Trust me if I could get my hands on HGH I would take it. But it illegal in canada and only given to kids with rare growth problems. Also its quite expensive if you can get some.
As for l glutamine yes some people like your self have a reaction to it. Your best bet would be to eat only fruit. For me I only eat 30-40 bananas a day. I have reactions to everything else. I get horrible joint pain.
If you can't eat fruit find something you can eat. IF AND ONLY IF you don't have auto immune reactions like joint pain. Colostrum helps improve your immune system and helps heal leaky gut.
Do not take it if you have a auto immune reaction of any kind because colostrum improves your immune system so much that your auto immune reactions will rage out of control.
