Optimal Harmony stands behind its products and wants to give the consumer a risk free opportunity to try them out.

If the consumer is not completely satisfied the company is willing to refund 100% of the purchase price for:

  • any single quart bottle
  • any single 8 ounce bottle of gel
  • a single quart with a single bottle of gel


This guarantee is good for 90 days from the purchase date.

This guarantee does not apply to gallon bottles or multiple orders of any of the other products. We prefer you try our products first and then purchase larger quantities once you see for yourself how well they work.
