Contacted Amazon as the bottle that arrived does not look anything like the advertised item. The label states GF1 instead of IGF-1 and looks like a cheaper label. I've gave 1 star based on the fact I have doubts on the authenticity and this makes me uneasy.
The product itself I'd give 5 stars based on the previous 10 bottles I've used, it has just the right consistency and isn't sickly sweet tasting like most proteins.
Edit: Had confirmation from seller within the hour so top marks to them. USN is currently rebranding so this is the latest product. I have since returned to the USN website and they are slowly updating the pictures.Seems odd to drop the IGF-1 label but maybe the world is running out of the 'i' vowel.
