Vitamin Shoppe if you have one near you offers inexpensive sample packs for purchase. Prior to my trip to Chicago, I bought some protein and staples instead of bagging and explaining my sh1t to airport security.
Other options. Search "Supplement Samples" It's how I discovered "EAT THE BEAR" Protein. Solid! Protein there.
If I were a rep, I'd get you some stuff.

Amazing Pre with MaxReps + (Its going to be re-released, had clumping issues, but I tried to tell them the gainz were locked into the clumps...)
Modern Pre is pretty good but doesn't compare to MaxReps +
