Im 17 years old, i have been lifting all throughout highschool religiously for sports, etc and i have been taking a whey protien powder and mixing in a few grams of creatine as a postworout shake and maybe just the protien powder at night. I was usingamino acid complex for a while, but that got kindof expensive. thats the extent of my supplement usage. I was wondering if i could add to the mix before bed and if that would be safe for someone my age. Im also thinking about dropping the creatine and starting up the animal nitro again instead of the creatine. any comments are greatly appreciated.
