The chairman of the Olympic Committee mandated all athletes use their patented deer antler extract to increase recovery, growth and performance. Don't you remember the Soviet who dominated Rocky? And to those who know their history, the Soviets did actually dominated Olympic sports, especially weightlifting, from the early 70's to the late 80's. Could this have been a secret confidential edge?
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.

Deer antler products contain mostly amino acids (that form proteins) along with growth factors, which are poly-peptide bonded amino acid chains. (4) The most abundant growth factor is IGF-1. However, it isn’t a factor found in these products. Depending on the specific brand, deer antler spray/powder/capsules may contain amino acids and growth factors including: (5)
Velvet antler is the whole cartilaginous antler in a precalcified growth stage of the Cervidae family including the species of deer, elk, moose and caribou. Velvet antler is covered in a hairy, velvet-like "skin" known as velvet and its tines are rounded, because the antler has not calcified or finished developing. Velvet antler preparations are sold in China as part of Traditional Chinese medicine, and in the United States and some other countries as a dietary supplement.
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]
