Maybe it was the sugar in the GNC crap that caused elevated blood glucose levels, leading to arterial damage leading to your own liver producing more cholesterol to repair the damage? Did you gain or lose bodyfat during this experiment? (affects insulin sensitivtiy) Did you gain or lose bodyweight during this experiment? (affects insulin sensitivity) Did the seasons/your seasonal sun exposure (affecting the hormone vitamin D) change during these few months? What other life factors changed during this experiment? All of these things would cause physiological changes to your body that could elevate cholesterol levels.

Dietery cholesterol means nothing, it's pretty much proven.
And your total cholesterol means even less. You should only be worried about your HDL being low, if it's not high enough, then get worried.
