I just got a free same of this thing called "spike". I saw it in a magazine or something and had them send me a sample. That was back in like April. It came today. I'll try one or two. I doubt it'll kill me.

I also got today, a free sample of Nitrean protein from AtLarge Nutrition. Sorry it's a secret how I got it, but it is a sizable sample; probably about two pounds: one chocolate and one vanilla. I will post a review after I try it. It's got a mix of whey isolate, casein and egg proteins.
And, actually the other day, I got a free sample of Muscletech's CEE-Pro. It's a secret how I got that one too.
Can't spoil my sources, or else I won't get anything else from them!
