I am 21 years old and I'd say I'm at the intermediate level in my workouts. I work out 4 days a week taking off wednesday and the weekends. I'm looking to put on a little bit of muscle mass but I dont want to get fat. I'm currently taking Afterglow, I dont know if you guys are familiar with it. My question is, should I be adding l-glutamine to it or not? I have been and I'm not sure if its going to help or hurt me. Another question is, is it safe to be mixing creatine, l-glutamine, and the afterglow all together. I just started taking creatine monohydrate today and I took 10 grams in my shake after my workout and felt a little sick, feeling better now though. Any tips or pointers would be greatly appreciated.
