First of all, great stack!!! I'm glad your loving the Blue GENE, especially the boost in libido and the anxiety.
How long since you stopped using it did you experience the pain???
There is a possibility the Cissus could've been helping it. There is a good amount of cissus in BG. THe other possibility is maybe you injured yourself around the same time you stopped BG, making it seem like the Blue Gene was taking care of it?
I'll be interested to see what happens when you start your next cycle...!
