What's in deer antler velvet product, what substances or chemicals does it contain?
Velvet deer antler is named after the soft, velvet-like covering that deer antlers have before they turn bony. Antlers are organs of bone which regenerate each year from the heads of male deer. In addition to bone, support tissues such as nerves also regenerate. Nerves grow up to 1 cm each day. Deer antler velvet contains many substances including amino acids, minerals, proteins, anti-inflammatory peptides, hormones, gangliosides and glycosaminoglycans, and Insulin-like Growth Factor-1, IGF1. The composition of velvet supplements depend on the diet of the deer, climate, time of year, age of stag and the various concentrations of substances in different regions of the antler velvet itself.

Deer velvet antler is the only mammalian organ which can continuously regenerate.

Aphrodisiac and sexual enhancement
Research studies with deer antler velvet in relation to sexual function are quite limited. A Russian study with pantocrin, an extract from deer antler velvet, showed the extract to stimulate sexual behavior in rodents more than ginseng. Another study showed velvet to have anti-inflammatory properties and potentially helpful in rheumatoid arthritis. No toxic effects have been found when tested in rodents. A study done in Canada did not find it to have muscle strengthening or exercise enhancing potential.

Availability over the counter
Deer antler velvet is sold in a variety of dosages, most commonly 250 mg. Since these products are available from many countries and regions, one can expect variations in composition between different products. I don’t yet have any personal experience with deer antler velvet. Some products may be adulterated.

Rapid Commun Mass Spectrom. 2013. Detection of human insulin-like growth factor-1 in deer antler velvet supplements. Reported incidents of the use of nutritional supplements containing deer antler velvet by athletes has increased significantly in recent years. The supplements have been reported to contain insulin-like growth factor-1 (IGF-1), which is a banned substance included on the World Anti-Doping Agency (WADA) prohibited list. The presence of deer and human IGF-1 was tested in six commercially available supplements. IGF-1 was extracted from the six deer antler velvet supplements. Five deer-specific and five human-specific multiple-reaction monitoring (MRM) transitions for intact IGF-1were measured as well as six deer-specific and seven human-specific MRM transitions for an IGF-1 trypsin peptide. The presence of a pharmaceutical protein, human IGF-1, was confirmed in four commercially available products sold as all natural, nutritional supplements. These methods can be used to screen additional products to further prevent the illegal sale of adulterated supplements.

Athletic performance, exercise, muscle strength
The effects of deer antler velvet extract or powder supplementation on aerobic power, erythropoiesis, and muscular strength and endurance characteristics.
Int J Sport Nutr Exerc Metabolism. 2003.
Active males were randomly assigned in a double-blind fashion to either deer antler velvet extract, powder, or placebo groups. Subjects were tested prior to beginning supplementation and a 10-week strength program, and immediately post-training. All 38 subjects were measured for circulating levels of testosterone, insulin-like growth factor, erythropoietin, red cell mass, plasma volume, and total blood volume. Additionally, muscular strength, endurance, and VO2max were determined. All groups improved 6 RM strength equivalently, but there was a greater increase in isokinetic knee extensor strength and endurance in the powder compared to placebo group. There were no endocrine, red cell mass or VO2max changes in any group. These findings do not support a red blood cell forming or aerobic ergogenic effect of deer antler velvet.

Safety of deer antler velvet, side effects, risk, danger
Little human research is available regarding the safety and side effects of this natural sexual enhancer.

Do you have any information about side effects associated with taking the growth factors in deer antler extract?
    A. At this time we have not seen human research regarding deer antler extract side effects, but as with most sex herbs, we suggest using a small amount.

Content of testosterone and estrogen
Q. There are many many sites and resources out there which claim deer antler and also elk antler boost testosterone. Nearly all of these resources claim the antler contains many great ingredients including amino acids. Many claim it contains IGF-1 hormones. Some claim it actually contains actual testosterone. I'm boosting my T naturally as it was borderline hypogonodal. I recently purchased some deer antler supplement, well the recommended one, planetary formulas full spectrum antler. Do you know if antler contains testosterone? I'm ok with it if it does. In fact I'm thinking of getting some pine pollen also if the herbs i have don't work as well as I need them too. Also, does the full spectrum antler contain elk or deer antler? Or both? And what's the difference. I've also heard elk is the best for boosting T levels.
    A. As far as we know, the Planetary Formulas is a deer antler velvet product. Here is a study that shows that T is found in this aphrodisiac product.

Testosterone and estradiol concentrations in serum, velvet skin, and growing antler bone of male white-tailed deer.
J Exp Zool A Comp Exp Biology. 2005.
The growth and mineralization of antlers correlate with the seasonal variation of serum androgens. Whereas seasonal levels of testosterone (T) in plasma are well established, steroid concentrations have not yet been determined in the tissues of growing antlers. Blood and antler tissues of white-tailed deer (Odocoileus virginianus) were collected from May to August. Concentrations of T in serum were higher than T values in the velvet and in the antler bone. Estradiol concentrations differed among antler tissues and serum and between years. Estradiol concentrations in serum were consistently lower than those in antler bone and velvet. It is concluded that higher T and lower E2 concentrations found in plasma, as compared to antler bone or antler velvet, may indicate a partial metabolism of systemic androgens into estrogens in the tissues of growing antlers.

Review article
New Zealand Med J. 2012. Health benefits of deer and elk velvet antler supplements: a systematic review of randomised controlled studies. The aim of this systematic review was to evaluate the evidence from RCTs of velvet antler supplements for any condition, using the QUOROM statement as a guiding framework. Seven RCTs were identified as satisfying all inclusion criteria and examined the effectiveness of velvet antler for rheumatoid arthritis (2), osteoarthritis (1), sexual function (1), and sporting performance enhancement (3). Two RCTs reported some positive effects of velvet antler supplements, but neither were convincing while the remaining five RCTs found no effect. Claims made for velvet antler supplements do not appear to be based upon rigorous research from human trials, although for osteoarthritis the findings may have some promise.

Elk antler velvet in dogs for arthritis
Clinical evaluation of a powder of quality elk velvet antler for the treatment of osteoarthrosis in dogs.
Can Veterinary Journal. 2004.
A powder of quality elk velvet antler was evaluated on client-owned dogs with osteoarthrosis in a clinical, double-blind, and placebo-controlled study. Thirteen dogs received a placebo for 30 days and then elk velvet antler for 60 days. Twenty-five other dogs received elk velvet antler for 60 days. On placebo, the 13 dogs did not show significant improvement; however, their gait, their performances in daily life activities, and their vitality were significantly improved with the natural medicine. The 25 dogs on elk velvet antler for 60 days showed similar improvements. No clinical changes were revealed on blood analyses. Administration was effective in alleviating the condition in arthritic dogs.

Elk antler velvet not of benefit in rheumatoid arthritis
A randomized clinical trial of elk velvet antler in rheumatoid arthritis.
Biol Res Nursing. 2008.
This article examines the effects of elk velvet antler on joint pain and swelling, patient/physician global assessment of disease activity, functional ability, quality of life, blood levels of C-reactive protein, and adverse events in persons with stage 2 to 3 rheumatoid arthritis experiencing residual symptoms after standard treatment. Patients were enrolled in a 6-month randomized, triple-blind, placebo-controlled clinical trial. The pattern of change of the measures across time points was essentially the same for both groups. Although some patients reported clinical improvements in their symptoms, there were no statistically significant differences between groups. Overall, elk velvet antler does not effectively manage residual symptoms in patients with rheumatoid arthritis.
