More efficient than your protein powder and most sources of protein. Aminos go straight to use within 30min because of minimal digestion needed and almost no caloric impact. So again, NOT meant to be a meal replacement but one heck of an addition that has changed the game for me, my energy, & tone. Not medical advice. Always discuss your health concerns/supplements with your doctor. #gymtok #crossfit #antiaging #perfectaminos #fitmomover40
