Genotropin v Norditropin

I've been on 2iu norditropin for about 6 months. at the end of August i went to Mexico for a week, decided to hire a trainer in PV (best I've ever had) and while there was using the genotropin quick tips little 2iu doses that i didn't have t refrigerate for travel.

I REALLY felt like it was working at the end of that week ad returned slim and tone (slim due more to major montezumas revenge and a flu that killed my appetite)

BUT, I noticed the indentation in fat at the injection site after that trip, also that's when i had the high liver enzymes.

could these little genotropin travel shots be more powerful in some way?

I know there are so many factors here, tie, having been ill etc but i just wonder if anyone else has noticed a major difference between these two brands.
