energy

Do you think there are any products for pre workouts that are light? I'm only 21 years old and I only weigh 125 lb. some of my friends take a lot of pre workouts and take energy drinks before we go train. My issue is I want to get some energy as well but I don't want to take something 2 strong

I am a 45 year old man and I'm definitely hitting a midlife situation where my energy levels are starting to drop and I'm feeling like it's becoming a chore just to get in the weight room. I think I might be deficient in a lot of vitamins what is the best product I can use to get me feeling good...
