TOPIC: Has anyone use muscle gun for healing and molding?

I’m curious to know if anyone uses muscle gun to help with recovery or used it to help molding with filler to push in shape?

I saw on Reddit it can help with Jelqing and increase circulation when having stretching fatigue

Link and picture would be appreciated

From the looks of it i would advise against it, seems totally unprecise
