Menastil for Joint Pain?

Which product should I use for joint pain?

Good question
That probably depends on which specific joint, or the level of pain associated with it.
As a general rule, these are the recommendations:

The "smaller" joints will probably respond well to Menastil
The "larger" and "deeper" joints will probably respond better to a "stronger" product, which will soon be available.

Smaller joints would be the finger, wrist, elbow, knee, ankle, etc.
Larger joints would include the shoulder and hip.

However, you may find that for you personally one or the other will work better.
Joint pain can be quite intense and will usually need several applications.
Our friend Jeff W. had someone try Menastil on his knee. When after one application his knee still hurt, the claim was made that "It doesn't work."
When in fact this person needed several applications and he would feel results within days. This was done, with a positive outcome.
Also using a stronger version would have been helpful in this incidence, and that will be an option in the near future.
