HGH will not make a 60 year old look 45, impossible. Never going to happen. Anyone who says that is full of s hit. If you take no more than 4iu of HGH a day, you won't need anything else. You'll need to be on it 6 months for it to have any benefits, but you won't see or feel anything different.
It helps repair tissue, bones (if broken) and can help with your skin, but that's very, very minimal. As I said in other posts, there are a lot of peptide junkies out there that build their lives around peptides, but the gains are all in their head. A lot of body builders will take more than 4ius a day, but that would require additional insulin and IGF-1, then you start playing with the risk of diabetes. I've used HGH for a number of years and I do it when I feel my joints, tendons and ligaments need help, or like last time, I broke a leg and wanted to help the recovery. But you will not get stronger, will not look any younger but will spend a ton of money on HGH. How do you know if it's real? You don't, unless you send it out to a lab for testing.
