By reducing TGF Beta 1 and increasing Oxytocin, old blood becomes young and muscle, liver, and neuron regeneration are restored.

What is interesting is there are publications that show reduced NAD+ increases TGF Beta 1.
CD38 is used to generate Oxytocin. So higher NAD+ will increase Oxytocin.
Some companies use CD38 inhibitors to increase NAD+. This will reduce Oxytocin.
