Xyience Protein [Bad Experience]

[Tikiman]

Over the years I've used around ten different types of protein, including Optimum Nutrition, EAS, GNC, Nature's Best, etc.

I bought a small tub of this to tide me over while I was home on break from college. However, I quickly realized it gave my body terrible intestinal problems and constipation, backing up my system and causing me to lose weight. I couldn't run at all lately due to stomach pains, and it took me around 2 weeks to discover the cause!

Needless to say, I'm back to ON Gold Standard for a while. Anyone have a similar experience, or an idea as to what would've caused this. I tried searching the ingredients for something out of place, but no luck there.

I didn't know they made protein powder..ya sure ya didn't pick up some of their NO powder?

What flavor was it?

Definitely protein powder, checked the label, etc. Was purchased at GNC and isn't expired. The flavor is Vanilla, not that bad of a taste either as I recall.
