I agree. I’m absolutely convinced that the vehicle is a critical component. 4AD products for body building are aimed at high availability systemically, so none of them will be optimal for our purposes.
I’ve said this many times, but it seems to fall on deaf ears: What about MSM? It does pretty much what DMSO does but without the garlic taste or skin irritability issues. It’s used widely for delivery of arthritic medicines, as it has been shown to be available at the joint capsules (now that’s deep penetration!). It would seem a logical choice. Another thing about it is it increases permiability of the cell wall. Couple that with a low molecular weight and a bulldozer like ability to carry other actives with it, dissolves to 16% in water by volume, and is a useful skeletal supplement in its own right. It’s a food rather than a drug. Damn it’s good for you health!
Oh, it’s cheap too….
