Keep in mind everyone responds differently to Clen. henrock360, how do you handle typical stims? I personally do really well with clen and experience very little of the bad sides while dropping fat well and I do feel it has an anti-catabolic effect, at least for me.
But others HATE it as they experience terrible headaches, shakiness, bad cramping, and a lot of trouble sleeping. Some of this can be attributed to too large a dose, but others simply react poorly. Often times these individuals will have much greater success with the ECA stack which also acts on the Beta-2 receptors.
