How to taste a real ranch dressing outisde of the US

When I have been to the South Carolina, US, I fell in love with the popular american Ranch dressing. As an foreigner, I do not know much about this dressing, its origin and sorts, and never bought it in supermarket, but I really liked this one, which was served in McDonalds:

After coming back to Almaty, Kazakhstan, I made several attempts to find this sauce in my home city and feel this taste again. However, they all have failed - there are hundreds of sauces and dressings here: from mustard to caesar dressing, from local manufacturers to Heinz, but there is no ranch - I am not sure if it is simply not popular here or it is just perishable. Even McDonalds Kazakhstan doesn't serve the ranch.

I have only found ranch in a store once, in a plastic, but it was really AWFUL. It was something like horseradish with tons of vinegar and mayonnaise. I was really dissapointed. I am not quite sure if it was deteriorated or it should have tasted like this.

I have several possible ways to obtain ranch dressing now: I can order something through the local import store. They offer this manufacturer (image). I can order Hidden Valley ranch dressing (image) from Amazon. However, I don't want to spend money, wait for a month or two, and get disappointed again.

Now, I have several related questions, that would really help me. I strongly believe that you can know the answers, because you live in this country and some of you buy bottled ranch in supermarkets.

So, does McDonalds ranch somehow differ from the bottled, sold in supermarkets? What kind of ranch dressings do taste the same, fresh and tasty? Is there a chance to order ranch from the US from Amazon and receive it until it deteriorates?

I would like to have the most possible information about this lovely thing.
