No, I think that would work well. In my opinion, slin's effects are mostly anti-catabolic in nature and work as you take it. Slin isn't like gear where you need to take it for an extended period of time, allow it to build up in your system, and then it gets more and more effective. Insulin is designed by nature to do its job immediately so there really isn't any problem with taking it on a staggered schedule or for only your hardest workouts. Each time you use it, it will do what its supposed to do. I don't know if I explained that very well...let me know if its unclear.
