Hmmm...Wellness isn't one of the ones I've heard complaints about. Why did you swap him? Specifically, what aspect were you trying to change (more of x? less of x?) by switching to Evo...maybe there is another brand out there that you could get the same from that someone could suggest...
Yes, I would suspect the same issues would happen again.
Like I said, maybe there is just something in Evo that doesn't agree with him.
Also, I would think the ProPec would be taking effect by now...what dosage is he getting? Should be 1cc...?
