In people

After one injection, growth hormone rises 2 to 10 times and stays up for six days or more, and IGF-1 rises 1.5 to 3 times and stays up for 9 to 11 days. With weekly doses the levels build and hold. People report fuller sleep, faster recovery and firmer skin by the second or third week. Some notice water in the hands, tingling or a flush on injection day, all signs of a strong growth hormone signal. Over two to three months lean mass rises and belly fat falls.
