I know there are sites you can subscribe to that will send you muscle-building, nutrition samples, fitness samples, creatine samples, pre-workout samples and so on. I've tried tigerfitness but i got burned by their shipping cost. I think that suppsamples.com charge also. There's something called sixpacksack.com and they send samples in a sack each month to your house. I think they are just starting but I was wondering if anyone has used that site before.
