I would like to express my deepest gratitude for IGF-1. I am 54 years old and until now I have suffered with chronic fatigue, depression and insomnia. After being on IGF-1 for less than 1 month, my energy levels are back up and improving more everyday. I once took 3 naps per day just to function, I do not need naps anymore. I once needed prescription sleeps aids, now I sleep all night long without medication, thanks to IGF-1. It is hard to put into words all that IGF-1 is doing for me, so I will just say I feel like a new man with vitality that I have not felt in 25 years.

The appropriate dose of deer velvet depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for deer velvet. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
One study (duplicated in Medline) that used a water extract of Velvet Antler at 50-200mg/kg failed to inhibit the pain killing effect of Morphine yet reduced the rate at which rats became tolerant to Morphine over the course of 6 days when taken an hour prior to Morphine each day. Rats who were given Velvet Antler prior to Morphine also experienced 26.6-36.6% less withdrawal (dose-dependent) and reduced reverse tolerance and dopamine receptor supersensitivity relative to morphine control.
1g of Velvet Antler taken daily for 12 weeks in otherwise healthy adult men has failed to significantly alter serum testosterone levels, either total or free testosterone. Another study in otherwise healthy men has also failed to find such an effect on the endocrine profile, with 11 weeks of 1.5g supplementation failing to alter serum testosterone and a lack of effects also noted after 10 weeks of 560mg in males and females who performed a consistent rowing regimen.
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.
