If you're looking for a stack that isn't too harsh, something like Formasurge/Endosurge/Vanillean would be great.
I'm not really a fan of Cortisol inhibitors, especially for more mature lifters, since they tend to aggravate joints and because cortisol stimulates post-workout anti-inflammatory mechanisms and protein turnover, so I'd leave Lean Xtreme out.
Erase could be substituted for Formasurge, but you definitely wouldn't need both, and DAA with Endosurge and any AI is very popular and a lot of fun!
As for the Dermacrine, absolutely you could wait for it - adding it to a stack like Forma/Endo/Vanillean would be unreal. However, if you want to get things underway ASAP, you can still make solid progress without it on the rest of the stack.
