Every time I go in one of these pound shops there's a different energy drink. Where do they keep coming from? Do they just come up with a different name every week? I think that's probably it, because they all taste the damn same.
So here was have Power Horse. I don't know whether it's meant to give you extra horse power, or grant you the powers of a horse. Although my gallop didn't improve, and I could barely whinny coherently, so I assume it's the former. There's really not much to say. As I've said, it tastes like all the other weirdly named energy drinks you can pick up. It's nothing special, but if you want a cheap pick me up it does the trick.
My rating: 3/5
