Powdered velvet antler is available in capsule form from health shops. As a general tonic and to fight fatigue, the recommended dosage is usually 1 or 2 capsules (250 to 350 milligrams each) per day.

Keeping true to our original Deer Antler Spray formula, Deer Antler Velvet Extract HERS is all-natural and contains the same amount of Deer Antler Velvet as the original, coming to us straight from red deer in New Zealand. Like the original, our new product is high in the growth hormone IGF-1. This new spray, however, is testosterone free and contains: collagen type II, biotin, green tea, and epimedium, all of which have benefits specially geared toward female athletes. Epimedium, known in Chinese medicine as “yin yang huo”, has the same effect as estrogen, can increase libido, and produce osteoblasts, the cells that secretes the matrix for bone formation. This promotes strong bones, and aids in the prevention of osteoporosis. Collagen, is a protein that forms the strong, flexible white fibers of the body's bone, cartilage, and connective tissue, and is vital for tissue regeneration. Biotin can speed up metabolism, improve glucose levels, and improve brittle nails. Green tea, is one of nature's most powerful antioxidants, and has been linked to cancer prevention, Alzheimer's prevention, the prevention of obesity, and countless other health benefits.
In September, 2013, the headquarters of S.W.A.T.S. was raided and ordered to be shut down by Alabama's attorney general citing "numerous serious and willful violations of Alabama’s deceptive trade practices act". Among the violations were "claims that the company made about a number of products that were unsupported by scientific research. Some of these products were marketed as 'dietary supplements.'"  The assistant Alabama attorney general "says that Deer Antler Spray is dangerous and its sellers are law-breakers." 
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).
Deer antler velvet's effects on cell growth and repair have been investigated in several areas.
