Unbranded bottles of Minoxidil/Azelaic on ebay

[mynameisrich]

I've been using a product for a few months now, from 'TheMinoxidilStore' on ebay, however their shipping costs are pretty ridiculous (over 10 USdollars in shipping, when they are shipping to me in the UK, from the UK) so I decided to see if i could get my fix any cheaper.
I find another similar looking seller, with the similar home printed label on bottle looking package, and got me wondering how authentic this stuff really is. Can I trust it?
I definitely want to get my azelaic, because a lot of people say that works wonders, and a lot of these sellers offer 15% minox which is something i'd like to try out.

Any experience, or stories, guys?

Cheers
