I have to try the product first.
This is a beginners error.. And tell people that straight out. Best Response:
YOU: "Actually Dave, you don't.. that's a beginners error a lot of people make in our industry and I'm telling you so you don't make it whatever business you end up joining.

Here's why I say that: If you stop and think about it, I believe you'll agree that you already know our product works and our service is great. If it didn't, we wouldn't have experienced the kind of growth we have. Success like our company has experienced is a CLUE that something is working. Ultimately, it's not about YOU.
It's about others.

Dave, you may get no noticeable result whatsoever with our product, but I guarantee you if you share it with a few people you trust to give you honest opinions and they come back to you with "WOW Dave, this is incredible --it's changed my life, I want more", then Dave you'll be all over this and recommending it to everyone you know having seen the results in people you care about. So with that said, why don't we go ahead and get you started?"

This is a powerful approach, not only to handling this particular objection but to working with prospects in general. That's because it positions you as a coach
Exactly what they need in an upline. It also gives you INSTANT credibility, and really cranks up your "attraction factor" which can substantially increase your sponsoring results.

ALTERNATIVE RESPONSE:
"I have to try it before I can offer it to anyone."
That question is one an untrained amateur always brings up. Certainly they don't need to try it first. "

(If you lose them on this question then they are not coachable and you don't want them anyway.)

YOU: " You already know our product works for if not we would not be experiencing the kind of growth we are having. The Success of our company is proof that the product is working and another proof of that is the very high percentage of reorders we have every month.

It's possible you may get no noticeable results from ENERGY PLUS or Lite. That'snotlikely buit is possible. When you share the product with others many will come back with positive feedback and many will tell you it is changing their life. You will see the results in people you care about.

Assume you a selling battleships, 747's, locomotives, cats cans, surgery equipment, or multitudes of other things that you can not use yourself. Would you insist on learning how to use them all yourself or would you take the companies word for it?"

The initial question should not be if it works for you. It should be if it works for your customers."
