An acute dose of 2,000mg/kg Deer Velvet Antler to rats (human equivalent dose of 320mg/kg) has failed to show toxic signs over 14 subsequent days of observation, and a 90 day trial with daily dosing of 1,000mg/kg did not show any significant toxicological symptoms of haemotological signs; a decrease in liver weight was noted in males, but under histological examination it appeared to be benign. Another rat toxicological study using 10% of the diet as Deer Velvet Antler during gestation and after birth noted that there were no apparent teratogenic effects on the rat pups and that serum AST (indicative of liver damage) was actually decreased 50% relative to control with no effect on γ-GT (another liver enzyme).
A systemic review on human interventions 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.
One of the leading companies in the world that manufacturers deer antler spray is called Nutronics Labs. According to information posted on their website, they have been making deer antler supplements for two decades. They state that their deer antler products range in concentration/strength from about 25,000ng (nanograms)–200,000ng of IGF-1. According to studies done by Nutronics Labs, deer antler powders appear to be less concentrated with IGF-1. They also may be poorly absorbed compared to deer antler extract.
There is an increasing amount of scientific evidence supporting the benefits of deer antler velvet from decades of research carried out in Russia, Korea, China, Japan, Australia and New Zealand. This research has given credibility to deer antler velvet’s traditional usage and validated recommendations for its inclusion as an everyday health supplement. Almost 250 papers have been published since 1930 on the manufacture, composition and biochemical effect of deer antler velvet. Studies on deer antler velvet and the corresponding findings are described below.
Nutronics Labs Maximum is one of the most effective Antler Velvet products on the market. With our 100,000 Nanograms of IGF-1, IGF-2 & other growth factors from the World's Purest Deer Antler Velvet, Maximum can help anyone train harder, build lean muscle or speed their recovery time. Maximum is also for anyone who wants to achieve optimum IGF levels.
We know about growth factors, such as IGF-1, which are responsible for promoting healthy hormones. It is the synergy of all the constituents that help these growth factors work better. And this is why our deer antler velvet is so awesome! If you go read other labels and check the magic "extract-ratios" and micro-nanogram amounts, you'll discover something interesting:
My name is Michael Morabe and I’ve been an avid and addict of sand and indoor volleyball. I’m 27 years old and after getting back into volleyball 2 years ago, I realized I needed to lose weight. I just played more and more, shedding weight pretty rapidly, but after I lost about 35-40 pounds, I couldn’t do much more without starting to diet. The added problem was my recovery after playing so much during a week whether it be pick up or tournaments.
I never take a product without doing my research, because it is always good to know what you're putting in your body. I looked at several sources including scholarly journals about many of the ingredients in Deer Antler IGF-1. It is a great product, and has been proven to work without ANY side effects. This product has definitely been helping with my lean muscle gains during my improvement season. It gives me energy before a workout, and it gives me some great vascularity while I'm lifting!
In rats undergoing left coronary artery ligation, those with heart failure were given either Velvet Antler (Deer) or Captopril as active control for 4 weeks with a third group given water. No significant changes in cardiac structure was noted with either Velvet Antlers or Captopril (with the heart tissue being enlarged after heart failure) although left ventricular ejection fraction (LVEF) and fractional shortening (LVFS) appeared to be improved in both treatment groups to approximately the same degree and the increase in serum Brain Natiuretic Peptide (BNP) that occurred with heart failure was attenuated the same degree in both interventions.
When antlers fall off, they leave wounds that heal quickly, without forming a scar. Researchers have found that velvet antler contains substances that encourage healing, and could be of use to humans. Of particular interest are 3 hormones known to promote growth of skin tissue: insulin-like growth factor (IGF-1), epidermal growth factor (EGF) and transforming growth factor-β1 (TGF-β1). In a recent study, an ointment made from velvet antler, containing these compounds, enhanced healing when applied to the skin of rats. IGF-1 was a hot topic in the media in the winter of 2013 when a football player, Ray Lewis, was accused of using a banned spray containing IGF-1.
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.
