Hi.I'm here to enquire about protein powder. Erm I am a 16 years old teen , is it appropriate for me to consume protein powder? I had hitting the gym for 6 months and plus , there is some muscle gain for me but slightly noticeable. So I would like to consume protein powder, will it help me to gain muscle? I go to the gym 3 days per week. and I'm Asian , and I would like to know which protein powder is the best, i mean less negative effects and effective for muscle building for teens, regardless the price. thanks.
