I bought a couple of tubs of generic weight gainer off of Craigslist last week for $30. The retail price was $65 for just the larger tub, and I thought I was getting a killer deal. I didn't even think of checking for an expiration date on it.
When I opened the tubs, they were so packed down that they were a solid chunk of chalk. I'm drinking a shake from that batch now, and it's obviously stale. Should I drink it up anyway?
