Thanks for all the info. That is a big help. I am leaning towards the monohydrate tablets. This is because I tried the CE2 from GNC a while back and saw minimal benefits. Thought maybe the monohydrate might work better for me. Or maybe it is just the GNC stuff that is just not all that good.
Monohydrate tabs are kind of expensive considering that it is well... monohydrate (1000g is about $20 in powder). Here are some brands that I just found off another website.
Dymatize: 75g for $9
NOW: 90g for $7.50
Ultimate Nutrition (CreaPure): 180g for $12.80
You get the idea. Obviously, you are going to be paying more per gram - but you already knew that! To see what is going to be the cheapest per gram, simply divide the cost by the number of grams. I don't know if you do it this way already, but a lot of people actually get confused by it, so here's how it works (ignore this if you already know...):
Cost per gram = $$$ per bottle /
total grams per bottle
= $$$ per bottle / [grams per serving * number of servings]
Find a reasonable price per gram, go with a supplier that you trust (I don't suggest the white van across the street), and you'll be set. You can take the caps according to how many grams of creatine you want per serving, so don't go by their amount per serving, which can be misleading.
