed the ancient Inca Trail unaided with just my cane. Antler Farm's Deer Antler Velvet has improved my quality of life significantly."*

Chondroitin sulfate is a compound of connective tissues that are usually found in cartilage. Glucosamine sulfate is a natural building block for the growth and maintenance of healthy cartilage. Since osteoarthritis is caused by the deterioration of the cartilage in the bone joints, a daily supplement of deer antler velvet can help to stimulate the repair of deteriorated bone cartilage with healthy doses of chondroitin sulfate and glucosamine sulfate.
I am a 52 years old from New York City. I have been taking anti-depressants and sleeping pills for many years. Since my husband and I started taking IGF-1 and the sleep miracle product, I was able to stop the anti-depressants and also thanks to the sleep miracle I am able to get a great nights rest without sleeping pills. Not to mention, both our libidos have been fantastic! WOW! We feel like newly weds again.
In Asia, velvet antler is dried and sold as slices, or as a powder which may be boiled in water, usually with other herbs and ingredients, and consumed as a medicinal soup.[6] In the traditional commercial trade of Korea and China, whole stick antler velvet is divided into three sections based upon their supposed properties. Although there is an absence of uniform standardization, these sections are known as the wax piece (uppers or tips), the blood piece (middles), and the bone piece (bottoms): the wax piece may be marketed as a growth tonic for children, the blood piece supposedly for joint and bone health, and the bone piece supposedly for calcium deficiency and geriatric needs.[2][5][9] Early commercial activity in Russia between the 1930s and 1980s led to the production of an alcohol extract from deer antler velvet marketed under the Russian drug trade name Pantocrin (also pantocrine or pantokrin).[10][11]
