My vendor is out of the wolverine stack but has BPC/TB4 in stock. He says this is better than BPC/TB500. I’ve got family members using the Wolverine for knee/elbow/shoulder injuries. We also give it to our dog for his hips. Just not sure I want to switch from what we know has been helping. Any insight into this? I know that the TB500 is a fragment of the Tb4 but not sure I want all the “extras” as opposed to what the TB500 specifically targets.
