Look in the ozshop source thread there are plenty of reviews. Some people were claiming that they got bunk product (I think this came down to it just being a bunk/heavily underdosed batch) but the positive reviews far outweighs the negative. I’m waiting on a couple of different Nordic products, their Nordic Mast e and their Nordic test e, and I’ll use a test kit to make sure everything is what it claims to be. I’ll keep you posted. In the past, however, I have used their test e 300, started this because my usual street hookup ran out and I had under estimated how much I had needed for my full cycle. The difference between the bioniche brand I started the cycle with and the Nordic was definitely identifiable, it felt like it was dosed perfectly and was a great option to switch to mid cycle when I was in a bit of a pickle.
