I know it just seems like I'm plugging my own product, but I honestly feel that if you like those products you'll like MyoGenX more.
The admin here (BRR) was very satisfied with it, and there was a mod on steroid.com who used MyoGenX as his ONLY PCT (!) and was so impressed that he made his thread/log about it a Sticky in the Supplement forum...
Again, I'm not trying to come off as just trying to make a buck, but I honestly feel confidant that if you try my product you'll like it much more than the others you mentioned.
Maybe I'm just very proud of being the first person to ever bring this herb to the nutritional market, but I think you'd be very happy with it....at the very least, go check out steroid.com for some user feedback on it and make your decision based on ALL available feedback.
