The product was expired. Nonetheless, I received excellent customer service - was able to exchange it for the MTS beta-alanine.
The MTS beta-alanine is perfect, since each scoop contains 1g (instead of the usual 3.2g, per serving). For those sensitive to the tingling sensation, this is perfect. It's also perfect for those who want to add a little, but not too much, to their plain bcaa's or any other product (like a pre-work out) that doesn't already contain beta-alanine in it.
The scoop size is a good idea. I don't think there's any other beta-alanine supplement out there that offers 1g per scoop (100 servings total)! That means taking 4 scoops, daily, will last 50 days (GNC's beta alanine, for example, is over $24 - 3.2g per scoop for a mere 30 day supply)! Indeed, this product is affordable and the quality is great. It will last too!
Thank you, Marc (and Tiger Fitness), for providing excellent customer service!
