Allergic to protein supplement?

[Ranxerox]

So Ive started using USN mass grow (not sure of name), but i think im allergic to some of the ingredients, as it makes me feel bloated and nauseous, and i have to prevent myself from vomiting during training. Any ideas? I hope i can still use it as i have 2 kilos of the stuff and i dont want to have to throw it away.

Have you checked the expiry date? Are you mixing it with just water?

Go off it for now. If you feel better try adding it to your diet again, if the same symptoms occur chuck the stuff out or give it to somebody.

Are you allergic to soy? Is there soy in the product?
