charlitos saidWhey protein, glutamine, creatine, they are all good supplements to have, they are all safe and relatively cheap to get. It wont make you a super model overnight but it will help your gradual muscle growth and tone. You should also follow a low fat diet and work out 5 times a week. You should be seeing pretty decent progress within 4 - 6 months.
note: You seem to have a high metabolism so avoid cardio and focus on weight lifting.
Save your money on the whey protein and just eat smartly and timely. Glutamine and Creatine are effective but the latter is not without side effects.
PS A personal metabolic rate cannot be determined by inspection and just because somebody is lean does not mean they have a high metabolic rate.
Let me give a better example. Generally, metabolic rates are higher in the winter than summer but many see a winter weight gain.
It is highly unlikely that he'll gain 50lbs by winter based on seasonal changes alone, it is by far more likely that he just has a high metabolism according to his age, height, weight and body type. So while what youre saying is somewhat possible, it is not really all that accurate.
Whey protein is not a waste of money and I can attest to that. It is almost impossible for me to put on weight due to high metabolism and the fact that I cant eat much on a single serving. Supplementing protein actually helped me gain over 30 pounds to be at where I am now 185lbs. I used to be 195lbs two months ago, I stopped supplementing protein and I lost 10 pounds. It works for some people.
As for Creatine's side effects I want to make clear that Creatine is one of the most-researched sports supplements out there and there's no published literature to suggest it's unsafe.
