Sides: Very little. It sucks injecting yourself 2 times daily for 6 months, but worth it. Small joint pain that would last in one location (knuckle, knee, elbow) for roughly 2 days and then be gone. It was very mild. I also feel like my gym shoes are a little tighter than they used to be (literal growth in feet?). I also had a decent amount of water retention, especially in my face making it look like I had bags under my eyes, and overall moon face that went away within a couple weeks after the cycle ended. Biggest side effect: naysayers. I made the mistake of telling my good friend that I started with HGH. Since his wife has essentially castrated him, striped him of his masculinity, and has rendered him as an unemployed house husband, his wifey pillow talk manifests into lectures from her, through him, and eventually to me. "Yeah I looked up side effects and this guy on a video, I don't know who he is, but he says it can make your organs grow." Yeah, he might be talking about this beautiful bitch right here, however to have your organs grow, you need far more than 6 daily iu's for 6 months. Rich Piana discusses his long term use of HGH, and he's admittedly done it for straight 10 years. Even in one of his videos, he said he was injecting 2 iu's every 2 hours for several months for an upcoming competition. Organ growth from HGH takes years, with a large amount HGH being administered. So good luck affording it. My friend's concern of growing organs is like saying that you'll end up with cirrhosis of the liver after a weekend of moderate drinking.
