The price fluctuates greatly. In areas where there is a heavy gay concentration (meaning AIDS cases and hip HIV doctors perscribing GH and juice) the market is glutted and the price dips below $350. (One guy said he was getting them for $275.) In areas where doctors don't write script for GH (and insurance doesn't cover it) $700 is a good price.
Years ago I was buying kits to send to a friend back east. He was thrilled that we could get kits for $900. They sold for $1500 in his gym.
I asked a friend in West Hollywood about GH prices. He is the biggest GH slut I know. He said the real bargain is on expired kits with no hologram... problem is obviously they are EXPIRED and no hologram raises the risk of fakes.
