I do not understand why you wrote insulin blocks fat storage. this is just not true. I know of plenty of dudes who ran insulin and put on 20 pounds of fat really fast. you really need to know what you are doing with this stuff or it can really be counter productive.. and yes there are plenty of guys who have hurt themselves taking insulin for the average gym rat you just don't need to mess with it at all.
Man I could not agree wore with this entire post. Unless this lifestyle is paying the bills in some way i dont see slin being worth it.
Also as is mentioned by Steve in this post people can very easily gain fat as opposed to muscle using slin unless they really know what they are doing. Unfortunately this is where the problem comes in for those that do not. Often in order to NOT gain fat when using slin the carb intake needs to be pushed lower to the point of entering what I would call an "unsafe zone". Thats bad news IMO....
