I used them for MT2.
They are good, but VERY expensive, easily double the price of what you'll pay elsewhere. I'm not sure if there is much difference in quality, but even if there was, it wouldn't justify the difference in price.
I'm not sure what the price differential for GH peps is, but I imagine it would also be overly inflated.
Try Southern Research co (ships within Australia btw, so no probs with customs etc. Essentially the same as europatan, just much cheaper).
Labpe is the absolute cheapest, but ships from US, so you may run into some trouble, even though you shouldn't as there is nothing illegal in what you are purchasing. I was going to try labpe for my mt2 (getting some more soon), but I won't have time before I fly out to Brisbane as the shipping times are longer. So I just went with Southern Research co. Will probably try Labpe in the future as they are very cheap (I'm talking like 30% of the price of europatan!).
