Bests & Worsts Reviews from Amazon

I like ON Amino Energy but I have an issue with the Amazon bought product: I originally purchased this product from Costco, and liked it for the pre-workout. Next batch I decided to purchase from Amazon. It should have been exactly the same except a different flavor. However, this batch was somehow different in a bad way. First, right out of the package, the lid wa halfway open, even though the seal was still on. Then, I noticed that I didn’t get the same energy as before. Not only that there was an energy crash for a few hours afterwords. After using it for about a month (used approx half of the container) I bought a batch from Costco, and the differece is amazing. Great energy, no crash. Not sure what the issue is, but quality on this product from Amazon is junk!
