It dose not help the healing process at all. It just puts water in that area and makes it feel like its better.
I worked with a Dr on a few injuries. He works with professional athletes.
He told me to get off the Deca. I was on GH too.
My arm healed twice as fast while off then the other one did while on Deca and GH. Both are myths!
Slat has you covered. All it does is lubricate the joints which alleviates a lot of pain for most advanced athletes/weight lifters in said joints.
To my knowledge raising the dose does not increase lubrication. However I dont know at what point that holds true. For example, im not sure you would get the same lubricating effects from 100mgs of Deca, in comparison to 300mgs of Deca. However you wont see any improvement from 300 to 500, 800 etc.
