Being a manufacturer goes far beyond formulation, packaging and shipping.  Our experience has taught us how to insure packaging compatibility to avoid contamination or alteration of packaging contents, and how to stabilize our products for maximum shelf life without compromising test results.

If any of the products represented by DTI do not perform as stated in the packaging insert when all instructions have been carefully followed, they may be returned for credit or refund.  Items must be returned within 14 business days of receipt.
