This stuff is the real deal----I got my bottle of R-ala from AF store today and it came with a free sample of their new product Thermorexin---I took one pill with an apple about 30 minutes before my workout----I ended up having the most unbelievable back and bi's workout today---felt like I could go forever----If I knew that I wouldn't get addicted to these pills I would buy them in a second---they give you total concentration and intensity without the tremors and increased heart rate----Just want to give props where they are do---
