I can see this. When I used Norco (8 weeks) I thought it made me a little more moody and didn't know what the "feel good" part was all about. It was NOT bad though, and it may have been some other stresses in my life causing this. I also reacted very strongly to the Yohimbine in it, which made me think there was more Yohimbine in the Norco than the Alphamine. My Alphamine experience was also atypical. I took half a tub and was not impressed and didn't like it all that much - but the yohimbine sides were non-existent. I decided to finish the second half of the tub off after about a 4 month break and the second half of the tub totally changed my mind. Sometimes I guess you just have very different experiences with products. With Norco, the yohimbine sides felt strong for me for about 2 weeks then totally subsided and even though I didn't get the happy feeling and felt edgy, I was VERY impressed with it. Great appetite suppression and it can really heat you up. It is a product where if you get hot taking 3 pills, it is almost uncomfortable taking 4 pills. I recently found a couple bottles of Adipokinetix from Syntrax that are about 10 years out of code in an old stash of supplements. This has 1R, 2S Norephedrine which I always thought was far superior to regular ephedrine as far as appetite suppression went, and even being 10 years out of code, it was sealed and stored well and it still works great. It has superior appetite suppression to Norco, but not by much and people loved Adipo 10-15 years ago. If Norco can compete without any ephedrine, etc. - it's impressive. As far as actual thermogenesis, I have a feeling Norcodrene probably has the edge over Adipo. As far as the combo appetite suppression/thermogenesis - Norco is probably the best out there.
