Shipping Supplements in Car

I am preparing to ship my supplements in my car to where I am attending graduate school. I am using an auto shipper and the whole shipping process is to last no longer than 2 weeks from when I drop it off. Should I ship my various protein powders and supplements? What is ok to send and what is not? Obviously, I am not going to send my balance bars, but will the heat screw up the powders?
Thanks,
Riley

I shipped a car from Europe & had everything stolen that was not bolted down…just a heads up

I shipped a car from Texas to California and 12 days turned into 42.
