i was a nutrition major, a lifter and worked as a trainer in gyms for 10 years…
if he’s bent on taking a suplement… have one protein supplement (shake or whatever) a day an hour after you workout. i always got the best results with real food. a can of tuna or chicken breast has about the same protein as a store bought shake at about half the cost.
the real way to get big, in my experience, is to haul your rear into the gym on a REGULAR schedule of lifting set up by a trainer. buying him, or havng him buy 5 sessions with a trainer will benefit him 1000000 times more than a can of protein powder. if he’s just a kid, his metabolism is on fire and more than likely a good lifting regime combined with a GREAT cardio regime will have him eating like a bull. so his best bet moneywise is to chip in to have mom buy some extra chicken and good quality protein foods… have a good, certified trainer give him 5 or 6 sessions to get started and become a regular in the gym.
getting in great shape takes much work. nutrition isn’t going to do ANYTHING to build muscle if he’s not doing the work in the gym.
it might start as vanity, but i don’t have a problem with that… looking good is not a bad thing. and if he learns and maintains healthy eating and exercise habits… he may be adding dozens of years onto his life.
muscle isn’t hard to get. give a chimpanzee a weight and a consistent schedule… he’ll get strong. thats the key. consistency. consistency in the gym overcomes many errors in a diet.
weightlifters and bodybuilders are some of the MOST disciplined people you will ever meet.
creatine is probably the most widely used supplement… it works to improve muscle output and is completely safe… tested by science and in the gyms for decades…
of course, as i got older… the only supplement i favor now is the one sitting next to me… Sam Adams Octoberfest.
