ZMA =: Bullshit. A good Magnesium supplement should be a staple supplement though (along with fish oil and vitamin D)
Kre-Alkalyn = bullshit. Use monohydrate.
Nitrix supplements = bullshit
Halo = overpriced bullshit. Find a simpler one with similar ingredients. Universal Torrent is the one I use.
Don't take fat in your PWO, or your insulin is pushing fat rather than aminos into your cells.
So if you're going to mooch of your brother get:
Magnesium (something chelated - it will end in "ate" like "Magnesium Malate") take enough to get 300-400mg per night. Take it at night, it has a nice side effect of helping you sleep.
Vitamin D - absolutely crucial if you live in Vancouver where the sun shines about 2 months a year. 1000 iu should be enough in the summer if you're outdoors a lot and get a lot of sunshine. Otherwise take 4000-5000 per day.
Fish Oil - Get a concentrated supplement. The best is bottled (usually just tastes like lemon) Ascenta has a very good quality fish oil for a good price. 1 tbsp per day
Then you have the workout stuff:
Creatine Monohydrate 5g per day (take with PWO on workout days if it's not already in the PWO)
Protein powders - whatever you like, just don't get "gainer" supplements
PWO - like I mentioned above.
That will be more than enough. Just focus on working hard and eating. Just about everything else is silly BS.
