I have never tried mesomorph. Razor 8 on the other hand, well I am currently on my second forty serving container. The ingredients list is a little extreme if you are just looking for a little boost, and not a lot of energy. My system tends to adapt to energy supps, and rapidly enough that jack3d didn't last more than a few days before losing impact. With Razor 8, well the term "go big or go home" fits nicely. It is not a light supp, and does not have small impact. If you have a sensitive system and a few cups of coffee makes you jittery, DON'T take Razor 8. Biggest issue is the doseage, unless you are immortal, don't tamper with the doseage! I haven't had to go over what they recomend, and this is my second month (two days minimum off dose per week) They say not to use to replace sleep, and whoo are they right. Also, once you have been Riding the Razor for a few weeks, anything caffinated packs at least double power. (no energy drinks, unless you like feeling like you are in a lightning strike.) Basically if you are gonna use Razor 8, be careful. No stupid "watch me take a huge dose" stuff and you should be fine. Try a half scoop first, if you handle that ok then maybe try a regular dose, two scoops is more than almost anyone should be able to handle safely. (yeah, I saw the moron that DID try that sitting in a corner of my workout area hunched over huffing and puffing) So, try carefully, and if will "blast" you to a new and better level. Remember the saying, "Better, faster, Stronger"
